Inserting the Batteries

Slide the battery chamber cover as shown in the figure to open.
Insert four AA batteries, making sure the plus/ minus markings (+, -) match the diagram inside the battery chamber cover.

Types of Batteries

This flash unit uses four AA batteries of the same type, as shown below. - Alkaline battery (LR6) - Lithium battery (FR6) - Nickel-Metal Hydride battery (Ni-MH) (Nickel manganese (Ni-Mn) and nickel cadmium (NiCd) batteries cannot be used.) For information about recycling times and total number of flashes, refer to Specifications on page 88. If the indicators on the LCD panel or the ready lamp does not light up, the batteries may be exhausted or not inserted correctly. Verify the orientation of the batteries or, if the indicators and ready lamp still do not light up, replace them with new batteries. If you let the flash unit discharge successively using lithium batteries, the batteries will overheat, activating a safety circuit that temporarily disables the flash unit. If this occurs, rest the flash unit so that the temperature of the batteries returns to normal.
Using the Optional External Power Source
Use the optional TR Power Pack-3 (sold separately) as an external power source. For information on how to use the TR Power Pack-3 and connect to the flash unit, refer to the manual provided with the TR Power Pack-3. For information on how to recharge the flash unit using the TR Power Pack-3, refer to Charging the AF540FGZ with the Optional External Power Source on page 16. The TR Power Pack-2 cannot be used with the AF540FGZ for mechanical reasons. The external power source uses six C-size alkaline batteries (LR14). (Nickel cadmium (Ni-Cd) batteries cannot be used in the TR Power Pack-3.)

Cameras that Support Each Flash Mode (page 60) 2. Whether you can use the desired function with the combination of your camera and the flash mode you have set. Functions Related to Each Flash Mode (page 64 - 71)

TTL auto flash (TTL)

Based on the amount of light reflected off the film of the camera, the camera adjusts the flash output automatically to obtain a correct exposure. Refer to page 27 for instructions on how to use this flash mode.

Auto flash (A)

The built-in flash metering sensor adjusts the flash output automatically. Use with cameras that are not PTTL or TTL Auto flash compatible. Refer to page 28 for instructions on how to use this flash mode.

Confirm that the subject is within the effective flash range and the ready lamp is lit. Then take a picture. In the following cameras, if the correct flash output is obtained, the flash mode indicator and ( ) in the viewfinder will blink. 645, LX, MZ-M/ZX-M For details, refer to Auto Check Display on page 11.

Using the Sync Mode

The AF540FGZ has the following sync modes. Select the mode best suited for the subject. Before photographing, confirm the following. 1. Whether your camera supports the desired sync mode. Cameras that Support Each Sync Mode (page 62) 2. Whether you can use the desired sync mode with the combination of your camera and the flash mode you have set. Functions Related to Each Flash Mode (page 64 - 71) 3. Restrictions for the use of each sync mode. Sync Mode Restrictions (page 72 - 76)
Trailing Curtain Sync Mode
In this sync mode, the flash is discharged at the instant the second curtain begins its travel. This mode will freeze the subject with a blur appearing after the subject under a slow shutter speed condition. Refer to page 33 for instructions on how to use this sync mode.

High-Speed Sync Mode

This sync mode will enable flash synchronization with shutter speeds faster than the X-sync speed. Since there is no sync speed limitation, high-speed sync is effective for fill-flash in daylight. Refer to page 34 for instructions on how to use this sync mode.
Contrast Control Sync Mode
This sync mode enables you to photograph with multiple flash units, utilizing the difference of the light intensity of each flash unit. The ratio of flash light intensity between the flash unit set to this sync mode and the other flash unit is 1:2. Refer to page 36 for instructions on how to use this sync mode.
Leading Curtain Sync Mode
This is the most commonly used sync mode. In this mode, the flash discharges at the instant the first shutter curtain completes its travel. You can use this mode with the shutter speed set to the X-sync speed or slower. Refer to page 33 for instructions on how to use this sync mode.
Refer to page 32 for the features and conditions of use of this sync mode.
Set the power switch to the (ON) position. Set the sync mode switch to leading curtain sync ( ). Confirm that the subject is within the effective flash range and the ready lamp is lit. Then take a picture.

Advanced Functions

Wireless Mode
With the AF540FGZ, you can take photographs with the flash unit separated from the camera wirelessly in P-TTL mode. Combine the flash unit with the built-in flash unit of the camera or another AF540FGZ attached to the camera. The AF360FGZ can be used interchangeably with AF540FGZ flash units for wireless mode photography. Before photographing, confirm the following. 1. Whether your camera supports this function. Cameras that Support Wireless Mode (page 63) 2. Whether you can use this function with the combination of your camera and the flash mode you have set. Functions Related to Each Flash Mode (page 64 - 71) 3. Whether the slave mode is set to SL1. Slave Mode Setting (page 52)
Notes on Wireless Flash Control (P-TTL photography)
When using the AF540FGZ in wireless mode, the following information is transferred between the flash units attached to the camera and separated from the camera, before the flash units are discharged. Shutter release button is fully pressed. The flash attached to the camera emits a small control flash (relays the flash mode of the camera). The external AF540FGZ emits a pre-flash (verifies the state of the subject). The flash attached to the camera emits a small control flash (relays the flash output amount to the external AF540FGZ). The flash attached to the camera will emit a preflash once more after this to relay the flash duration time when HS (high-speed sync) is set. The external AF540FGZ discharges the main flash (where both flash units discharge main flashes, refer to page 44).
Control Flash and Main Flash The purpose of the control flash of the wireless mode is to send information to the other flash unit before taking a picture. The main flash discharges at the actual time a picture is taken in the same manner as traditionally done. When setting up a flash unit separately from the camera, use the off-camera shoe adapter F when using a tripod, or the off-camera shoe clip CL-10 when setting up in another location such as tabletop, chair, etc. Keep the distance from the built-in flash unit and AF540FGZ to the subject within 4 meters.
Using the AF540FGZ in Combination with a Built-in Flash Unit

Setting switch

The AF540FGZ can be used in combination with a built-in flash unit only when used with the following cameras. *ist D, *ist, MZ-S, MZ-L/ZX-L/MZ-6, K10D (NOTE), K20D, K200D (NOTE) However, this requires the firmware to be updated to Version 1.10 or later. Download the firmware for the K10D from the following URL, and install it on your camera. http://www.pentax.jp/english/support/download_digital.html You may also contact your nearest PENTAX service center for firmware updates. (This will involve a fee.)
Firstly, set the wireless mode and channel of the AF540FGZ, and register them on the camera. Turn the camera off and then attach the AF540FGZ to the hot shoe of the camera. Set the power switch of the flash unit to (WIRELESS). Press the wireless mode button (M/C/S) the number of times required to display SLAVE on the LCD panel. You cannot set the flash unit to SLAVE while the exposure metering timer is on (while information relating to aperture etc. is displayed in the viewfinder). Slide down the setting switch to the (yellow dot) to display the channel on the LCD panel. Press the channel button (CH) and select a channel from 1CH to 4CH. Slide the setting switch back up to the (white dot). When you turn the camera on and press the shutter release button halfway down, the channel is registered on the camera.
Next, remove the flash unit from the camera and place it in the desired position. Press the flash mode button (MODE) to display (P-TTL) if the flash mode was set to the modes other than P-TTL auto.
Enable the built-in flash unit of the camera and set the camera flash mode to (WIRELESS).
Confirm that the AF540FGZ and built-in flash unit are fully charged, and take the photograph. A lamp on the AF540FGZ will blink. In the P-TTL mode, flash output setting (1/1, 2/3, 1/2, and 1/3) and flash output compensation (-3.0 to +1.0) are possible. (Refer to page 18.) The flash mode on the camera must be set to (WIRELESS), otherwise the AF540FGZ will not discharge. By changing the camera's function settings, you can set the built-in flash unit so that it is not the main flash. Refer to the operating manual for the camera to find out how. For test flash, refer to page 58.

Slave Mode Setting

To properly control the slave flash, it is necessary to set the slave mode settings.
Slide the setting switch up. Press the LCD panel illumination button (LIGHT) for 2 seconds or more. SL1 will be displayed. Press the select button (S) to select SL 1 or SL 2. SL 1: When photographing in wireless mode SL 2: When photographing with slave flash

2 seconds or more

The flash will not discharge properly if the slave mode was set to the wrong mode. It may not discharge at all or may discharge simultaneously with the control flash. Press the LCD panel illumination button (LIGHT) to finish setting. In SL 2, fluorescent lamps flicker may contribute to flash units erroneous firing on rare occasions.
Slow-Speed Sync Photography
When using a normal flash to photograph a subject in a night or evening setting, the background will appear very dark because a normal flash light cannot sufficiently light it. However, it is possible to balance both subject and background by using the flash to properly expose the foreground subject and a slow shutter speed to expose the low light background. Before photographing, confirm the following. 1. Whether your camera support this function Cameras that Support Slow-Speed Sync Mode (page 64) 2. Whether you can use this function with the combination of your camera and the flash mode you have set. Functions Related to Each Flash Mode (page 64 - 71) Refer to the camera operation manual for details.

Bounce Flash

With the AF540FGZ, you can tilt and swivel the flash head to aim at the ceiling or wall to bounce the flash before it reaches the subject. Doing so creates softer light and shadows to make the picture look more natural. Bouncing the flash will decrease the flash intensity by the time it reaches the subject. Therefore, this function is effective when photographing in P-TTL or TTL mode at short distances.
The bounce angle can be set to the following angles. Rightward: 0, 30, 60, 90, 120, 150, 180 Leftward: 0, 30, 60, 90, 135 Upward: 0, 30, 45, 60, 75, 90 Downward: 0, -10
A click stop is provided for each bounce angle. Hold the bounce lock release button and tilt the flash head downward when you set the bounce angle at -10. When using bounce flash, ( ) will be displayed on the LCD panel. The effective flash range will blink only when the bounce angle is set at -10. It is recommended to set the bounce angle at -10 to prevent uneven exposure when the distance to the subject is within 1m.

When setting up the flash unit separately from the camera, use the off-camera shoe adapter F when using a tripod, or the optional off-camera shoe clip CL-10 when setting up in another location such as tabletop, chair, etc. The off-camera shoe adapter F cannot be attached to the bundled stand.
