Mobile Power Connections
To minimize voltage drop and avoid blowing the vehicle’s fuses, connect the 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-10SR, nor DC voltage greater
than 15.8 Volts. When replacing the fuse, use only a 5-A fuse. Failure to observe
these safety precautions will void the Limited Warranty on this product.
U
Before connecting the transceiver, check the voltage at the battery terminals while rev-
ving the engine. If the voltage exceeds 15 Volts, repair the vehicle’s voltage regulator
before proceeding with installation.
U
Connect the
WHITE
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.
U
Before connecting the cable to the transceiver, verify the voltage and polarity of the
voltage at the transceiver end of the DC cable using a DC voltmeter. Now connect the
transceiver to the DC cable.
