10.14 PA/FOG OPERATION

The GX5500S has a 30W Hailer built-in and can be used with any 4 Ohm PA Horns. Standard Horizon offers a small and a large PA horn called the 220SW and 240SW. When in Hail mode the PA speaker Listen’s Back (acts as a microphone and sends sound to the front panel speaker and the speaker mic) through the PA horn speaker which provides two-way communications through the PA horn speaker.

NOTE

When in PA or FOG mode the GX5500S will receive on the last selected VHF channel before entering into the PA or FOG mode and receive DSC calls.

NOTE

in some areas powerful AM Broadcast stations may be heard when in listen back mode. In this case the speaker wire will have to be changed to 2 conductor Shielded audio cable available from Radio Shack part number 278-514. refer to section “8.3 ACCESSORY CABLE.”

PA HAIL mode:

PA HAIL mode allows the transceiver to be used as a power hailer when an optional STANDARD HORIZON 220SW or 240SW HAIL/PA speaker is in- stalled. The Hail mode has a listen-back feature which provides two way communication through the HAIL/PA speaker.

FOG HORN mode:

Automatic signaling is transmitted through the HAIL/PA speaker. When the Fog horn, Bells or Whistle signal is not being outputted the GX5500S listens back through the connected PA Horn speaker.
