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.
