Device Maintenance

Handle your device and accessories with care. The following suggestions help you keep your device operational.

  • Keep the device dry. Humidity, and all types of liquids or moisture can contain minerals that corrode electronic circuits.

  • Do not use or store the device in dusty or dirty areas.

  • Do not store the device in high temperatures. High temperatures may damage the device.

  • Do not store the device in cold temperatures. When the device warms to its normal temperature, moisture can form inside the device and damage it.

  • Do not attempt to disassemble the device. The warranty is not valid, if the device has been disassembled.

  • Unauthorized modifications may damage the device.

  • Do not drop, knock, or shake the device. Rough handling can break it.

  • Only use a soft, clean, dry cloth to wipe the surface of the device.

  • Keep the device away from magnets or magnetic fields.

Cleaning the Optics

Occasionally, the device lens needs cleaning. Use compressed air to blow out any dirt from the device lens. The compressed air must be clean and bottled; otherwise oil or water may end up on the lens.


Only use oil and moisture-free compressed air in a spray can for the device lens.


Do not use excessive air pressure to clean up the device lens.

If you want to wipe the device lens, to remove greasy stains, use isopropanol alcohol.

Proceed as follows:

  1. Wipe the device lens to remove the dirt.
