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 con-
tain 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 com-
pletely 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.
• Do not keep the unit in cold places. When the unit warms up to normal temperature,
condensation can form on the inside and can damage the electronic circuits.
• Do not try to open the unit in any other way than that which is indicated here.

terminals.
• Replace the battery only with another battery that has been qualified with the sys-
tem per this standard, IEEE-Std-1725. Use of an unqualified battery may present a
risk of fire, explosion, leakage or other hazard.
