SWAPPING THE OPERATING DATA BETWEEN
MAIN BAND AND SUB BAND
There two independent receivers in this transceiver, such
as the main band and the sub band. These two receivers
can behave separately; hence, you can configure different
frequencies and modes for each band. If there is only
one key available for the main band and sub band, you
can operate the transceiver with the key by swapping the
operating band for the main band and sub band.
The frequency displayed on the left side of the main
screen is the main band, and the one on the right side is
the sub band.
[SUB>] [<MAIN]
[HI/SHIFT LO/WIDTH]
1 Press [<MAIN] or [SUB>] to select the band to
operate.
• Frequency display for the band to operate will be larger in
the main screen.
• Main Band: The "MAIN" LED lights green.
• Sub Band: The "SUB" LED lights green.
Note:
◆ The "HIGH/SHIFT LOW/WIDTH" (Sub) LED turns Off upon
selection of the main band, and lights orange upon selection of the
sub band so as to prevent fault operation.
ADJUSTING THE AF GAIN
You can adjust the speaker volume. Two independent AF
controls are available for the main band and for the sub
band, respectively.
[AF](M)
[MUTE](M)
[AF](S)
[MUTE](S)
1 Rotate the AF (M) or AF (S) control.
• Clockwise increases the volume and counterclockwise
decreases it.
Note:
◆ Depending on the configurations for Squelch and CTCSS, no audio
sounds even with a rotation of the AF control. In such a case, rotate
the SQL control counterclockwise or deactivate the CTCSS.
MUTING THE RECEIVED AUDIO
You can mute the received audio with a simple key press,
rather than by rotating the AF control. You can press
[MUTE] for the main band and the sub band respectively.
For example, if you are receiving on both the main band
and the sub band, but would like to concentrate on
listening to the received audio of the station calling on the
main band, you can temporarily mute the sub band.
1 Press [MUTE] (M) or [MUTE] (S) to mute the received
audio.
• The "MUTE" (M) or "MUTE" (S) LED light orange.
• Press again to make the received signal audible.
