REPEATER AND DUPLEX OPERATIONS

■ Repeater operation

When using a repeater, the transmit frequency is shifted
from the receive frequency by the offset frequency.
This is called duplex operation. It is convenient to program
repeater information into memory channels.
Repeater
144.700 MHz
145.300 MHz
Station A
q Set the receive frequency
w Set the shift direction of the transmit frequency.
+DUP; see p. 31 for details.)
• When the auto repeater function is in use (U.S.A. version only),
this selection and step e are not necessary. (p. 32)
"–DUP"or "+DUP" appears.

(–DUP or
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. 121 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.

Auto repeater function uses standard values of the re-
peater tone frequency and offset frequency.
