■Tone squelch operation

Tone squelch operation is a method of communica- tions using selective calling. Only received signals having a matching tone will open the squelch. Before communicating using tone squelch, all members of your party must agree on the tone squelch frequency to use.

➀Push [MODE] one or more times to select FM mode.

➁Push and hold [DISPLAY] to enter Quick Set mode.

➂Push [MENU] one or more times to select item Q7

TONE SQL.

•[Y]/[Z] or [M-CH] can also be used.

➃Rotate the main dial to select the desired subaudi- ble tone frequency.

•Available tone frequencies are the same as for repeater tone operation (see previous page).

Q7 TONE SQL

Set the tone frequency (quick set mode).

See p. 49 for setting de- tails and available fre- quencies.

➄Select M4 and turn the tone squelch function ON.

➥Push [(F-3)TON] to toggle tone squelch opera- tion ON and OFF.

•When tone squelch is turned ON, “TSQL” appears in the display.

➅Communicate in the usual manner.

•Push [PTT] to transmit; release to receive.

■Tone scan operation

By monitoring a signal that is being transmitted on a repeater input frequency, you can determine the tone frequency necessary to open a repeater.

➀During tone squelch or repeater operation, push and hold [DISPLAY] to enter Quick Set mode.

➁Push [MENU] one or more times to select item Q8 T-SQL SCN during tone squelch operation, or

Q8 RPTR-T SCN during repeater operation.

•[Y]/[Z] or [M-CH] can also be used.

➂Push [(F-3)SCN] to toggle tone scan operation ON and OFF.

•While scanning tone frequencies are displayed instead of the operating frequency.

•When a matched tone is detected, tone scan automati- cally stops, the matched tone is displayed and the repeater tone (or tone squelch tone) setting is automat- ically adjusted accordingly.

➃Push [DISPLAY] to return to the main menu.
