U.S.A. and Korean versions:
The auto repeater function has priority over the manual duplex
setting. If the transmit frequency changes after setting, the
auto repeater function may have changed the duplex setting.
Turn the auto repeater function OFF to prevent this (p. 27).
■
Reverse duplex function
When the reverse duplex function is ON, the receive and
transmit frequencies are reversed. The function can be set in
the Set mode.
q
Push
