Cleaning the XTR39
For safety reasons, disconnect the battery before cleaning.
- On the exterior surface, wipe gently using a damp cloth and then try the surface.
- On the LCD screen, wipe gently using a soft cloth. It is recommended to use an optical type
cleaning cloth.
- The contacts that engage the docking cradle should remain free of dirt and debris. With the
unit disconnected from power, clean the contacts using a dry cloth or cotton swab.
Do not use solvents or other chemicals.
Doing so will damage the XTR39.
