Advanced Operation

VFO SPLIT MODE
For working on repeaters with odd splits, or communicating with astronauts on orbiting space vehicles, it may be necessary to use non-standard splits between the receive and transmit frequency. If the application is infrequent enough not to warrant the dedication of a memory channel for this purpose, the VFO Split mode may be used. Here is the procedure: Press the [VFO(PRI)] key, as needed, to select VFO-A. Set VFO-A for the receiving frequency (for example, 144.950 MHz). Now press the [VFO(PRI)] key, and set VFO-B for the desired transmit frequency (e.g. 144.750 MHz). Press the [VFO(PRI)] key once more to re-establish VFO-A as the Main (receive) VFO. Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode. Rotate the DIAL to select Menu #5 (V-SPLIT V-SPLIT). V-SPLIT Press the [F/L] key, then rotate the DIAL to set this function ON. Press the PTT key once to save the new setting and exit to normal operation. You will now be operating in a Split mode. When you press the PTT key to transmit, you will observe that VFO-A and VFO-B will reverse positions.The VFO selection indicator b will blinks while the transceiver is transmitting, this means that the VFO b Split feature is now activated. If you need to modify the VFO-B (transmit) frequency (for Doppler Shift correction, etc.), just press the [VFO(PRI)] key, then make the necessary change, then press [VFO(PRI)] key once more to restore VFO-A to the receive VFO position. When you have finished with Split operation, re-enter the Set mode, and set Menu #5 to OFF. A split frequency pair set up via the VFO Split feature cannot be stored directly into memory. You can, however, store odd frequency pairs using a different (slightly simpler) procedure. See page 18.
RECEIVE BATTERY SAVER SETUP
An important feature of the FT-250R is its Receive Battery Saver, which puts the radio to sleep for a time interval, periodically waking it up to check for activity. If somebody is talking on the channel, the FT-250R will remain in the active mode, then resume its sleep cycles. This feature significantly reduces quiescent battery drain, and you may change the amount of sleep time between activity checks using the Menu System: Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. Rotate the DIAL to select Menu Item #9 (RX SAVE RX SAVE). Press the [F/L] key to enable adjustment of this Menu item.
Rotate the DIAL to select the desired Sleep duration. The selections available are 200 ms, 300 ms, 500 ms, 1 second, and 2 seconds, or OFF. The default value is 200 ms. When you have made your selection, press the PTT key to save the new setting and exit to normal operation. When you are operating on Packet, switch the Receive Battery Saver OFF, as the sleep cycle may collide with the beginning of an incoming Packet transmission, causing your TNC not to receive the full data burst. Likewise, during voice operation, part of the first word of an incoming transmission may be cut off during (normal) Battery Saver operation.

CHECKING THE BATTERY VOLTAGE
The FT-250R is capable of measuring the current battery voltage. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. BATT Rotate the DIAL to select Menu Item #37 (BATT BATT). [F/L] key to check the battery voltage. Press the To return to normal operation, press the [F/L] key, then press the PTT.
DISABLING THE BUSY/TX LED
Further battery conservation may be accomplished by disabling the BUSY/TX LED. Use the following procedure: Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. Rotate the DIAL to select Menu Item #12 (TRX LED TRX LED). [F/L] key to enable adjustment of this Menu item. Press the Rotate the DIAL to set this Menu item to OFF (thus disabling the BUSY/TX LED). Press the PTT key to save the new setting and exit to normal operation.
BUSY CHANNEL LOCK-OUT (BCLO)
The BCLO feature prevents the radios transmitter from being activated if a signal strong enough to break through the Noise squelch is present. The default setting for the BCLO is OFF, and here is how to change that setting: Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. BCLO Rotate the DIAL to select Menu Item #23 (BCLO BCLO). [F/L] key to enable adjustment of this Menu item. Press the Rotate the DIAL to set the BCLO feature to the ON position. Press the PTT key to save the new setting and resume normal operation.
DISABLING THE KEYPAD BEEPER
If the keypads Beeper creates an inconvenience, it may easily be disabled. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. Rotate the DIAL to select Menu Item #16 (KEY BP KEY BP). [F/L] key to enable adjustment of this Menu item. Press the Rotate the DIAL to change the setting from ON to OFF. When you have made your selection, press the PTT key to save the new setting and exit to normal operation.
PROGRAMMING THE KEY FUNCTIONS
Default FT-250R set mode have been assigned (at the factory) to the [7(P1)] and [8(P2)] keys. These may be changed by the user, if you wish to define another set mode for a keys. To change the assignment of a keys set mode: Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode. Rotate the DIAL knob to click through the menu in search of the desired function. Press and hold in the [F/L] key for one second, then press the [7(P1)] or [8(P2)] key to be assigned. Press the PTT key to save the new setting and exit to the set mode.
TRANSMITTER TIME-OUT TIMER (TOT)
The TOT feature provides a safety switch which limits transmission to a pre-programmed maximum duration. This will promote battery conservation by not allowing you to make excessively-long transmissions, and in the event of a stuck PTT switch (perhaps if the radio or a Speaker/Mic is wedged between car seats) it can prevent interference to other users as well as battery depletion. As configured at the factory the TOT feature is set to OFF, and here is the procedure for activating it: Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. Rotate the DIAL to select Menu Item #22 (TOT TOT). TOT Press the [F/L] key to enable adjustment of this Menu item. Rotate the DIAL to set the Time-Out Timer to the desired Maximum TX time (1 minute, 2.5 minutes, 5 minutes, or 10 minutes). Once youve made the selection you wish to use, press the PTT key to save the new setting and exit to normal operation.

DCS OPERATION

Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more advanced tone system which generally provides more immunity from false paging than does CTCSS. The DCS Encoder/Decoder is built into your FT-250R, and operation is very similar to that just described for CTCSS. Your repeater system may be configured for DCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use transceivers equipped with this advanced feature. Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and that you select a tone code. Press the [F/L] key, then immediately press the [1(SQ TYP)] key. This provides a SQL TYP). Short-cut to Menu #25 (SQL TYP Rotate the DIAL until DCS appears on the display; this activates the DCS Encoder/ DCS DCS Decoder. When you have made your selection of the DCS mode, press the PTT key. Press the [F/L] key, then immediately press the [2(CODE)] key. This provides a Shortcut to Menu #27 (DCS SET DCS SET). Rotate the DIAL to select the desired DCS Code (a three-digit number). Ask the repeater owner/operator if you dont know DCS Code; if you are working simplex, just set up the DCS Code to be the same as that used by your friend(s). When you have made your selection, press the [F/L] key to save the new settings and exit to normal operation. Remember that the DCS is an Encode/Decode system, so your receiver will remain muted until a matching DCS code is received on an incoming transmission. Switch the DCS off when youre just tuning around the band!

DCS CODE

TONE SEARCH SCANNING In operating situations where you dont know the CTCSS or DCS tone being used by another station or stations, you can command the radio to listen to the incoming signal and scan in search of the tone being used. Two things must be remembered in this regard: You must be sure that your repeater uses the same tone type (CTCSS vs. DCS). Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s) transmitting on the repeater uplink (input) frequency in order to allow Tone Search Scanning to work.
To scan for the tone in use:
Set the radio up for either CTCSS or DCS Decoder operation (see the previous discussion). In the case of CTCSS, T SQ will appear on the display; in the case of DCS, T SQ DCS will appear on the display. DCS DCS Press the [F/L] key, then immediately press the [2(CODE)] key to select the TN SET TN SET Menu item (when TONE SQL is selected) or DCS SET (during DCS operation). DCS SET Press the [F/L] key, then press and hold in the [ (MHz)] or [ (MHz)] key to start scanning for the incoming CTCSS or DCS tone/code. When the radio detects the correct tone or code, it will halt on that tone/code, and audio will be allowed to pass. Press the [F/L] key to lock in that tone/code. Press the [F/L] key, then press the PTT key to save the new settings and exit to normal operation. If the Tone Scan feature does not detect a tone or code, it will continue to scan indefinitely. When this happens, it may be that the other station is not sending any tone. You can press the PTT switch to halt the scan at any time. You also can press the MONI key during Tone Scanning to listen to the (muted) signal from the other station. When you release the MONI key, Tone Scanning will resume after about a second.

CTCSS/DCS BELL OPERATION

During CTCSS Decode or DCS operation, you may set the FT-250R up such that a ringing Bell sound alerts you to the fact that a call is coming in. Here is the procedure for activating the Bell will ring in accordance with this programming. Set the transceiver up for CTCSS Decode (TONE SQL) or DCS operation, as described previously. Adjust the operating frequency to the desired channel. Press the [F/L] key, then press the [0(SET)] key to activate the Set mode. Rotate the DIAL to select Menu Item #18 (BELL BELL). BELL Press the [F/L] key to enable adjustment of the Bell ringer. Rotate the DIAL to set the desired number of rings of the Bell. The available choices are 1, 3, 5, or 8 rings, REPEAT (continuous ringing), or OFF. Press the PTT key momentarily to save the new setting and exit to normal operation. When a station calls you whose transceiver is sending a CTCSS tone or DCS code which matches that set into your Decoder, the Bell will ring in accordance to this programming.

Memory Operation

The FT-250R provides a wide variety of memory system resources. These include: 199 Standard memory channels, numbered 1 through 199 199. A Home channel, allowing storage and quick recall of one prime frequency. Five sets of band-edge memories also known as Programming Memory Scan channels, labeled L1 U1 through L5 U5 L1/U1 L5/U5 L1 U1 L5 U5

MEMORY STORAGE

Select the desired frequency, while operating in the VFO mode. Be sure to set up any desired CTCSS or DCS tones, as well as any desired repeater offset. Press and hold in the [MR/MW(SKIP)] key for one second. Within five seconds of releasing the [MR/MW(SKIP)] key, rotate the DIAL to select the desired memory channel number. Press the [MR/MW(SKIP)] key once more to store the frequency into memory. You still will be operating in the VFO mode, so you may now enter other frequencies, and store them into additional memory locations, by repeating the above process.
STORING INDEPENDENT TRANSMIT FREQUENCIES (ODD SPLITS)
All memories can store an independent transmit frequency, for operation on repeaters with non-standard shift. To do this: Store the receive frequency using the method already described under MEMORY STORAGE (it doesnt matter if a repeater offset is active). Turn to the desired transmit frequency, then press and hold the [MR/MW(SKIP)] key for one second. Within five seconds of releasing the [MR/MW(SKIP)] key, rotate the DIAL to select the same memory channel number as used in step above. Press and hold the PTT switch. Then while holding the PTT switch in, momentarily press the [MR/MW(SKIP)] key once more (this does not key the transmitter). Whenever you recall a memory which contains independently-stored transmit and receive frequencies, the [][+] indication will appear in the display. The Odd Splits feature permits setting TONE/DCS individually for transmit and receive. Briefly, press the [F/L] key, and then press the [2(CODE)] key. Rotate the DIAL knob to select the TONE or DCS for receive. You can confirm the Transmit and receive TONE/DCS by alternately pressing of the [REV(HOME)] key.

MEMORY RECALL

While operating in the VFO mode, press the [MR/MW(SKIP)] key. The MR indicaMR MR tor will show that you are now in the Memory Recall mode. Rotate the DIAL to select the desired channel. To return to the VFO mode, press the [VFO(PRI)] key. An easy way to recall memories is to key in the memory channel number, then press [MR/MW(SKIP)]. For example, to recall memory channel #16, press [1]-[6]-[MR/MW(SKIP)].

MEMORY OFFSET TUNING

Once you have recalled a particular memory channel, you may easily tune off that channel, as though you were in the VFO mode. With the FT-250R in the MR (Memory Recall) mode, select the desired memory MR MR channel. Now press the [MR/MW(SKIP)] key momentarily. The MR indicator will be blinking. MR MR Rotate the DIAL, as desired, to tune to a new frequency. The synthesizer steps selected for VFO operation on the current band will be the steps used during Memory Tuning. If you wish to return to the original memory frequency, press the [MR/MW(SKIP)] key momentarily. The MR indication will no longer be blinking. MR MR If you wish to store a new frequency in the current or another memory. Just press and hold the [MR/MW(SKIP)] key for one second, select the new memory channel (if desired), and press [MR/MW(SKIP)] key again momentarily. Any required CTCSS/DCS changes, or repeater offset modifications, must be done before storing the data into the new (or original) memory channel location.

HOME CHANNEL MEMORY

A special one-touch HOME channel is available, allowing quick recall of a favorite operating frequency. Memory storage is simple to accomplish: REV HOME Change the setting of Menu Item #20 from REV to HOME if it is not already set to REV HOME, that option (see page 35). Select the desired frequency, while operating in the VFO mode. Be sure to set up any desired CTCSS or DCS tones, as well as any desired repeater offset. Press and hold the [MR/MW(SKIP)] key for 1/2 second. While the memory channel number is blinking, just press the [REV(HM)] key. The frequency and other data (if any) will now be stored in the special HOME channel register. To recall the HOME channel, press the [REV(HM)] key momentarily while operating in the VFO or MR mode.

LABELING MEMORIES

You may wish to append an alpha-numeric Tag (label) to a memory or memories, to aid in recollection of the channels use (such as a club name, etc.). This is easily accomplished using the Set mode. Recall the memory channel on which you wish to append a label. Press the [F/L] key, then press the [0(SET)] key, to enter the Menu mode. Rotate the DIAL to select Menu #1 (ALPHA ALPHA). ALPHA [F/L] key to enable changing of this Menu item. Press the Press the [F/L] key, then press the [F/L] key again, to begin entry of the Label. Rotate the DIAL to select the first digit of the desired label. When you have made your selection, press the[ (MHz)] key momentarily to move to the next character. Repeat the previous step to program the remaining letters, numbers, or symbols of the

To set the Scan-Resume mode
Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode. Rotate the DIAL to select Menu #7 (RESUME RESUME). RESUME Press the [F/L] key to enable changing of this Menu item. Rotate the DIAL to select the desired scan-resume mode. When you have made your selection, press the PTT key to save the new setting and exit to normal operation. The default condition for this Menu Item is 5 SEC.

VFO SCANNING

This mode allows you to scan the entire current operating band. Select the VFO mode by pressing the [VFO(PRI)] key, if necessary. Press and hold in the [ (MHz)] or [ (MHz)] key for 1/2 second to start scanning. If and when the scanner encounters a signal strong enough to open the squelch, the scanner will halt temporarily; the decimal point of the frequency display will blink during this Pause condition. The scanner will then resume according to the Scan Resume selected in the previous section. To cancel scanning, press the PTT key. If you want to change direction of the scan while it is underway, rotate the DIAL one click in the opposite direction (in this case, one click counter-clockwise).
MEMORY SCANNING Memory scanning is similarly easy to initiate: Set the radio to the Memory mode by pressing the [MR/MW(SKIP)] key, if necessary. Press and hold in the [ (MHz)] / [ (MHz)] key for 1/2 second to initiate scanning. As with VFO scanning, the scanner will halt on any signal encountered that is strong enough to open the squelch; it will then resume scanning according to the Scan-Resume mode set previously. To cancel scanning, press the PTT key. HOW TO SKIP (OMIT) A CHANNEL DURING MEMORY SCAN OPERATION
When you have some very active channels stored in memories, you may wish to skip them when scanning, but still have them available for manual selection. Such channels may be Skipped during scanning, if you like: Set the radio to the Memory Mode by pressing the [MR/MW(SKIP)] key, if necessary. Rotate the DIAL to select the Memory Channel to be skipped during scanning. Press the [F/L] key momentarily (not for 1/2 second), then press the [MR/MW(SKIP)] key (momentarily). A small SKIP will appear to the LCD. indicating it is to be ignored during scanning. To re-institute the channel into the scanning loop, repeat the above three steps (the Skipped channel will, of course, still be accessible via manual channel selection methods using the DIAL in the MR mode).
PROGRAMMABLE (BAND LIMIT) MEMORY SCAN (PMS)
This feature allows you to set sub-band limits for either scanning or manual VFO operation. For example, you might wish to set up a limit (in North America) of 144.300 MHz to 148.000 MHz so as to prevent encroachment into the SSB/CW Weak Signal portion of the band below 144.300 MHz. Heres how to do this: Set the radio to the VFO mode by pressing the [VFO(PRI)] key, if necessary. Using the techniques learned earlier, store (per the above example) 144.300 MHz into Memory Channel #L1 (the L designates the Lower sub-band limit). L1 L Likewise, store 148.000 MHz into Memory Channel #U1 (the U designates the UpU1 U per sub-band limit). Switch to the Memory mode by pressing the [MR/MW(SKIP)] key once, then rotate the DIAL to select Memory Channel # L1 L1. Press the [MR/MW(SKIP)] key; the MR label will be blinking in the left-hand freMR MR quency of the display. You may now rotate the DIAL, or begin scanning by pressing the [ (MHz)] or [ (MHz)] key for 1/2 second. The transceiver will behave as though it is in the standard VFO mode, but operation will be restricted to the range between Memory Channels L1 and U1 U1. Note: Five pairs of Band Limit memories, labeled L1 U1 through L5 U5 are available. L1/U1 L5/U5

Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode. Rotate the DIAL to select Menu #31 (SMT MOD SMT MOD). Press the [F/L] key to enable changing of this Menu item. Rotate the DIAL to select the desired Smart Search mode (see above). When you have made your selection, press the PTT key to save the new setting and exit to normal operation.
Storing Smart Search Memories
Set the radio to the VFO mode. Press the [F/L] key, then press the [8(P2)] key.* Press the [ (MHz)] or [ (MHz)] key to begin the Smart Search scanning. As active channels are detected, you will observe the number of loaded channels increasing in the regular memory channel window. Depending on the mode you set for Smart Search operation (SINGLE or CONTINUE), the Smart Search scan will eventually terminate, and the LCD will revert to Smart Search Memory Channel 0. To recall Smart Search memories, rotate the DIAL to choose from among the Smart Search memories. To return to normal operation, press the [VFO(PRI)] key. * The default function of the [8(P2)] key is Smart Search. If you are changed the [8(P2)] key assignment to another function described previously, Storing Smart Search Memories procedure is following: Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. Rotate the DIAL to select Menu Item #30 (S SRCH S SRCH). Press the [F/L] key, then press the [ (MHz)] or [ (MHz)] key to begin the Smart Search scanning.
PRIORITY CHANNEL SCANNING (DUAL WATCH)
The FT-250R scanning features include a two-channel scanning capability which allows you to operate on a VFO or Memory channel, while periodically checking a user-selectable Priority Channel for activity. Here is the procedure for activating Priority Channel Dual Watch operation:

VFO (or HOME) - Memory

Recall the memory channel you wish to be the Priority Channel. Set the radio to the VFO mode or HOME channel by pressing the [VFO(PRI)] or [REV(HM)] key. Press the [F/L] key momentarily (not for 1/2 second), then press the [VFO(PRI)] key (momentarily). A small PRI notation will appear on the LCD.

Memory-Memory mode

Store a frequency that you want to use as the Dual Watch Priority channel into memory 1. 1 Set the radio to the Memory mode by pressing the [MR/MW(SKIP)] key. Rotate the DIAL to select the channel on which you wish to operate while periodically checking for activity on channel 1 during Dual Watch operation. Press the [F/L] key momentarily (not for 1/2 second), then press the [VFO(PRI)] key (momentarily). A small PRI notation will appear on the LCD.

BASIC ARTS SETUP AND OPERATION
Set your radio and the other radio(s) to the same DCS code number, per the discussion on page 16. Press [F/L] key, then press the [7(P1)] key* to activate the ARTS operation. Press the [F/L] key. You will observe the OUT RNG display on the LCD. ARTS OUT RNG operation has now commenced. Every 15 seconds, your radio will transmit a polling call to the other station. When that station responds with its own ARTS polling signal, the display will change to IN RNG to IN RNG confirm that the other station polling code was received in response to yours. Press the [F/L] key again to exit ARTS operation and resume normal functioning of the transceiver. *The default function of the [7(P1)] is ARTS. If you are changed the [7(P1)] key assignment to another function described previously, ARTS setup and operation procedure is following: Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. Rotate the DIAL to select Menu Item #13 (ARTS ARTS). ARTS Press the [F/L] key twice to active the ARTS operation.
ARTS POLLING TIME OPTIONS
The ARTS feature may be programmed to poll every 15 seconds (default value) or 25 seconds. The default value provides maximum battery conservation, because the polling signal is sent out less frequently. To change the polling interval: Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode. Rotate the DIAL to select Menu #15 (AR ITVL AR ITVL). Press the [F/L] key to enable changing of this Menu item. Rotate the DIAL to select the desired polling interval (15 or 25 seconds). When you have made your selection, press the PTT key to save the new setting and exit to normal operation.

ARTS ALERT BEEP OPTIONS

The ARTS feature allows two kinds of alert beeps (with the additional option of turning them off), so as to alert you to the current status of ARTS operation. Depending on your location and the potential annoyance associated with frequent beeps, you may choose the Beep mode which best suits your needs. The choices are: IN RANGE:The beeps are issued only when the radio first confirms that you are within range, but does not re-confirm with beeps thereafter. ALWAYS: Every time a polling transmission is received from the other station, the alert beeps will be heard. ARB OFF: No alert beeps will be heard; you must look at the display to confirm current ARTS status. To set the ARTS Beep mode, use the following procedure: Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode. Rotate the DIAL to select Menu #14 (ARTS BP ARTS BP). Press the [F/L] key to enable changing of this Menu item. Rotate the DIAL to select the desired ARTS Beep mode (see above). When you have made your selection, press the PTT key to save the new setting and exit to normal operation.

CW IDENTIFIER SETUP

The ARTS feature includes a CW identifier. Every ten minutes during ARTS operation, the radio can be instructed to send DE (your callsign) K if this feature is enabled. The callsign field may contain up to 16 characters. Heres how to program the CW Identifier: Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode. Rotate the DIAL to select Menu #29 (CW ID CW ID). Press the [F/L] key to enable changing of this Menu item.

Press the Rotate the DIAL to set the CW ID function ON. When you have made your selection, press the PTT key to save the new setting and exit to normal operation.
Interface of Packet TNCs & Reset
The FT-250R may be used for Packet operation, using the optional CT-44 microphone adapter (available from your Yaesu dealer) for easy interconnection to commonly-available connectors wired to your TNC. You may also build your own cable using a fourconductor miniature phone plug, per the diagram below. The audio level from the receiver to the TNC may be adjusted by using the VOL knob, as with voice operation. The input level to the FT-250R from the TNC should be adjusted at the TNC side; the optimum input voltage is approximately 5 mV at 2 k-Ohms.

10 F 2 K

SP GND MIC PTT GND
Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent voltage spikes from possibly damaging your transceiver. Also, be certain to turn off the Receiver Battery Saver, if activated (see page 10).

MICROPROCESSOR RESETTING

In the event that erratic, unpredictable transceiver operation is encountered, it is possible that the microprocessor has sustained a static burst or other condition that has caused corruption of some of its data. If this should happen, resetting of the microprocessor should clear up the problem. Here is the procedure for resetting the microprocessor (this will restore all factory defaults, and will erase all memories): Turn the radio off. Press and hold the PTT and LAMP key while turning the radio on. Rotate the DIAL to select ALL.RST on the LCD. ALL.RST ALL.RST Press the [F/L] key momentarily to initialize the radio.
