SELECTING A CHANNEL/FREQUENCY
■
Selecting a channel
The transceiver has 160 user channels and ITU chan-
nels. However, the number of user channels can be
optionally restricted and ITU channels are not available
with some versions.
☞
NOTE:
When channel 0 and/or 2182 kHz is se-
lected with the [2182KHz] switch, channel selection
is NOT possible. In such cases, push [2182KHz] in
advance.

Using the channel selector
The transceiver has two large controls for group se-
lection and channel selection. The [GROUP] selector
changes channels in 20 channel increments and se-
lects ITU channel groups*; and the [CHANNEL] se-
lector selects each channel.
➀
Make sure no “
s
” indicator appears on the display.
➁
Rotate the [GROUP] selector to select the desired
channel group as shown at right and/or below.
➂
Rotate the [CHANNEL] selector to select the de-
sired channel.
[EXAMPLE]:
Selection with the [GROUP] selector
