it USING SET MODE'CSS tones)for tone squelch oper-;ame range of tones isones, these are set inde .TS_QL1 1 1-1#1 07i i= 111_1, 1one and exit set mode .ory mode:Tone scanThe transceiver can detect the subaudible tone frequency in areceived signal . By monitoring a signal, such as that beingtransmitted on a repeater input frequency, you can determinethe tone frequency required to access the repeater.O Set the desired frequency or memory channel to bechecked for a tone frequency.OO Push [a (T-SCAN)] for 1 sec. to start the tone scan ." Push ["]/["] to change the scan direction.03 When the tone frequency is decoded, the set mode con-tents are programmed with the tone frequency." The decoded tone frequency is used for the tone encoder or toneencoder/decoder, depending on the tone squelch on/off setting." "Ct" (CTCSS-Continuous Tone Coded Squelch System) or °Rt"(Repeater Subaudible Tone) appears during tone scan whetherthe tone squelch is in use or not.® Push [v (T-SCAN)] again to stop the scan .SUBAUDIBLE TONE OPERATION" Pocket beep operationThis function uses subaudible tones for calling and can beused as a "common pager" to inform you that someone hascalled you while you were away from the transceiver.T Set the operating frequency.02 Set the desired subaudible tone (same as that used fortone squelch operation, "Ct") in set mode ." See previous page for programming .Os Push [c T] two times until "TSQL (( " )) " appears.® When a signal with a matched tone is received, the trans-ceiver emits-beep tones for 30 sec. and flashes "(I " i) ."OO Push [PTT] to answer or push [ 4 ] to stop the beeps andflashing ." Tone squelch is automatically selected .O Calling a waiting station using pocket beepA subaudible tone matched with the station's tone frequencyis necessary.
