8-168 SCANS■ Tone scan The receiver can detect subaudible tones or the DTCScode in a received signal. By monitoring a signal that isbeing operated with tone or DTCS squelch function,you can determine the tone frequency or DTCS codenecessary to open a squelch.q Set the desired frequency or memory channel to bechecked for a tone frequency.w Push [FM] to select FM mode.e Push and hold [TONE] for 1 sec. to enter tone fre-quency screen.r Push [F-1•Y] or [F-2•Z] to check the tone squelchfrequency or DTCS code, respectively.t Push [F-6•T-SCAN] to start the tone scan.• “SCAN” blinks while scanning.y When the tone frequency is detected, the tone scanpauses.• The tone frequency is set temporarily on a memorychannel. Program into the memory channel to store thetone frequency permanently.• The decoded tone frequency is used for the tonesquelch frequency or DTCS squelch code.u To stop the scan, push [F-6•T-SCAN].• Push and hold [F-4•DEF] for 1 sec. to select the defaultfrequency.i Push [EXIT/SET] to exit tone frequency screen.[EXIT/SET][FM][TONE][F-1•Y] [F-2•Z] [F-6•T-SCAN][F-4•DEF]
