To charge the phone, connect the adapter provided in the box to any outlet in your home.
Connect the other end of the power supply to the phone's connector to charge the battery, DC 5V (12).
If the phone is off, it will start up, provided it has enough charge to do so. The battery icon will appear in the icon bar on the screen, showing the battery status.
Important charging notice:
To fully charge the battery, charge it for 7 hours. The indicator light, located on the top right of the phone, will be red if it's charging, and green if the battery is fully charged.
Afterwards, charging the phone overnight will be sufficient to keep the battery charged.
To extend the battery's life, it's recommended not to leave the phone charging for long periods (holidays, etc.). It's better for the battery to be fully discharged occasionally.
If the phone is not used for a long time, remove the battery.
If the battery has not been used for a prolonged period or is depleted, the phone's screen may not work when you charge it again. Once the battery has been charging for a while, you can turn on the phone to use it.
Low battery warning:
When the battery is about to run out, the low battery icon, which appears in the icon bar on the screen, will be empty and the phone will emit a warning tone. You must connect the power supply to charge the battery. If the phone's battery is out of charge, it will turn off and you will not be able to make or receive calls.
