Charging the Phone
Your phone's battery should have enough power for
the phone to turn on, find a signal, and make a few
calls. You should fully charge the battery as soon as
possible.
WARNING!
Use only ZTE-approved chargers and USB cables.
The use of unapproved accessories could damage
your phone or cause the battery to explode.
1. Connect the adapter to the charging jack.
Ensure that the adapter is inserted in the correct
direction.
2. Connect the charger to a standard AC power
outlet.
3. Disconnect the charger when the battery is fully
charged.
NOTE:
If the battery is extremely low, you may be unable to
power on the phone even when it is being charged.
In this case, try again after charging the phone for
at least 20 minutes. Contact the customer service if
you still cannot power on the phone after prolonged
charging.
