(One of “ ,”“ ” or “ ” appears)• Tone scan may be used even if the tone condition or type is not selected.e Push [FUNC], then push [T.SCAN ](3) to start the tone scan.• To change the scanning direction, push [YY] or [ZZ].PushT.SCAN3FUNCAPushTONE1FUNCADr When the CTCSS tone frequency or DTCS codeis matched, the squelch opens and the tone fre-quency or code is temporarily programmed intothe selected mode such as memory or call chan-nel.• The tone scan pauses when a CTCSS tone fre-quency or 3-digit DTCS code is detected.• The decoded CTCSS tone frequency or 3-digit DTCScode is used for the tone encoder or tone encoder/de-coder depending on the selected tone condition ortype in step w.- No indication : Cannot be used for operation.- “ ” : CTCSS tone encoder- “ ” : CTCSS tone encoder/decoder- “ ” : DTCS tone encoder/decodert Push [CLR] to stop the scan.D
