Repeater operation
When using a repeater, the transmit frequency is shifted from
the receive frequency by the offset frequency.
(p. 97)
It is con-
venient to program repeater information into memory chan-
nels.
(p. 66)
q
Set the receive frequency
(repeater output frequency)
.
w
Set the shift direction of the transmit frequency.
(–DUP or
+DUP; see p. 31 for details.)
• When the auto repeater function is in use (U.S.A. and Korean
versions only), this selection and step
e
are not necessary.
(p. 32)
e
Push and hold
[TONE](7)
for 1
sec. to activate the subaudible
tone encoder, according to re-
peater requirements.
• “TONE” appears.
Refer to p. 107 for tone frequency
settings.
r
Push and hold
[PTT]
to transmit.
• The displayed frequency automati-
cally changes to the transmit frequency (repeater input fre-
quency).
• If “OFF” appears, check the offset frequency or shift direction.
(p. 30)
t
Release
[PTT]
to receive.
y
Push and hold
[SQL]
to check whether the other station’s
transmit signal can be directly received or not.
U.S.A. and Korean versions:
Auto repeater function uses standard values of the re-
peater tone frequency and offset frequency.
