Knowing the Keys

Installing the micro-SIM Card and Battery

Switch off your phone before installing or replacing the battery or the SIM card.

1. Insert your fingernail into the slot at the bottom left of the back

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.

3. Align the back cover with the back of the phone and press the cover back into place. Make sure all the tabs are secure and there are no gaps around the cover.

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

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.

2. Connect the charger to a standard AC wall outlet. If the phone is on, you’ll see a charging icon, such as or , appear on the status bar.

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.  Disable the GPS function when not in use. Most applications

using this function will periodically query the GPS satellites for your current location; each query drains your battery.

 Press and hold the Power Key to turn on your phone.  To turn it off, press and hold the Power Key to open the

options menu. Touch Power off and then touch OK.

pressing and holding the Power Key to open the options menu. Touch Restart and then touch OK.

Protecting Your Phone With Encryption

You can encrypt all the data on your phone: Google Accounts, application data, music and other media, downloaded information, and so on. If you do, you must enter a numeric PIN or a password each time you power on your phone.

WARNING! Encryption is irreversible. The only way to revert to

an unencrypted phone is to perform a factory data reset which erases all your data.

Encryption provides additional protection in case your phone is stolen and may be required or recommended in some organizations. Consult your system administrator before turning it on. In many cases the PIN or password you set for encryption is controlled by the system administrator.

Before turning on encryption, prepare as follows:

 Set a lock screen PIN or password.  Charge the battery.  Keep the phone connected to the charger.  Schedule an hour or more for the encryption process. You

must not interrupt it or you will lose some or all of your data.

When you're ready to turn on encryption:

1. Touch the Home Key > Menu Key > System settings > Security > Encrypt phone.

2. Read the information about encryption carefully. The Encrypt phone button is dimmed if your battery is not

charged or your phone is not plugged in. If you change your mind about encrypting your phone, touch

the Back Key. WARNING! If you interrupt the encryption process, you will

lose data.

3. Touch Encrypt phone.

4. Enter your lock screen PIN or password and touch Next.

5. Touch Encrypt phone again. The encryption process starts and displays its progress.

Encryption can take an hour or more, during which time your phone may restart several times.

When encryption is completed, you're prompted to enter your PIN or password.

Subsequently you must enter your PIN or password each time you power on your phone in order to decrypt it.
