N Repeater operation

When using a repeater, the transmit frequency is shifted from 
the receive frequency by the frequency offset 

(p. 54)

. This is 

called duplex operation. It is convenient to program repeater 
information into memory channels 

(p. 29)

DUP; see p. 26 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.

e  Push and hold [TONE](0) for 1 sec. 

to activate the subaudible tone 
encoder, according to repeater re-
quirements.

• “T” appears.

 

   Refer to p. 53 for tone frequency set-

tings.

rPush and hold [PTT] to transmit.

• The displayed frequency automati-

cally changes to the transmit fre-
quency (repeater input frequency).

• If “OFF” appears, check the frequency 

offset or shift direction. (p. 26)

While receiving

While transmitting

tRelease [PTT] to receive.

y  Push and hold [MONI](BAND) to check whether the other 

station’s transmit signal can be directly received or not.

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