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
