BASIC OPERATION I Channel selection ◊ Channel 16 Channel 16 is the distress and safety channel. It is used for establishing initial contact with another station and for emer- gency communications. Channel 16 is monitored during both dualwatch and tri-watch. While standing by, you must monitor channel 16.

I Call channel programming The call channel switch can be programmed to your most often-used channels in each channel group for quick recall. q While pushing [HI/LO], push [DIAL] one or more times to select the desired channel group (International, U.S.A., Holland, ATIS, DSC) to be programmed.
BASIC OPERATION I Optional voice scrambler operation ◊ Activating the scrambler The optional voice scrambler provides private communica- tions. In order to receive or send scrambled transmissions you must first activate the scrambler function. To activate the function, an optional UT-98 or UT-112 is necessary. See p. 16 for selecting the unit.
I Description Dualwatch monitors channel 16 while you are receiving an- other channel; tri-watch monitors channel 16 and the call channel while receiving another channel. DUALWATCH/TRI-WATCH SIMULATION Dualwatch Tri-watch • If a signal is received on channel 16, dualwatch/tri-watch pauses on channel 16 until the signal disappears.
SCAN OPERATIONS I Scan types Scanning is an efficient way to locate signals quickly over a wide frequency range. The transceiver has priority scan and normal scan. PRIORITY SCAN CH 01 CH 06 CH 16 CH 05 Priority scan searches through all tag channels in se- quence while monitoring channel 16.
I Setting tag channels For more efficient scanning, add desired channels as tag channels or clear tag channels for unwanted channels. Chan- nels set as non-tag channels will be skipped during scanning. Tag channels can be assigned to each channel group (Inter- national, U.S.A., Holland, DSC, ATIS) independently.
SET MODE I Set mode programming Set mode is used to change the conditions of the trans- ceiver’s functions: beep tone function, scan mode (normal/pri- ority), scan resume timer, dual/tri watch, LCD contrast, scram- ble code, scrambler unit, internal speaker and ATIS code. Available functions may differ depending on versions.
I Set mode items ◊ Beep tone You can select silent operation by turning beep tones OFF or you can have confirmation beeps sound at the push of a switch by turning beep tones ON. Set mode Beep Beep tone ON (default) ◊...
