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 – terminals of the battery. Short-circuiting
the terminals may damage the battery or the connecting
object.
Do not dispose of the battery in a fire.
Phone Maintenance
Your device is a product of superior design and chairmanship and
should be treated with care. The suggestions below will help you
protect your warranty coverage.
Keep the phone and all the parts and accessories (for example,
SIM 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.
