4. Battery Information and Care:
Only use the supplied charger. Use of an unauthorized charger may damage the phone and invalidate the
warranty.
Charge the battery promptly when it is flat.
Charge the battery between 0°C~50°C. If the temperature of the handset is too high, switch it off and let it cool.
If the battery is not fully charged after 5 hours charging, please stop charging.
Do not connect the battery directly to an electrical outlet or cigarette lighter charger.
Stop using the battery if abnormal heat, odour, discolouration, deformation, or abnormal condition is detected
during use, charge, or storage.
Keep the battery’s metal contacts clean.
Do not leave a loose battery in your pocket or handbag where metal objects could short the terminals. This could
be a fire or injury hazard.
Battery life can be maximized by regularly allowing the phone to fully discharge before recharging the battery.
When the battery voltage is low the phone will alert and may have limited functionality.
