Registering Scan Groups
The Central System emits a free-signal to indicate a MARITEX
radio channel is in idle condition and available for ship-to-shore
calls. The free-signal is detected and recognized by the shipboard
equipment as a permission to start the transmission. Then, the ship-
board operator initiates a call.
You can scan search for the free-signal automatically by register-
ing MARITEX radio channels in scan group(s). The procedure for
registering scan groups for MARITEX use is the same as that which
appears on page 3-7.
1. Press function key [F5] to display the Station menu.
