REPEATER OPERATION
■
Offset frequency
When communicating through a repeater, the transmit frequency is
shifted from the receive frequency by an amount determined by the
offset frequency.

e
Rotate [VOL] to select the desired offset frequency.

Subaudible tones
Some repeaters require subaudible tones to be accessed. Sub-
audible tones are superimposed over your normal signal and must
be set in advance.

General
When using a repeater, the transmit frequency is shifted from the
receive frequency by the offset frequency. It is convenient to pro-
gram repeater information into memory channels.
q
Set the receive frequency (repeater output frequency).
w
Push [4•
DUP
] after pushing [A•
FUNC
] several times to select “
–
” or
“
+
.”
• “–” indicates the transmit frequency is shifted down; “+” indicates
the transmit frequency is shifted up.
• Flashing “–” or “+” indicates the reversed duplex mode is selected
in
SET MODE
(p. 46).
• When the auto repeater function is in used (USA version only) this
selection and step
e
are not necessary. (p. 24)
e
Push [1•
TONE
] after pushing [A•
FUNC
] to activate the subaudible
tone encoder, according to repeater requirements.
• “
” appears.
• Select the desired sub audible tone frequency, if necessary. (p. 22)
r
Push and hold [PTT] to transmit.
• The displayed frequency automatically changes to the transmit fre-
quency (repeater input frequency).
• If “OFF” appears, check the offset frequency and direction.
t
Release [PTT] to receive.
y
Push and hold [SQL] to check whether the other station’s trans-
mit signal can be directly received or not.
About reversed duplex mode
When the reversed duplex mode is selected, the receive fre-
quencies shifts. Each receive and transmit frequency are shown
in the table below with the follow conditions; entered freq. : 145.00
