Battery Replacement
The XR-3 includes a replaceable Li-Ion rechargeable battery. When the battery wears out in the
future, battery replacement is simple.
Required Tools:
1x #2 Phillips screwdriver
1x Safety glasses
Estimated completion time: 5 +/- minutes, depending on mechanical aptitude and proficiency
Battery replacement procedure:
1) Wear safety glasses
2) Stand instrument upright on solid stable surface
3) Unfasten flap's Velcro from rear of module body and fold flap downwards
4) Loosen (2) thumb screws until they fall out of the (2) threaded dowel pins on top of
instrument
5) Remove (2) threaded dowel pins by pushing them gently from the middle of the unit
outwards
6) Remove module by grasping the top, first pulling outwards and then upwards
7) Remove each rubber shock guard by gently pulling the top of each outwards. You will
notice that the plugs in the middle of each rubber shock guard will pop out of place as
you pull. Pull shock guards downward, taking care to slowly remove both rubber shock
guards from base unit while keeping the flap axle attached between them. Use caution
so that the flap axle doesn't pop out and cause injury to an eye or other body part.

other soft fabric under the unit to protect the display from getting scratched.
