2 INSTALLATION AND CONNECTIONS ■ Battery connections RWARNING! • N EVER connect to a battery without supplying a DC fuse, otherwise a fire hazard occurs. • NEVER connect the transceiver directly to a 24 V battery. The transceiver may not receive well on some frequencies when installed in a hybrid vehicle, or any type of electric vehicle (fuel cell vehicle). This is because vehicle's electric components such as the inverter system generate a lot of electric noise. CONNECTING A VEHICLE BATTERY  • DO NOT use a cigarette lighter socket as a power source when operating in a vehicle. The plug may cause voltage drops and ignition noise may be superimposed onto transmit or receive audio. • Use a rubber grommet when passing the DC power cable through a metal plate to prevent a short circuit. IMPORTANT! D etailed installation notes for Icom mobile transceivers to be fitted into vehicles are available. Contact your Icom dealer or distributor. black NOTE: Use terminals for the cable connections. 2 red Crimp Grommet 12 V battery Supplied DC power cable Solder ■ External antenna tuners CONNECTING THE AH-4 Transceiver ANT1 Coaxial cable (from the AH-4) AH-4 Long wire or optional AH-2b Ground Ground CONNECTING THE AT-180 [ACC] Transceiver ACC cable supplied with the AT-180 Coaxial cable supplied with the AT-180 [ANT1] [ANT] AT-180 [ACC] HF to 6 m antenna Either of the two external connectors Ground [TRANSCEIVER] Ground • Turn the IC-7000's power OFF when connecting the AT-180, otherwise, the CPU may malfunction and the AT-180 may not function properly. • The OPC-742 is required when using both the AT-180 and a 2m/70cm linear amplifier. Do not connect [ANT2] to the AT180. When using an HF to 2m/70cm dual or wide-band antenna, use a duplexer between the AT-180 and antenna since 2 m/70 cm signals do not pass through the AT-180.
