Page 5: Introduction
Introduction The FT-250R is an ultra compact FM hand-held providing up to five watts of RF power and a wealth of convenient features for the 2m amateur band. The FT-250R has rubber gasket seals around all external controls and connectors to help keep out dust and rain or spray, assuring years of reliable operation even in harsh environments.

REQUENCY AVIGATION Press the [ VFO ( PRI ) ] button, if necessary, to select the VFO mode. The FT-250R has two VFOs, labeled “A” and “B,” either of which can be used for all of the procedures described in this manual. You can change VFOs with the [ VFO ( PRI ) ] button at any time.
Page 12: Repeater Operation
EPEATER PERATION The ARS (Automatic Repeater Shift) feature in the FT-250R provides repeater shift of the transmit frequency whenever you are tuned to a standard repeater subband (see dia- gram below). When enabled, a small “–” or “+” will be displayed in the upper left-hand corner of the display, signifying that repeater shift is active, and closing the push-to-talk switch changes the display to the (shifted) transmit frequency.
Page 13: Setting Repeater Tx Offset
In order to prevent accidental frequency change or inadvertent transmission, various as- pects of the FT-250R’s DIAL, keypad and switches may be locked out. You may change the lockout combinations. To lock out some or all of the keys: Press the [ F/L ] key, then press the [ 0 ( SET ) ] key to enter the Set mode.

“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”...
Page 15: Tx Battery Saver
ATTERY AVER The FT-250R also includes a useful Transmit Battery Saver, which will automatically lower the power output level when the last signal received was very strong. With the Transmit Battery Saver, the automatic selection of Low Power operation conserves bat- tery drain significantly.
Page 16: Automatic Power-Off (Apo) Feature
ATTERY OLTAGE 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. Rotate the DIAL to select Menu Item #37 (“BATT...

Page 19: Ctcss Operation
T SQ T SQ is active, which mutes your FT-250R’s receiver until it receives a call from another radio sending out a matching CTCSS tone. This can help keep your radio quiet until a specific call is received, which may be helpful while operating in congested areas.

CTCSS/DCS B PERATION During CTCSS Decode or DCS operation, you may set the FT-250R up such that a ring- ing “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.
Page 22: Memory Operation
Memory Operation The FT-250R provides a wide variety of memory system resources. These include: 199 “Standard” memory channels, numbered “1 1 1 1 1 ” through “199 199.” A Home channel, allowing storage and quick recall of one prime frequency.
Page 23: Memory Offset Tuning
UNING Once you have recalled a particular memory channel, you may easily tune off that chan- nel, as though you were in the “VFO” mode. With the FT-250R in the “MR MR” (Memory Recall) mode, select the desired memory channel.
Page 24: Masking Memories
Press and hold the PTT and LAMP key while turning the radio on. Rotate the DIAL to select “MEM.ONLY MEM.ONLY MEM.ONLY MEM.ONLY”. MEM.ONLY Press the [ F/L ] key momentarily to initialize the radio. Repeat the previous step to return to normal operation. FT-250R O PERATING ANUAL...
Page 25: Scanning
Scanning The FT-250R allows you to scan just the memory channels, the entire operating band, or a portion of that band. It will halt on signals encountered, so you can talk to the station(s) on that frequency, if you like.
Page 26: Memory Scanning
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 L1 and U1 Note: Five pairs of Band Limit memories, labeled L1 U1 through L5 U5 are available. L1/U1 L5/U5 FT-250R O PERATING ANUAL...
Page 27: Automatic Lamp Illumination
EEPER The FT-250R will automatically “beep” when a band edge is encountered while tuning. You may disable this feature, if it is annoying, without disabling the keypad beeper (the default condition for this feature is “ON”).
Page 28: Setting The Smart Search Mode
HANNEL CANNING ATCH 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-select- able 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”...
Page 29 Press the [ F/L ] key, then press and hold in the [ VFO ( PRI ) ] key. The FT-250R will now periodically change from the VFO-A frequency to the VFO-B frequency, checking for activity on VFO-B for 0.2 second.
Page 30: Dtmf Operation
Press the numerical key ( [ 1 ] through [ 9 ] ) corresponding to the DTMF memory string you wish to send. Once the string begins, you may release the PTT key, as the trans- mitter will be held “on the air” until the DTMF string is completed. FT-250R O PERATING ANUAL...

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-avail- able connectors wired to your TNC. You may also build your own cable using a four- conductor miniature phone plug, per the diagram below.
Page 35: Cloning
The FT-250R includes a convenient “Clone” feature, which allows the memory and con- figuration data from one transceiver to be transferred to another FT-250R. This can be particularly useful when configuring a number of transceivers for a public service opera- tion.
