Hot Shoe Menu - /MENU L B
B:HOTSHOE OFF Toggle the hot shoe on or off as needed. Press /MENU L B. Display will show Hotshoe Input Disabled. Toggling the hot shoe input to OFF may be useful when mounting the MultiMAX on a cold shoe, or when you desire the trigger input to come from PORT 1 and not the hot shoe it is mounted in. Press /MENU L B again and the display will read Hot shoe Input Enabled.
Custom ID Menu - /MENU L C
C:CUSTOM ID This menu only appears if you have a Custom ID and you have a US/FCC radio. What is a Custom ID? It is a private channel on a MultiMAX. In hyper-crowded shooting environments, Custom IDs give you the confidence to know that your remote flash or camera can only be triggered by you and not any other photographer. It is an exclusive code installed on top of an existing PocketWizard frequency, usually replacing Channel 17 with your new custom code and frequency combination. No other manufacturer offers such a unique and valuable service. Because Custom IDs require a firmware modification, this service is only available directly through LPA Design. Contact us via our inquiries page on: PocketWizard.com: http://www.pocketwizard.com/contact/inquiry/
Move Custom ID Frequency A:CUSTOM ID FREQ

/MENU L C A

Use this menu to move your Custom IDs to a different frequency. This is useful if there is RF noise on your Custom IDs default frequency (see Noise Sniffer for more information) or if another user has a Custom ID on your default frequency. Select the Custom ID you want to move to a different frequency by pressing A or B. Only Quad-Triggering Channel IDs (Channels 17 - 32) can be moved. Only your first 2 Custom IDs can be moved. On the next screen you will see: SAME AS CHAN XX and a number. The number is the frequency - 349.000 = 349.000 MHz. Using the arrow keys, move your Custom ID to the frequency you want and press /MENU. Every frequency is shared by a MultiMAX Quad-Triggering Channel. iv
When the display says SAME AS CHAN 21 and the frequency displayed is 348500 that means that your Custom ID will use the same frequency that is in use on standard Channel 21 - Photographers using that channel cant trigger you and you cant trigger them, but if you try to trigger at the exact same time then you may interfere with each other and cause a loss of triggers.

View Custom ID B:VIEW CUSTOM ID

/MENU L C B

Displays a list of your installed Custom IDs and what frequency they are using.
Multi-Zone Receive (Receive Only)
The MultiMAX now allows you to select more than one Zone for receive. You can receive on any combination of Zones. If you select A and B, for example, any trigger on either A or B will trigger the radio. This feature allows another avenue of creative control for zones. EXAMPLE: Two photographers are working the same venue. Each has their own portable flash system that they move with them, and they share area flashes that light the ceiling. One photographer could use Zone A for his nearby flashes while the other photographer uses Zone B. The receiver triggering the area flashes could be set to A & B.

Menu Indicator

If a menu in the MultiMAX contains more than four items, there is a now an indicator that shows there are more choices above or below the current list. Just use the arrow keys to see the other menu items.
Signal Strength Indicator (Receive Only)
The Signal Indicator (antenna level bars like on a cell phone) now performs two functions: 1. Noise Meter: If your radio has NOT been triggered, the Signal Indicator will show steady noise in the area. More bars = Good radio environment (less noise). If your Signal Indicator shows fewer bars then there is a strong source of constant interference in the area. The Signal Indicator will not show transient or brief interference like from another PocketWizard user. Noise Sniffer SLOW scan might help there. 2. If your radio has been triggered, the Signal Indicator shows the strength of the last trigger received. More bars = clear signal.
Noise Sniffer - /MENU B L (Receive Only)
L:NOISE SNIFFER The Noise Sniffer is a MultiMAX tool for troubleshooting RF issues. It can show the relative radio noise for the MultiMAX channel and frequency displayed. To access the Noise Sniffer set the MultiMAX to RECEIVE then press /MENU B L. In Noise Sniffer mode, use the arrow keys to cycle through the channels. If you have a Custom ID, it will use the correct frequency for your Custom ID channel. Place the MultiMAX in a location you intend to use, or walk around with the MultiMAX to help pinpoint noise sources. Move the antenna closer to cable-runs and metal structures to see if they are sources of RF noise on your channel. 127 = maximum noise the MultiMAX can sense. Lower is better. Readings below 40 are unlikely. What should the numbers be? As low as possible and still have reliable operation. These numbers are only for comparing one channel to another or for verifying RF noise as a possible factor on your channel or location of choice. There is no perfect number, so operation needs to be evaluated in context with these numbers. vi

FAST Noise displays noise readings as fast as the MultiMAX can sample. If this number is consistently high, there is a strong interference source in the area. It samples so quickly, however, that brief transient noise is hard to note. SLOW Noise displays the highest noise sample out of the last 150. This will help you see live transient or very brief noise like another PocketWizard radio triggering. PEAK Noise displays the highest noise reading (FAST or SLOW) since you last cleared it or changed channels. This will help you see the highest noise moment, but it is not real time. It is good for catching the most transient of interference or as a reference when evaluating a better location. Reset using the A key. When all three numbers are roughly equal, this represents the base line RF noise for that channel in that location. Lower is better. Choose a channel with less noise or move to a less noisy area. If FAST is low compared to SLOW or PEAK then there may be transient RF noise in the area. Something is probably creating RF noise on the channel but it is only happening sporadically. If possible, use another channel or move away from the interference source. If SLOW only shows occasional spikes, you may be fine. If the units LED blinks in any manner other than the normal powered on blink (once every two seconds), then the source of the noise is another PocketWizard on your frequency! A MultiMAX mounted near the ground (within a few feet) may display a low noise reading and still have poor performance. This is because the ground absorbs radio energy. It absorbs the signal from your PocketWizards, so performance worsens in general. It also absorbs the ambient RF noise so the MultiMAX Noise Sniffer shows less noise present. In this situation a small amount of RF noise might have a much more extreme effect on reception reliability as one problem exacerbates the other.
Radio Relay (Repeater) Mode (Receive Only)
This mode lets you deploy another MultiMAX to increase your range. It receives and transmits on the same channel. To activate Radio Relay (Repeater), set the MultiMAX to RECEIVE on your channel of choice, then press the L key twice. You should now see RPT on the display. Pressing L toggles between these modes: RLY = Standard Camera Relay. It also displays the channel to be used when Transmitting. This is set in TRANSMIT mode. Read more about Relay Mode in your MultiMAX manual. RPT = Radio Relay (Repeater). There is no transmit channel to set in this mode. It uses the channel as displayed in the upper right. No relay function (off = no display). The radio operates only as a receiver. Make sure the zone of the repeater is set to one you are using on your transmitter. You can use all of the other zones on your transmitting unit and the RPT MultiMAX will relay your selected zones as long as it is also on one of the selected zones. Deploy the repeating MultiMAX where it effectively triggers the remote unit, and can be effectively triggered by your transmitting unit.

IMPORTANT: Do not deploy more than one repeater to cover the same remote.
Extra repeating units will step on each other and make it difficult for your remote to get a trigger bathing an area with repeaters is likely to worsen the remotes performance. You can use additional units to further increase the distance from your remote, but each repeater should be deployed to cover only one leg of the journey. Each repeating unit increases the radio delay by ~0.0018 seconds (~1/800). If you are using the RPT unit for remote camera triggering, this small delay will be unnoticeable. If you are using the RPT unit for remote flash triggering, this may affect the fastest shutter speed you can use. viii
Suggestions for remote camera triggering:
Eliminate as many RF interference issues as possible. Maintain a line of sight between the units. Keep the antennas parallel and at least 12 apart. Make sure the radios, and especially the antennas, are not near any large metal, concrete, or high water-content objects. People and trees are mostly water! Make sure they are not blocked by these objects or by hills. Crowds gathering between you and your remotes will reduce range. Try to keep the antennas above the heads of crowds. PocketWizard radios will have reduced performance if deployed close to the ground. Try to get them up high 4 feet or higher improves range dramatically. Consider using any miniphone/headphone extension cable (including a PocketWizard MMX cable) to locate the receiver higher up. Avoid mounting them to long metal railings or other building structures. Avoid mounting them near long cable runs for other equipment or close to building wiring. Do not wrap connecting cables around the antenna. Keep them away from the antenna. Use right angle connectors whenever possible. Do not affix the radio by taping the antenna to something. Especially, do not use duct tape or any tape containing metal fibers on the antenna. Avoid using long cable runs with PocketWizard radios. If you must use a long cable run, deploy ferrite chokes (http://www.radioshack.com/product/index. jsp?productId=2103222) near the PocketWizard end of the long run. Use more than one ferrite choke when possible. Place them 6 to 12 inches from the radio and from each other. Dead spots have a number of causes, but the solution is usually the same: move the unit a few inches or feet away from the problem area. ix
For remote finish line cameras or any remote camera where a long motor drive burst is desired, consider the following: Set a long contact time (for example, 1.50 seconds) on the remote receiving unit. If range is an issue or remote operation is intermittent, this will help. If any single trigger is received, a long burst is guaranteed. Contact time is set by pressing * B A. Trying to get a remote camera to trigger as fast as the master camera in your hands by having the transmitting PocketWizard connected to the shoe or PC of the master may be problematic. Cameras are not designed to be triggered like a high speed hot shoe flash for example five very short triggers in under one second. This may confuse the remote camera, cause it to not trigger, or cause it to trigger sporadically. Instead of relying on the shoe trigger, use either: A button cable (BT1 or BT3) connected to PORT 1 of the transmitting unit. Tape this button to the grip of the master camera. A P cable (pre-release/pre-trigger cable) connected from the motor drive of the camera in your hands to PORT 1 of the transmitting MultiMAX. This causes the transmitting unit to be triggered as you press all the way down on your cameras shutter release. You must use a P cable and it must be set to OFF for this to function properly.

PocketWizard Utility

Your MultiMAX has a USB port which allows it to be easily updated to the latest firmware using the PocketWizard Utility. The PocketWizard Utility can be downloaded on our website at http://www.PocketWizard.com/support/downloads/ To connect your USB-enabled MultiMAX to your computer, please follow these steps: 1. 2. 3. 4. 5. 6. Turn off the MultiMAX radio and make sure you have fresh batteries installed. Press and hold the backlight key (located between MENU and TEST) as you turn the MultiMAX on to TRANSMIT. Note that the STATUS LED blinks steadily and the LCD remains blank. This confirms the radio is in USB mode. Make sure the PocketWizard Utility is running on your computer and no other PocketWizard radios are connected to it. Connect your MultiMAX radio to your computer using a standard Mini-B USB cable and note that your MultiMAX radio appears in the PocketWizard Utility. To update your radio, click Check For Updates in the Maintenance Tab. Most updates require a full factory reset (see the RESET section on Page 29 in your MultiMAX Owners Manual). Be sure to write down any special settings like Contact Time, etc., before you update your radio.
Consider updating all the USB-enabled MultiMAX radios in your system to the same firmware. Older MultiMAX radios that do not have a USB port will continue to work as part of your MultiMAX system. The older non-USB radios cannot get the new features, but will still perform their original functions normally when paired with USB-enabled radios.

Classic Channels

Classic channels are compatible with early PocketWizard models and the PocketWizard Plus. Selective QuadTriggering is only available in channels 17 through 32. In channels 1 through 16 the display will show CLASSIC CHANNEL and zones A B C D do not appear. The A key simply toggles the remote receivers on or off and is displayed on the main screen as R. It is not possible to toggle both the remote (A key) and the local flash (L key) off at the same time when using a CLASSIC CHANNEL. Operation on these channels is identical to the function of the LOCAL / BOTH / REMOTE switch found on PocketWizard Plus and Classic Transmitters.

L key toggles Relay when TheRelay Mode section, Mode39, for using a MultiMAX (set for RECEIVE mode). See the Page more information.

True Confirmation

Because the MultiMAX is a true transceiver it automatically confirms triggering. It can perform this on two levels: it confirms the round trip radio signal and can confirm actual flash sync with an optional flash confirmation cable. It does this for all Quad-Triggering zones on every trigger. Confirmation is indicated visually on the main screen and audibly using beep modes.
For audible confirmation settings see the Beep Menu section, Page 28.
Radio confirmation is displayed on TRANSMIT units in the A B C D area of the LCD. An inverted letter shows an error. A normal letter shows confirmation. During normal operation the display will show selected and active A B C D zones not inverted. Confirmation will occur on every trigger and only in the event of an error will the zone letters invert.
Optional Flash Confirmation Cable
Using the flash confirmation cable the MultiMAX can confirm flash sync for all four zones on every trigger. 1. Attach flash confirmation cable to PORT 1 for each MultiMAX (set for RECEIVE mode) 2. Locate the sensor so that it can only see the flash from the correct flash unit 3. Press the TEST button on a MultiMAX (set for TRANSMIT mode) to test flash confirmation. Correct flash confirmation is displayed on the main screen with a flash icon to the right of each zone performing flash confirmation. In the event of an error (either no flash was detected or the radio link was incomplete) the zone letter and the flash icon will invert A MultiMAX (set for TRANSMIT mode) will look for RECEIVE units and confirm the radio link after each of these operations: Every trigger Power on or switch from RECEIVE to TRANSMIT Channel change Zone change (including L) Exiting the menu system

Set Contact Time Screen

time is NOT the length of time a MultiMAX (set for will N Contactradio triggering signal. Contact time affects PORT 1 TRANSMIT2mode)and does send a and PORT only not affect radio trigger transmission. Pressing and holding TEST on a MultiMAX (set for TRANSMIT mode) will continuously send the radio trigger signal and hold the contact on a MultiMAX (set for RECEIVE) as well as the TRANSMIT unit. When the TEST button is released each units contact time will then begin.
0.08 seconds can theoretically accommodate shooting with remote flash up to 12 FPS (Frames Per Second), however testing with your specific equipment may be required. Setting the Contact Time to 0.01 seconds will work with most cameras and flashes, and offers the fastest FPS (up to 30) with some PocketWizard products. For more information about maximum frame rates and optimum settings, please visit the User Forum of our website at: www.pocketwizard.com
For triggering remote cameras, a longer contact time allows for continuous repeatable motor drive triggering (example: 5 frame bursts every trigger). It also allows for controlled bulb exposure. Example of Burst Shooting: If a remote camera is capable of firing 3 frames per second in continuous motor drive, then a contact time of 1 second will always result in this remote camera triggering for 3 exposures Example of Bulb / Shutter Held Open: Set the contact time for the desired bulb exposure time and set the camera to bulb or B mode. When triggered the shutter will remain open for the contact time For triggering a remote flash contact time can act as a flash recycle lockout. Example of Flash Recycle Lockout: To guarantee that a flash cannot be triggered faster then its recycle time, set the contact time to be just longer than the recycle time method of flash recycle lockout does not all flash systems as some Thisrecycle while the sync contact is held.

/MENU A C
Enters the Multipop interval setting screen. This mode is for triggering a flash multiple times from one trigger. It can be used during one long exposure to increase depth of field or for special effect sequencing. The interval setting is normally used to set a safe flash recycling time, while the count is set to the number of flashes or pops desired. Multipop is identical in function to Intervalometer with one exception: the multipop interval range has finer resolution; from 0.01 to 999.99 seconds in 0.01 (1/100) second increments. This allows for finer control when setting flash recycle time. This mode can be used for cameras or flash units.

This means that a remote camera or flash will remain triggered with only a 1/100 second release between contacts. This short released time may not be long enough to re-trigger some cameras or flash units. If this is the case, set the contact time lower. /MENU A D

Multiple mechanical systems cameras that have many changeable mechanically interacting parts (film backs, motor drives, lens shutters) are likely to have different lag times with different hardware combinations. A leaf shutter is in the lens so changing lenses on a leaf shutter camera will change lag time. In some medium format cameras having the film back loaded versus unloaded can make a significant difference. For consistent results always use the same components (lens, body, and film back combination for example) each time Auto-focus and exposure computers some auto-focus and exposure systems will introduce widely varying lag times as lens travel and exposure calculations can take unpredictable amounts of time. An electronic camera set to full manual generally provides the most consistent lag times
Lag Time Measurement /MENU A A C L (RECEIVE units only)
The first step to camera synchronization or equalization is measuring a cameras lag time (triggering delay). The MultiMAX can measure a cameras lag time in most delay modes. Knowing your cameras lag time is critical for camera equalization, but can also be useful in special effects, industrial, commercial, or other photography that requires critical trigger timing. Using the information above set up your camera for best equalization performance. Attach a MultiMAX (set for RECEIVE mode) to the camera as follows: 1. Place a MultiMAX in the cameras hot shoe or attach a cable from the cameras PC terminal to PORT 1 2. Attach the cable from PORT 2 to the cameras motor drive. If available, use a Pre-Release cable 3. Press /MENU A A C for a standard delay mode where lag times can be measured 4. The screen should display Set Delay Using A B C D L and show a numeric value. Press TEST. The unit will trigger the camera and time the delay until a sync pulse is sensed from the hot shoe or lens 5. Press TEST every few seconds to find the fastest and slowest lag times for the camera. Usually the first press of TEST will yield a very different number from later measurements. Ignore the first reading. 5 to 15 lag time measurements after the first one should yield consistent results and give a gauge of the fastest and slowest times 6. Using steps 1 through 5, measure and record the fastest and slowest lag times for each camera you wish to equalize. Subtract the fastest from the slowest and record this number as the cameras lag time variation
Speed is not the most important factor in camera equalization, consistency is. If

One Unit Equalization

To equalize two cameras and one flash at 1/125 with one MultiMAX, follow these steps: 1. Set the MultiMAX to RECEIVE mode 2. Measure lag times of cameras as described and record the fastest lag for each 3. Determine which camera is faster and which is slower overall 4. Determine the delay time a. If the slow camera is more consistent use this formula: i. lower Cameras Fastest Lag Time MINUS Faster Cameras Fastest Lag Time S MINUS 0.0025 {calculated safety margin} b. If the fast camera is more consistent use this formula: i. lower Cameras Fastest Lag Time MINUS Faster Cameras Fastest Lag Time S PLUS 0.0025 {calculated safety margin} 5. Press /MENU A A B then enter the calculated delay time from Step 4 6. Attach the slower cameras motor drive to PORT 1 7. Attach the faster cameras motor drive to PORT 2 8. Attach the flash to the more consistent (smallest lag time variance) camera 9. Trigger the RECEIVE unit either from the TEST key or from a TRANSMIT unit

Two Unit Equalization

Two Unit Equalization is basically the same as above, but allows the two cameras to be more remote. The difference in calculations compensates for radio trigger delay. 1. Set one MultiMAX to RECEIVE mode, and one to TRANSMIT mode 2. Using the RECEIVE unit, measure the lag times of each camera as described above and record the fastest lag for each 3. Determine which camera is faster and which is slower overall 4. Determine the delay time a.

Channels

The MultiMAX is a 32 channel digital radio slave. Each MultiMAX channel represents a digital code transmitted on specific PocketWizard radio frequencies. This enables many photographers to work in the same area. It also enables a photographer to control multiple remote devices (cameras, flash units, etc). A MultiMAX (set for TRANSMIT mode) will trigger any number of MultiMAX units (set for RECEIVE mode) set to the same channel. Units set to different channels will not interfere with each other. From the main screen press the keys to change channels. Some MultiMAX features are only available on higher channels. Refer to the table below for features / channels availability:
Features Digital Radio Signal. Delay including Rear Curtain Sync Intervalometer Multipop Relay Mode Selective Quad-Triggering Confirmation (Radio and Flash) Fast Mode SpeedCycler Channels 1-16 X X X X X Channels 17-32 X X X X X X X X X

Contact time is the length of time that CAMERA / PORT 1 or FLASH /PORT 2 outputs remain contacted. The default Contact Time of 0.08 is enough to trigger most camera motor drives and flashes. Many photographers will never need to adjust this number. time is how held N Contact For example,long the internal switch isto 3 closed. if the contact time is set
seconds and a camera motor drive is attached to a MultiMAX, when the MultiMAX triggers the camera it will hold the contact for 3 seconds. This is identical to pressing and holding the cameras trigger button for 3 seconds. The contact time starts as soon as any input is complete. Input can be from any of the following sources: TEST button is pressed, hot shoe is triggered, or radio trigger is received. Additional triggers occurring during contact time are ignored.

Only the zone just triggered will display proper confirmation

The amount of drift or lag time inconsistency determines the highest shutter speed at which a camera will reliably equalize. The following table should be used as a starting point for testing purposes only. The numbers in this table are based on a 1/1000th or faster flash duration.

blade travel A wider N Leaf shutters have different shutterthe amount oftimes depending onAaperture.aperture aperture takes longer and reduces variance allowed. smaller takes less time thereby increasing the allowable variance. (A leaf shutter set to F:4.0, for example, may reduce the variance to the same as a focal plane camera).
f your than the N Iuse thecameras maximum sync speed is slower does not number listed then you must slower sync speed. Camera equalization give a camera faster sync speeds than the camera is designed to handle. For all shutters it can be assumed that a camera with faster external flash sync speeds (X sync) will have faster shutter travel than cameras with slower X sync speeds. Faster shutter travel times increase the allowable variance. The table above is based on the following shutter travel times: Focal Plane (35mm) 1/1000 (0.0010) to open, 1/1000 to close Leaf shutter at f: 8.0 1/2000 (0.0005) to open, 1/2000 to close If a flash is generating light while the shutter is moving then you will see the shutter in the exposure for focal plane shutters. You will see a loss in F stop exposure using a leaf shutter if the flash is generating light as the shutter aperture opens or closes. A variable flash duration will also affect these calculations. A slow flash is visible for longer and more likely to affect exposure while the shutter is in motion. A short flash duration reduces the likelihood of timing variances affecting the exposure. It is difficult to measure a shutters travel time or a flash units duration and it usually requires extremely expensive test equipment. Some electronic flash manufacturers print their flash durations in their manual. The best method for understanding your equipments equalization capabilities is to shoot many test exposures over a range of settings.

One Unit Equalization

To equalize two cameras and one flash at 1/125 with one MultiMAX, follow these steps: 1. Set the MultiMAX to RECEIVE mode 2. Measure lag times of cameras as described and record the fastest lag for each 3. Determine which camera is faster and which is slower overall 4. Determine the delay time a. If the slow camera is more consistent use this formula: i. lower Cameras Fastest Lag Time MINUS Faster Cameras Fastest Lag Time S MINUS 0.0025 {calculated safety margin} b. If the fast camera is more consistent use this formula: i. lower Cameras Fastest Lag Time MINUS Faster Cameras Fastest Lag Time S PLUS 0.0025 {calculated safety margin} 5. Press /MENU A A B then enter the calculated delay time from Step 4 6. Attach the slower cameras motor drive to PORT 1 7. Attach the faster cameras motor drive to PORT 2 8. Attach the flash to the more consistent (smallest lag time variance) camera 9. Trigger the RECEIVE unit either from the TEST key or from a TRANSMIT unit

Two Unit Equalization

Two Unit Equalization is basically the same as above, but allows the two cameras to be more remote. The difference in calculations compensates for radio trigger delay. 1. Set one MultiMAX to RECEIVE mode, and one to TRANSMIT mode 2. Using the RECEIVE unit, measure the lag times of each camera as described above and record the fastest lag for each 3. Determine which camera is faster and which is slower overall 4. Determine the delay time a. If the slow camera is more consistent use this formula: Slower Cameras Fastest Lag Time MINUS Faster Cameras Fastest Lag Time MINUS 0.0030 {calculated safety margin} b. If the fast camera is more consistent use this formula: Slower Cameras Fastest Lag Time MINUS Faster Cameras Fastest Lag Time PLUS 0.0020 {calculated safety margin} 5. On the RECEIVE unit press /MENU A A A. Enter the time from Step 4 6. Attach the slower cameras motor drive to PORT 2 on the TRANSMIT unit. Do not leave the MultiMAX (set for TRANSMIT mode) in the hot shoe or have the PC terminal attached to PORT 1 as this may cause a looping or lock-up situation 7. Attach the faster cameras motor drive to either PORT on the RECEIVE unit 8. Attach the flash to the more consistent (smallest lag time variance) camera 9. Trigger the system from the TRANSMIT units TEST key
If using both MultiMAX units as RECEIVE units being triggered by any PocketWizard Transmitter follow these steps: 1. Set both units to RECEIVE mode 2.

Equalization Adjustments

With all the variable factors above it may seem that performing the math necessary for equalization is daunting. Here are some techniques for fine- tuning or adjusting equalization times without using specific math: On some 35mm cameras you can gauge timing without using film. If your camera allows triggering with the film back open you can verify synchronization visually. 1. Perform the steps above to get basic equalization started 2. Point the flash at a blank wall 3. On the camera NOT attached to the flash, set the shutter speed to 1/60 4. Open that cameras back 5. Point the camera at the same wall as the flash 6. As the camera and flash are being triggered look through the shutter plane through the lens at the light from the flash hitting the wall. CAUTION: MAKE SURE the flash is set to a comfortable level for your eyes! 7. Note the shape of the light burst. If it is a perfect bright circle then the camera is in sync. If the circle is dark or has a hard line running along one edge then the camera is not in sync. The hard line is the shutter in motion while the flash is still generating light 8. Adjust the shutter speed up or down until you see a perfect circle
The delay time setting screen is instantly active. While in numeric entry mode you
can adjust the delay up or down and the displayed value will be executed on the next trigger. Using the through-the-back method above or by shooting film, Polaroid, or digital you can adjust the delay and view the results to more suit your specific cameras timings.
The mathematical formulas used thus far are designed for equalizing at 1/125. The final offset number (0.0025 for example) may need to be adjusted when attempting to equalize at faster shutter speeds or slower ones with wide lag variation cameras. The offset number tries to move the flash burst to the middle of the exposure to compensate for drifting lag time. Experiment with different offsets to fine tune your shutter speed, flash duration, and camera timing combinations. Too long or short of an offset and you limit a cameras ability to get the exposure if the lag drifts, even by a small amount.

techniques. As more information becomes available it will be posted there.

Sustaining High Performance
Long distance performance from your MultiMAX depends on the orientation and position of the units. Whenever possible, try to maintain a line of sight between the units and keep the antennas parallel. Make sure they are not near any large metal, concrete, or high water-content objects. People and trees are mostly water! Make sure they are not blocked by these objects or by hills.

Positioning

Acceptable

Blocking Signal

Maintain at least 12" distance between antennas. Avoid direct antenna contact with anything metallic. Dead spots have a number of causes, but the solution is usually the same: move the unit a few inches or feet away from the problem area.

Mounting suggestion.

Mount the remote PocketWizard so that the antenna is completely above the top edge of the flash pack and away from any metal (light modifiers, stands, etc.).
