REPEATER OPERATION

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• ] after pushing [A•
DUP
" ."
+
• "–" indicates the transmit frequency is shifted down; "+" indicates
the transmit frequency is shifted up.
• Flashing "–" or "+" indicates the reversed duplex mode is selected
in (p. 46).
SET MODE
• When the auto repeater function is in used (USA version only) this
selection and step e are not necessary. (p. 24)
e
Push [1• ] after pushing [A•
TONE
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

Offset frequency

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

SET MODE
w
Push [Y]/[Z] several times until "±"
and offset frequency appear.
e
Rotate [VOL] to select the desired offset frequency.
• Selectable steps are the same as the pre-set tuning steps.
• The unit of displayed offset frequency is "MHz."

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.
q

"rt" appears.
e
Rotate [VOL] to select the desired subaudible tone.
