REVERSE FUNCTION
The reverse function exchanges a separate reception
and transmission frequency. So, while using a repeater,
you can manually check the strength of a signal that you
receive directly from the other station. If the station’s
signal is strong, both stations should move to a simplex
frequency and free up the repeater.
To swap the transmission and reception frequencies:
Press [REV] to switch the Reverse function ON (or OFF).
• “R” appears when the function is ON.
Note:
◆ You can turn the Reverse function ON when you are operating in
Simplex Mode. However, it does not change the Transmission/
Reception frequencies.
◆ If pressing [REV] places the reception frequency outside the
allowable range, an error tone sounds and the function does not
operate.
◆ If pressing [REV] places the transmission frequency outside the
allowable range, pressing Mic [PTT] causes an error tone to
sound and transmission is inhibited.
◆ You cannot switch Reverse ON or OFF while transmitting.
AUTOMATIC SIMPLEX CHECK (ASC)
While using a repeater, the ASC function periodically
checks the strength of the signal you are receiving from
the other station. If the station’s signal is strong enough
to allow direct contact without a repeater, the
“ ” indicator
starts blinking.
Press [REV] (1s) to switch the function ON (or OFF).
• “ ” appears when the function is ON.
• While direct contact is possible, “ ” blinks.
