Allow only qualified personnel to service your
phone
Allowing unqualified personnel to service your phone
may result in damage to your phone and will void your
manufacturer's warranty.
Ensure maximum battery and charger life
•
Avoid charging batteries for more than a week, as
overcharging may shorten battery life.
•
Over time, unused batteries will discharge and must
be recharged before use.
•
Disconnect chargers from power sources when not
in use.
•
Use batteries only for their intended purpose.
Handle SIM cards or memory cards with care
•
Do not remove a card while the phone is transferring
or accessing information, as this could result in loss
of data and/or damage to the card or phone.
•
Protect cards from strong shocks, static electricity,
and electrical noise from other devices.
•
Do not touch gold-coloured contacts or terminals
with your fingers or metal objects. If dirty, wipe the
card with a soft cloth.
