CARE AND MAINTENANCE
Your unit is a technically advanced product and should be treated with the greatest care.
Negligence may void the warranty.
• Protect the unit from moisture. Rain, snow, humidity, and all types of liquids can
contain substances that corrode the electronic circuits. If the unit gets wet, you
should immediately power off the phone, remove the battery and allow the unit to dry
completely before you replace it.
• Do not use or keep the unit in dusty, dirty environments. The unit’s moving parts and
electronic components can be damaged.
• Do not keep the unit in warm places. High temperatures can reduce the lifespan for
electronic equipment, damage batteries and distort or melt certain plastics.

condensation can form on the inside and can damage the electronic circuits.
