14
cover and lift it up gently.
2. Hold the SIM card with the cut corner oriented as shown and
slip it into the card holder.

15
3. Align the back cover with the back of the phone and press the

Installing the microSDHC™ Card
The microSDHC card can be installed and removed while the
phone is turned on. Unmount the microSDHC card before
removing it.
1. Remove the back cover.
2. Hold your microSDHC card with the metal contacts facing
down and slide it in.
NOTE: Some applications may require a microSDHC card to
work normally or may store certain data on it. Therefore, it is
recommended that you keep a microSDHC card installed and

16
not remove or replace it randomly.
3. Replace the back cover.
Charging the Battery
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.
If the battery is low, there will be a pop-up message on the
screen. As you charge your phone, the screen will tell you the
exact battery level each time you wake up your phone.
WARNING! Use only ZTE-approved chargers and 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 with the correct orientation. Do not force
the connector into the charging jack.

17

3. Disconnect the charger when the battery is fully charged.
Extending the Battery Life
Active applications, screen brightness levels, Bluetooth and Wi-Fi
usage and GPS functionality can drain your battery. You can
follow the helpful tips below to conserve your battery power:
Reduce the screen backlight time.
Lower the screen brightness.
Turn auto-sync, Wi-Fi, and Bluetooth off when not in use.
