REPEATER AND DUPLEX OPERATIONS
15-2
■ FM Repeater operation
A repeater receives transmitted signals and retransmits
them on a different frequency. The transmit frequency
is shifted from the receive frequency by a preset fre-
quency offset.
In duplex operation, the transceiver’s frequency offset
is set to the same as that of the repeater. (p. 16-16)
q Push [V/MHz] to select the VFO mode.
w Push [MODE] several times to select the FM
mode.
e Rotate [DIAL] to set the receive frequency (repeater
output frequency).
• The frequency changes according to the preset tuning
steps. See the page 5-8 for details.
Only USA and Korean versions have an Auto Re-
peater function:
When the function is turned ON, steps r and t are
not necessary.*
