REPEATER OPERATION

■ Accessing a repeater

q Set the receive frequency (repeater output frequency) on

the main band. (pgs. ??–??)

w Push [DUP•MONI] one or two times, to select minus du-

plex or plus duplex.

• “DUP–” or “DUP+” appears to indicate the transmit frequency for

minus shift or plus shift, respectively.

• When the auto repeater function is turned ON (available for the

USA version only), steps w and e are not necessary. (p. ??)

e Push [TONE•DTMF] several times to turn ON the subaudi-

ble tone encoder, according to repeater requirements.

• “TONE” appears 
• 88.5 Hz is set as the default; refer to p. ?? for tone frequency set-

tings.

• When the repeater requires a different tone system, see p. ??.

r Push and hold [PTT] to transmit.

• The displayed frequency automatically changes to the transmit

frequency (repeater input frequency).

• If “OFF” appears, confirm that the offset frequency (p. ??) is set

correctly.

t Release [PTT] to receive.

y Push [DUP•MONI] to check whether the other station’s

transmit signal can be received directly.

u To return to simplex operation, push [DUP•MONI] once or

twice, to clear the “DUP–” or “DUP+” indicator.

i To turn OFF the subaudible tone encoder, push

[TONE•DTMF] several times until no tone indicators ap-
pear.
