Introduction
Features of this radio
144/430 MHz dual band mobile radio, equipped with a C4FM communication modem.
50 Watts of power output, with selection of three power levels for every operating situ-
ation.
Clear audio and data communication is achieved using the C4FM modem functions.
Expanded receiver coverage: 108.000 MHz - 579.995 MHz.
With the GD-ID (Digital Group ID) feature, the Group Monitor (GM) feature enables au-
tomatically locating, and communicating with other stations that have the same DG-ID
number within contact range, by utilizing a matching group ID number from 00 to 99.
The Digital Personal ID (DP-ID) feature supports communication specifically with
transceivers registered with the individual ID information. The DP-ID is different for
each transceiver and is included in each C4FM transmission.
Easily connect with the WIRES-X linking system.
Keyboard entry of operating frequencies from the microphone.
225 memories (199 “basic” memory channels, 10 sets of band-edge memory channels,
and 6 “Home” channel) which can store repeater shifts, odd repeater shifts, CTCSS/
DCS tones, and 8-character Alpha-Numeric labels for easy channel recognition.
Built-in CTCSS and DCS Encoder/Decoder circuits.
Extensive Menu system, which allows customization of a number of transceiver perfor-
mance characteristics.
Equipped with the GM (Group Monitor) function.
Additional features include a transmit Time-Out-Timer (TOT), Automatic Power-Off (APO),
and Automatic Repeater Shift (ARS). Also included is an RF Squelch circuit that allows
the owner to set the squelch to open at a programmed setting of the S-Meter, thus reduc-
ing guesswork in setting the squelch threshold.
Congratulations on your purchase of the FTM-7250DR! Whether this is your first rig, or if
Yaesu equipment is already the backbone of your station, the Yaesu organization is com-
mitted to ensuring your enjoyment of this high-performance transceiver. It should provide
you with many years of satisfying operation. Our dealer network and technical support
personnel stand behind every product we sell, and we invite you to contact us should you
require technical advice or assistance.
We recommend that you read this manual in its entirety prior to installing the FTM-
7250DR, so that you fully understand the capabilities of your new transceiver.

Mobile Installation
The FTM-7250DR must only be
installed in vehicles having a 13.8
Volt negative ground electrical
system. Mount the transceiver
where the display, controls, and
microphone are easily accessi-
ble, using the supplied mounting
bracket.
The transceiver may be installed
in almost any location, but should
not be positioned near a heating
vent nor anywhere where it might
interfere with driving (either visual-
ly or mechanically).
Make sure to provide plenty of space on all sides of the transceiver so that air can flow
freely around the radio’s case. Refer to the diagrams showing proper installation proce-
dures.

7
Installation
Power connection
To minimize voltage drop and avoid blowing the vehicle’s fuses, connect the supplied
DC power cable directly to the battery terminals. Do not attempt to defeat or bypass the
DC cable fuse - it is there to protect you, your transceiver, and your vehicle’s electrical
system.
Operation of the FTM-7250DR from an AC line requires a power source capable of pro-
viding at least 20 Amps continuously at 13.8 Volts DC. The FP-1023 (USA market only)
and FP-1030A (USA/Asian market only) AC Power Supplies are available from your
Yaesu dealer to satisfy these requirements. Other well-regulated power supplies may be
used as well, if they meet the above voltage and current specifications.
Warning!
• Never apply AC power to the power cable of the FTM-7250DR, nor DC voltage greater
than 15.8 Volts. When replacing the fuse, only use a 15 A fuse. Failure to observe these
safety precautions will void the Limited Warranty on this product.
• Do not use a DC power supply cable other than the one that is supplied or specified.
• Do not place anything on the DC power supply cable or step on it.
• Do not use the DC power supply cable with the fuse holder cut off.
• Do not reverse the polarity (positive and negative) when connecting the battery.
rConnect the RED power cable lead to the POSITIVE (+)terminal, and the BLACK
power cable lead to the NEGATIVE (–)terminal. If you need to extend the power cable,
use #12 AWG or larger insulated, stranded copper wire. Solder the splice connections
carefully, and wrap the connections thoroughly with insulating electrical tape.

The FTM-7250DR transceiver is equipped with the AMS (Automatic Mode Select) func-
tion which automatically selects from two modes of transmission corresponding to the
signal being received.
The transmit mode is selected according to the received signal so that C4FM digital sig-
nals, and analog signals are received and transmitted automatically.
Press [MODE(DG-ID)] key to display “ ” (blinks) icon on the screen.
Display example when in AMS mode
AMS transmission mode
To operate in fixed communication mode, press
[MODE(DG-ID)] key to switch the communication
mode.
Each time [MODE(DG-ID)] key is pressed, the com-
munication mode changes in the following order:
àAMS (“ ” blinks) àV/D (DN) (“ ” lights up) à
àVWø(“ ” lights up) àFM (no icon) à
Communication mode Icon Description of modes
AMS (Automatic Mode Select) (blinks)
Transmit mode is automatically selected from 3
types according to the signal received.
The AMS function operation can be changed
from the Setup menu setting. See “Setting the
transmit mode when using the AMS function
(DIG AMS 12)” on 39
V/D (DN) Mode
(Voice/Data simultaneous
transmission mode)
(light up)
Calls are less prone to interruptions due to de-
tection and correction of voice signals during
digital voice signal transmission. This is the
standard mode for C4FM Digital.
Voice FR (VW) Modeø
(Voice Full Rate mode)
High speed data communication using entire
12.5 kHz band. Enables high-quality voice com-
munication.
Analog FM Mode no icon
Analog communication using FM mode.
Effective when the signal is weak and audio is
susceptible to interruption in digital mode.
ø: When the Setup Menu item “DIG VW 13” is set to “ON” (factory default is “OFF”), the
Voice FR (VW) may be selected.

Basic Operation
Setting the transmission mode when using the AMS function
The AMS function will automatically set the receiver to the mode of the received signal,
but the transmission mode may be fixed regardless of the received mode.
1. Press and hold the [GM(AMS)] key.
2. Rotate the DIAL knob to select the
the desired transmission mode as
follows.
AUTO (“ ” blinks: 0.5 sec of, 0.5 sec off)
Automatically selects one of the two
communication modes according to
the received signal.

Note: When the Setup Menu item “DIG VW 13” is set to “ON” (factory default is “OFF”),
the “TX VWFIX” may be selected.
Automatically selects one of the two
communication modes according to
the received signal. Always switch-
es to VW mode for transmission. Blinks: 0.5 sec on

2. Speak into MIC on the microphone.
Note: Keep the microphone about 5 cm away from your mouth.
The sensitivity (gain) of the microphone can be adjusted, use the Setup Menu
Item “MIC GAIN 25” see 40 for details.
3. Release PTT switch.
The transmit mode/status indicator turns off and the transceiver returns to the receive
mode.
Caution: Do not continue transmitting for a prolonged period. The transceiver may
overheat, resulting in malfunction or injury.
Note: “ERROR” appears if you attempt to transmit on an unavailable frequency.

Basic Operation
Adjusting the transmit power
When communicating with a nearby station, the transmit power level may be reduced to
save on energy consumption.
1. Press the [D]key on the microphone.
2. Rotate the DIAL knob or press the [UP]/[DWN]key
on the microphone to select the transmit power.
Note: The default setting: HIGH

Advanced Operation
About the Digital Group ID (DG-ID) feature
The DG-ID function can set up two-digit DG-ID numbers from “00” to “99” separately for
Transmit and Receive. By setting both transmit and receive to “00” (default), you can
communicate with all the other stations in the digital C4FM mode.
By matching the transmit DG-ID number to the uplink DG-ID number set in the club DR-
2X/XE System Fusion II digital repeater, you can access the digital repeater DR-2X/XE
used in the club.
For communication only among a group of friend’s transceivers, you can all match the
same DG-ID number; then only your friend’s voices will be heard. Also, by using the GM
function you can check whether stations with the same DG-ID are in the communication
range. The FTM-7250DR may register transmit and receive DG-ID numbers in the DG-ID
memories (up to 10 pairs), and then use the [P1]/ [P2]keys on the microphone to easily
recall a Group ID.
