348POCKET BEEP AND TONE SQUELCH8■ 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 and hold [MONI•T/T-SCAN] for 1 sec and rotate[DIAL] to select the tone type, tone squelch or DTCS, tobe scanned.• Either “ ” or “ ” appears.e Push and hold [MONI•T/T-SCAN] for 1 sec. to start thetone 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 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 decoder depending on the selected tone con-dition or type in step w.- “ ” : CTCSS tone decoder- “ ” : DTCS tone decodert Push any switch to stop the scan.NOTE: The decoded tone frequency is programmed tem-porarily when a memory is selected. However, this will becleared when the memory channel is re-selected.During CTCSS frequency scan During DTCS code scan[MONI•T/T-SCAN]
