5910 POCKET BEEP AND TONE SQUELCH Tone scanBy monitoring a signal that is being operated with pocketbeep, tone or DTCS squelch function, you can determine thetone frequency or DTCS code necessary to open a squelch.q Set the desired operating frequency or memory channel tobe checked for a tone frequency or code.w Push [TONE•T-SCAN] several times to select the type oftone, tone squelch or DTCS, to be scanned.• Either “T SQL” or “DTCS” appearse Push [TONE•T-SCAN] for 1 sec. to start the tone scan.• To change the scanning direction, rotate [DIAL].r When the CTCSS tone frequency or 3-digit DTCS code ismatched, the squelch opens and the tone frequency istemporarily programmed into the selected condition suchas memory or call channel.• The tone scan pauses when a CTCSS tone frequency or 3-digitDTCS code is detected.• The decoded CTCSS tone frequency or 3-digit DTCS code isused for the tone encoder or tone encoder/decoder dependingon the selected tone condition or type in step w.- “T SQL” : CTCSS tone encoder/decoder- “DTCS” : DTCS tone encoder/decodert Push [TONE•T-SCAN] to stop the scan.z Set the frequency or memory channel to bechecked for a tone frequency.x Selects the tone type to be scanned.• Push [FUNC] then push; [ SIMP 9(TSQL)] for tonesquelch; [HIGH 4(DTCS)] for DTCS squelch.c Push [FUNC] then [SCAN 2(T-SCAN)] to startthe tone scan.v When the tone frequency is matched, thesquelch opens and the tone frequency is pro-grammed into the selected mode such asmemory or call channel.b Push [CLR A(MW)] to stop the scan.NOTE: The decoded tone frequency is programmed temporar-ily when a memory or call channel is selected. However, thiswill be cleared when the memory/call channel is re-selected.T-SCANDuring CTCSS frequency scan During DTCS code scan[TONE•T-SCAN]
