BASIC OPERATION

I Repeater operation

When using a repeater, the transmit frequency is shifted from
the receive frequency by the offset frequency. (p. 31) It is con-
venient to program repeater information into memory chan-
nels. (p. 37)
434.340 MHz
439.340 MHz
Station A
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 Korea ver-
sions only), this selection and step e are not necessary. (p. 33)
e Push [2 TONE] for 1 sec. to activate the subaudible tone
encoder, according to repeater requirements.
