Battery Life
Battery life on a full charge is generally up to 20 hours. This
can vary depending on the applications used, backlight
usage, and radio usage.
Battery packs last approximately 1,000 to 3,000 charging
cycles before they need to be replaced. This is impacted by
applications and environmental factors.
Depending on the current charge on the battery, you may
see different displays when turning on the unit. If the battery
is completely discharged, you will see the following image.
The Archer 3 is designed to run in either of two power states,
battery power, or external power with battery installed.
The unit is not designed to run on external power without a
battery. Doing so can damage internal components of your
unit and void the warranty.
Summary of Options to Reduce Power Usage
You can adjust some settings to preserve power:
„
Turn off the display (suspend) after a set interval.
„
Dim the backlight after a set interval.
„
