379SUBAUDIBLE TONES9■ Tone scanBy monitoring a signal on a repeater, or using pocket beep ortone squelch function, you can determine the tone frequencynecessary to access a repeater or open the squelch.q Set the frequency to be checked for a tone frequency orcode.w Push [A• FUNC ], then push [1• TONE].• Repeat several times to select the type of tone to be scanned.(One of “ ,” “ ” or “ ” appears)• Tone scan may be used even if the tone condition or type is notselected.e Push [A• FUNC ], then push [3• T. SCAN ] to start the tonescan.• To change the scanning direction, push [YY] or [ZZ].r When the CTCSS tone frequency or DTCS code ismatched, the squelch opens and the tone frequency orcode is temporarily programmed into the selected modesuch as 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.- No indication : Cannot be used for operation.- “ ” : CTCSS tone encoder- “ ” : CTCSS tone encoder/decoder- “ ” : DTCS tone encoder/decodert Push [D• CLR ] to stop the scan.DPush FUNCAT.SCAN3Push FUNCATONE1D
