LCD Backlight Brightness
The SideKar Extreme LCD backlight brightness is adjustable in
7 levels. When operating using a battery, it is wise to minimize
the current usage (but you already knew that), and this feature
helps you do so. The display is transflective, so backlighting is
probably not needed at all when outdoors, even on a cloudy
day.
In the SideKar Extreme, the first 4 levels are a group that are
lower brightness levels, and more appropriate for running on a
battery. The remaining 3 higher levels are more suitable when
not running on a battery.
To adjust the brightness, press
Alt-B
. Each press of
Alt-B
will
go to the next level of brightness, from off to bright.
The brightness selected is remembered in EEPROM, so the
next time you turn on the SideKar Extreme, it will start at the
last brightness selected.
Voltage Check
To display the power supply voltage of the SideKar Extreme,
press
Alt-V
. The current approximate voltage and the SideKar
Extreme serial number will display. Press Esc on the keyboard
to quit and return to the real-time receiving mode.
The SideKar Extreme will automatically check the voltage
periodically, and if at or below the low voltage threshold (~7
volts), will display a low voltage warning screen.
