1998 Nissan Frontier Owner's Manual - Page 101

CB RADIO OR CAR PHONE Microphone installed model If equipped with a genuine cellular phone, your NISSAN features a non-directional microphone in the steering column cover, so it is not necessary to look at or speak directly into the microphone when calling. To do so could detract from the driving operation and cause an accident. See the manual for car phone operation. ● Connect the ground wire from the CB radio chassis to the body. ● For details, consult an authorized NISSAN dealer. Pre-wired and antenna for phone installed model Some models are pre-wired to accept the genuine NISSAN cellular phone. In addition, the same model has the phone antenna built into the rear glass window. When installing a CB, ham radio or car phone in your NISSAN, be sure to observe the following cautions, otherwise the new equipment may adversely affect the MFI (Multiport Fuel Injection) system and other electronic parts. AHA1053 CAUTION ● Keep the antenna as far as possible away from the Engine Control Module. ● Also keep the antenna wire more than 8 inches (20 cm) away from the MFI harness. Do not route the antenna wire next to any harness. ● Adjust the antenna standing-wave ratio as recommended by the manufacturer. 4-22 Heater, air conditioner and audio systems
