5 OPERATING THROUGH REPEATERS
14
REVERSE FUNCTION
The reverse function exchanges a separate receive
and transmit 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 transmit and receive 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 TX/
RX frequency.
AUTOMATIC SIMPLEX CHECK (ASC)
While using a repeater, the ASC function periodically
checks the strength of a signal that you are receiving
directly from the other station. If the station’s signal is
strong enough to allow direct contact without a
repeater, “
” indicator on the display starts blinking.
Press
[REV] (1 s)
to switch the function ON.
•
“
” appears when the function is ON.
•
While direct contact is possible, “
” blinks.
•
To quit the function, press
[REV]
.
Note:
◆
Pressing the PTT switch causes “
” icon to quit blinking.
◆
ASC can be activated while operating in Simplex mode.
However, it does not change the TX/ RX frequencies.
◆
ASC does not function while scanning.
◆
Activating ASC while using Reverse switches Reverse OFF.
◆
If you recall a memory channel or the Call channel that
contains a Reverse ON status, ASC is switched OFF.
◆
ASC causes received audio to be momentarily intermitted
every 3 seconds.
◆
ASC does not function when the band is not selected for
operation.
TONE FREQ. ID SCAN
This function scans through all tone frequencies to
identify the incoming tone frequency on a received
signal. You may use the function to find which tone
frequency is required by accessing your local
repeater.
1
While the Tone function is ON, press
[F]
,
[TONE] (1 s)
to start the Tone Freq. ID scan.
•
When the transceiver receives the signal, the
scan starts.
•
To reverse the scan direction, turn the
Tuning
control or press
[ ]
/
[ ]
.
•
To quit the function, press
[PTT]
or
[ ]
.
•
When the tone frequency is identified, a beep
sounds and the identified frequency appears.
2
Press
[ ]
to program the identified frequency in
place of the current tone frequency.
•
Press
[ ]
if you do not want to program the
identified frequency.
•
Press
[ ]
/
[ ]
while the identified frequency is
blinking, to resume scanning.
Note:
Some repeaters do not re-transmit the access tone in the
downlink signal. In this case, check the other station’s uplink
signal to detect the repeater access tone.
