Your correspondent cannot reach you

Your correspondent cannot hear you speaking

The standby duration is too short
• The standby duration is related to the network settings. You may be in a weak signal area. If your phone cannot receive signals,
the phone will continue to send signals to search for a base station and consume power, which shortens the standby duration. Use
your phone in a stronger signal area or switch o temporarily.
• Your battery needs to be changed.
The battery does not charge properly
• Be sure the cables and plug is well connected.
• Wipe the charging contacts both on the phone and on the battery with a clean soft cloth.
• Change your charging environment if above 10°C or below 40°C.
• Change a damaged battery or charger.
• If the above guidelines do not help you to solve the problem, take note of the model and serial numbers of your phone, your
warranty details, and a clear description of the problem. Then contact your local after-sales service.
