Troubleshooting
Your correspondent can not hear you
Increase handset volume.
●●Check that handset cable is securely connected to the phone.
Battery duration in standby mode is too short
Battery standby duration is related to network configuration. You may be in a weak
signal area. If the phone can not receive signals, it will keep sending a signal to search
network and consume additional power, which shortens battery duration.
Battery needs to be changed
If the battery cannot charge properly.
●● Make sure power cord is properly connected to efficiently charge.
●● Clean charging contact from the device and battery with a clean, dry cloth.
●● Replace the battery or charger if it seems to be damaged.
If the above guidelines do not help in solving the problem, note model and serial numbers
of your phone, your warranty details and a clear description of the problem. Then contact
with your after-sales service provider.
