REPEATER OPERATION
■
Accessing a repeater
➀
Set the receive frequency (repeater output frequency).
(pgs. 15–17)
➁
Push and hold [
(LOW)
DUP] for 1 sec., one or more times,
to select minus duplex 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
➁
and
➂
are not necessary. (p. 25)
➂
Push [TONE] one or more times to turn ON the subaudi-
ble tone encoder, according to repeater requirements.
• Refer to p. 23 for tone frequency settings.
• When the repeater requires a different tone system, see the next
page.
➃
Push and hold [PTT] to transmit.
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
• The operating condition is automatically programmed into a
scratch pad memory. See p. 34 for details.
• If “OFF” appears, confirm that the offset frequency (p. 34) is set
correctly.
➄
Release [PTT] to receive.
➅
Push [MONI] to check whether the other station’s transmit
signal can be received directly.
➆
To return to simplex operation, push [
(LOW)
DUP] for 1 sec.,
once or twice, to clear the “DUP” indicator.
➇
To turn OFF the subaudible tone encoder, push [TONE]
one or more times until no tone indicators appear.
Ä
Set the receive frequency (repeater output fre-
quency). (p. 15)
Å
Push [
➆
DUP–] to select – duplex; push
[
➇
DUP+] for + duplex.
Ç
Push [FUNC] then [
➆
TONE] to turn ON the sub-
audible tone encoder according to repeater re-
quirements.
• Refer to p. 23 for tone frequency setting.
• When the repeater requires a different tone system,
see next page.
É
Push and hold [PTT] to transmit.
Ñ
Push and hold [
➀
MONI] to check whether the
other station’s signal can be received directly.
Ö
Release [PTT] to receive.
Ü
To return to simplex operation, push [
➈
SIMP].
á
To turn OFF the subaudible tone encoder, push
[FUNC], then [
G
T-OFF].
