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.
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 reducing guesswork in setting the squelch threshold.

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 accessible, 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 visually 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 procedures.

Installation
DC power supply
Fuse holder
Fuse holder
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 providing 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.
r Connect 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.
