PC68XL.qxd 2/25/99 10:07 AM Page 4 REAR VIEW 16. ANT.: Connects antenna cable to transceiver. 17. PA SP: Connects optional external 8-ohm, 4-watt speaker for use as a public address system. To prevent acoustic feedback, separate the microphone from the speaker when operating the PA at high output levels. 18. EXT. SP: Connects an 8-ohm 4-watt speaker to remotely monitor the receiver. When the external speaker is plugged in, the internal speaker is off. 19. POWER: Connects DC power to transceiver.
PC68XL.qxd 2/25/99 10:07 AM Page 5 Installation MOBILE STATION INSTALLATION Plan the location of the transceiver and microphone bracket before beginning installation. 1. Select a location that is convenient for operating the radio, but does not interfere with the driver or passenger. 2. Install bracket with self-tapping screws provided. 3. Connect wiring.
