Vertex Standard FTM-10R manual Mobile Power Connections, Mobile Speakers

INSTALLATION

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 fuse - it is there to protect you, your transceiver, and your vehicle's electrical sys- tem.

Warning!

Never apply AC power to the power cable of the FTM-10R, nor DC voltage greater than 15.8 Volts. When replacing the fuse, use only a 15-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 rev- ving the engine. If the voltage exceeds 15 Volts, repair the vehicle’s voltage regulator 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.
