■ 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 [A•
FUNC
], then push [4•
DUP
] 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. 45).

TONE
] to activate the subaudible
tone encoder, according to repeater requirements.
• “ ” appears
• Select the desired subaudible 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-
quency shifts. (Transmit frequency shifts in normal duplex mode.)
Each receive and transmit frequency is shown in the table below
with the following conditions;
Inputed freq.: 145.30 MHz
Direction : – (negative) 
Offset frequency : 0.6 MHz
