Connecting to a Hailer Horn or PA Speaker
You can connect the radio to a hailer horn or public address (PA) speaker (not
included) to use the microphone or the handset to make announcements.
1
If necessary, mount the hailer horn or PA speaker according to the
installation instructions provided with the device.
NOTE: To avoid feedback, you should mount the hailer horn or PA
speaker at least 3 m (10 ft) away from, and facing away from, the
microphone or handset.
2
Route or extend the wire from the hailer horn or PA speaker to the radio.
3
Connect the white wire on the radio wiring harness to the positive (+) wire
from the hailer horn or PA speaker.
4
Connect the green wire on the radio wiring harness to the negative (-) wire
from the hailer horn or PA speaker.
5
Cover the connections with a waterproof tape or heat-shrink tubing.
Connecting to an External Speaker
You can connect the radio to an external speaker (not included) to hear the
radio at a remote location.
1
If necessary, mount the speaker according to the installation instructions
provided with the device.
2
Route or extend the wire from the speaker to the radio.
3
Connect the red wire on the radio wiring harness to the positive (+) wire
from the speaker.
4
Connect the black wire on the radio wiring harness to the negative (-) wire
from the speaker.
5
Cover the connections with a waterproof tape or heat-shrink tubing.
