428POCKET BEEP AND TONE SQUELCH8■ Tone scanBy monitoring a signal using with pocket beep, tone or DTCSsquelch, you can determine the tone frequency or DTCScode necessary to open the squelch.q Set the desired operating frequency or memory channel tobe checked for a tone frequency or code.• Push [MAIN] to select the desired band (left or right) as the mainband in advance.w Push and hold [MONI•T/T-SCAN] for 1 sec and rotate themain band’s [DIAL] to select the tone type, tone squelch orDTCS, to be 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 the main band’s [DIAL].r When the CTCSS tone frequency or 3-digit DTCS code ismatched, the squelch opens and the tone frequency istemporarily programmed into the VFO or 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 Or push any key for the main band or any of the sharedkeys below the display to stop the scan.NOTE: The decoded tone frequency is programmed tem-porarily when a memory is selected. However, this will bereplaced by the programmed information when the mem-ory channel is re-selected.[MONI•T/T-SCAN]During CTCSS frequency scan During DTCS code scan
