Battery life of the Corsa Digital Compass is
dependent upon usage, but it should average
approximately 500 hours. The battery should
be changed when the display is dim or blank
or when the backlight flickers (backlight only
available in model X473). Using the backlight
drains significantly more power than the
compass alone. Therefore, to maximize battery
life, use the backlight only when necessary.
The Corsa Digital Compass uses one lithium
coin cell battery (3-volt), #2032. These can
be found at most major retailers that carry
batteries. Removal requires the use of a small
Phillips screwdriver (PH 1 or #1 Phillips).
Steps to change the battery
1. Place the compass on a solid surface with
the display facing down.
2. Hold the compass firmly and completely
remove all four screws from the case rear.
3. Remove the case rear and set aside. This
exposes the printed circuit board (PCB)
and the battery. Do not disturb the rubber
seal that is resting on the case front.
4. Remove the battery. Do not remove the
PCB; it is held in place with friction pins
and must be left in the case front to
maintain proper alignment with other
