Mobile Power ConnectionsTo minimize voltage drop and avoid blowing the vehicle’s fuses, connect the suppliedDC power cable directly to the battery terminals. Do not attempt to defeat or bypass theDC cable’s fuse - it is there to protect you, your transceiver, and your vehicle’s electricalsystem.Warning!Never apply AC power to the power cable of the FT-2980R, nor DC voltagegreater than 15.8 Volts. When replacing the fuse, only use a 25-A fuse. Failureto observe these safety precautions will void the Limited Warranty on thisproduct. Before connecting the transceiver, check the voltage at the battery terminals whilerevving 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 theBLACK power cable lead to the NEGATIVE (–) terminal. If you need to extend thepower cable, use #12 AWG or larger insulated, stranded copper wire. Solder thesplice connections carefully, and wrap the connections thoroughly with insulatingelectrical tape. Before connecting the cable to the transceiver, verify the voltage and polarity of thevoltage at the transceiver end of the DC cable using a DC voltmeter. Now connectthe transceiver to the DC cable.FT-2980RFuse 25 AFuse HolderWARNING!NEVER remove the FUSEholders from the DC cable.Mobile SpeakersThe optional MLS-100 External Speaker includes its own swivel-type mounting bracket,and is available from your Yaesu dealer.Other external speakers may be used with the FT-2980R, if they present the specified4-Ohm impedance and are capable of handling the 3 Watts of audio output supplied bythe FT-2980R.11InstallationFT-2980R Operating Manual
