Recommendations should help to uphold warranty claims.
Keep the device in a dry place. Precipitation, dampness and all types of fluids or wet
conditions may contain minerals which corrode electric circuitry.
Do not keep or use the device in dusty or dirty surroundings. The moveable parts and
electronic components could be damaged.
Do not keep the device in hot conditions. High temperatures can shorten the life of
electric devices and deform or melt certain plastics.
Do not keep the device in cold conditions. Internal dampness can build up and damage
the electric circuitry when the device then is moved to normal temperature conditions.

Do not let the device fall, be hit or bumped and do not shake it. Rough handling can
damage electronic circuitry and mechanical parts.
Do not use any harsh chemicals, cleaning solvents or strong cleaning agents to clean
the device.
