LCD Backlight Brightness
The SideKar Decoder Edition 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 Decoder Edition , 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
Decoder Edition , it will
start at the last brightness selected.
Voltage Check
To display the power supply voltage of the SideKar Decoder
Edition , press Alt-V . The current approximate voltage and the
SideKar Decoder Edition serial number will display. Press Esc
on the keyboard to quit and return to the real-time receiving
mode.
The SideKar Decoder Edition will automatically check the
voltage periodically, and if at or below the low voltage
threshold (~7 volts), will display a low voltage warning screen.
