Mobile Power Connections; Mobile Speakers - Yaesu FT-2980R Operating Manual

Mobile Power Connections

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's fuse - it is there to protect you, your transceiver, and your vehicle's electrical
system.
Never apply AC power to the power cable of the FT-2980R, nor DC voltage
greater than 15.8 Volts. When replacing the fuse, only use a 25-A fuse. Failure
to observe these safety precautions will void the Limited Warranty on this
product.
 Before connecting the transceiver, check the voltage at the battery terminals while
revving the engine. If the voltage exceeds 15 Volts, adjust the vehicle's voltage regu-
lator before proceeding with installation.
 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.
 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.
