Holding down the

Changing power level .
You can change the transmitter’s power level at any time by pressing the
Power - Increase
or
Power - Decrease
button. This change does not alter the preset’s stored power
level. Instead, you enter a manual editing mode, identified on the status bar as
MAN (in manual
preset mode) or AUT
(if operating in automatic preset scheduler). This text replaces the normal active
preset status text (e.g.,
M-1
for manual or
A-1
).
To make a manually changed power level become part of a preset, enter the appropriate
Preset Edit
page (see Figure 2.7 on page 2-11 ).
The
Power
field is now selectable for editing and is accompanied by an animated arrow and the text
Different
, indicating that there is a difference between the active power level and the preset’s stored
power level.
Press the
Set Power
button to store the current power level into the preset. This changes the preset
parameters, but does not make the preset active.
Changing power preset schedules.
You can program a monthly schedule for the transmitter.
Use the
Power Preset Schedule
page to set the times at which power presets take effect. You can
define a different schedule for each month of the year. To view the
Power Preset Schedule
page,
select
Power Preset Schedule
from the General Settings menu .
