Installing the nano-SIM Card and the microSDXC™ Card (Optional)

Both the nano-SIM card and the microSDXC card can be installed or removed while the device is turned on. You need to unmount the microSDXC card before removing it. See Using the microSDXC Card as

Portable or Device Storage.

WARNING!

To avoid damage to the device, do not use any other kind of SIM cards, or any non-standard nano-SIM card cut from a SIM card. You can get a standard nano-SIM card from your service provider.

1. Insert the tip of the tray

eject tool into the hole on the card tray.

2. Pull out the card tray

and place the nano-SIM card and the optional microSDXC card on the tray, as shown. Carefully slide the tray back into place.

Charging the Battery

Your tablet’s battery should have enough power for the tablet to turn on and find a signal. 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. The status bar at the top of the screen will show the exact battery level.

WARNING!

Use only ZTE-approved chargers and USB Type-C cables. The use of unapproved accessories could damage your device or cause the battery to explode.

WARNING!

Do not remove the back cover. The battery is not removable. Removal may cause fire or explosion.

1. Connect the adapter to the

charging jack.

2. Connect the charger to a

standard AC power outlet. If the tablet is on, you’ll see a

charging icon, such as

or , appear in the status bar.

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 device even when it is being charged. In this case, try again after charging the device for at least 20 minutes. Contact customer service if you still cannot power on the device after prolonged charging.

Note on Smart Battery Protection Mode

Smart Battery Protection mode automatically optimizes the charging mode of the high-density battery in the device based on the device’s usage history in order to prolong the life of the battery.

 Device plugged in for less than 24 hours: Battery will be in active

charging mode.

 Device plugged in for 24 hours: Device will stop charging and enter

standby mode. The battery will start to slowly discharge to 50% (which can take up to a few days depending on background processes of apps and the system.)

 Device remains plugged in after battery has discharged to 50%: Device

will alternate between charging and standby mode, maintaining a battery level of between 50% and 70%.

If the device charging cable is removed and plugged back in, the 24-hour timer resets and the battery will remain in an active charging state for another 24 hours before entering standby mode again.

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 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.

 Use the power saver feature.

Powering Your Tablet On/Off

 Press and hold the Power key to turn on your tablet.  To turn it off, press and hold the Power key to open the options menu.
