AUTOMATIC MODE SELECTION
Every Amateur band is subject to frequency
allocations plans commonly referred to as Band
Plans. Following these Band Plans helps reduce
interference between stations that want to use
different modulation modes on the same band.
Automatic Mode is a function that automatically
selects the correct mode according to these plans.
For example, if you are currently operating FM and
then move to a frequency that is in the SSB section of
the band, your transceiver mode automatically
changes to the SSB mode.
Automatic Mode is enabled by selecting AUTO with
[AUTO/FM]. You can always override the automatic
selection if you want by pressing either [AUTO/FM] or
[SSB/CW]. Automatic Mode does not work when
changing frequency while using the Receiver
Incremental Tuning (RIT) function.
There is a separate function available that allows you
to re-program the boundaries for Automatic Mode.
Refer to "REPROGRAMMING AUTO MODE"
{page 38} for further information on this function.

4 COMMUNICATION
SELECTING OUTPUT POWER
It's wise, and required by law, to select the lowest
transmit power that allows reliable communication. If
operating from battery power, lower transmit power
will give you more operating time before a charge is
necessary. Reducing power lowers the risk of
interfering with others on the band too. It is possible
to change output power while transmitting.
Press [LOW] to select the transmit power you require.
* Default: High power (no indicator visible)
• Each press of [LOW] toggles the output power
between High and Low ("LOW")
High ^ Low ("LOW")
Model: High
