Leaving the battery in hot or cold place, such as in a closed car in
summer or winter conditions, will reduce the capacity and lifetime of
the battery. A device with a hot or cold battery may not work
temporarily, even when the battery is fully charged. Battery
performance is particularly limited in temperatures well below
freezing.

Do not short-circuit the battery. Accidental short-circuiting can occur
when a metallic object causes a direct connection between the + and

card) out of the reach of small children.
Do not use or store the phone in dusty or dirty locations. Its moving parts
and electronic components can be damaged.
Do not use or store the phone in excessively hot places. High
temperatures will shorten the life-span of the phone, damage the battery,
and warp or melt the plastic used in the phone’s manufacture.
Do not store the phone in excessively cold places. When the phone
returns to its normal temperature, moisture can form inside the phone,
causing damage to the electronic circuits.

can damage the internal circuits.
Do not use harsh chemicals, strong detergents, or cleaning solvents to
clean the phone. If you must clean it, then use a soft, clean and dry
cloth.
