■ Subaudible tonesSome repeaters require subaudible tones to be accessed.Subaudible tones are superimposed over your normal signaland must be set in advance.qPush [A• FUNC ], then push [8• SET] to enter SET MODE.wPush [YY] or [ZZ] one or more times until “rt” appears.e Rotate [VOL] to select the desired subaudible tone.rPush [✱•ENT ] (or [D• CLR ]) to fix the selected tone andexit SET MODE.• Available subaudible tone frequencies (unit: Hz)DD Tone informationSome repeaters require another tone system to be accessed.DTMF TONESWhile pushing [PTT], push the desired DTMF keys (0–9,[A• FUNC ], [B• CALL ], [C• MR ], [D• CLR ], [#• BANK ] and[✱•ENT ]) to transmit DTMF tones.• [✱•ENT ] transmits as “E”, [#• BANK ] transmits as “F.”• The transceiver has 16 DTMF memory channels (p. 26).1750 Hz TONEWhile pushing [PTT], push [YY] or [ZZ] to transmit a 1750 Hztone signal.✔ ConvenientTone scan function: When you don’t know the subaudibletone used for a repeater, the tone scan is convenient for de-tecting the tone frequency.Push [A• FUNC ], then push [3• T.SCAN ] to start the tone scan.• Push [D• CLR ] to cancel the scan.• When the required tone frequency is detected, the scanpauses.67.069.371.974.477.085.488.591.594.897.4100.0103.579.782.5107.2110.9114.8118.8123.0127.3131.8136.5141.3146.2151.4156.7159.8162.2165.5167.9171.3173.8177.3179.9183.5186.2189.9192.8196.6199.5203.5206.5210.7218.1225.7229.1233.6241.8250.3254.1USING SET MODE185 REPEATER OPERATION
