FTM-3100R/E Operating Manual
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.
Warning!
Never apply AC power to the power cable of the FTM-3100R/E, nor DC voltage
greater than 15.8 Volts. When replacing the fuse, only use a 25-A (20-A,
European version) fuse. Failure to observe these safety precautions will void
the Limited Warranty on this product.
r
Before connecting the transceiver, check the voltage at the battery terminals while rev-
ving the engine. If the voltage exceeds 15 Volts, adjust the vehicle’s voltage regulator
before proceeding with installation.
r
Connect the
RED
power cable lead to the
POSITIVE
(
+
) battery 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.
r
Before connecting the cable to the transceiver, verify the voltage and polarity at the
voltage at the transceiver end of the DC cable, using a DC voltmeter. Now connect the
transceiver to the DC cable.

Warning!
•
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
