Setting Up Your Phone

The nano-SIM card(s) can be installed or removed while

the phone is turned on.

WARNING!

To avoid damage to the phone, 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.

CAUTION:

Never replace the included tray eject tool with sharp

objects. Ensure that the tray eject tool is perpendicular to

the hole. Otherwise, the phone may be damaged.

2. Pull out the card tray. You can place a nano-SIM card

on the right card slot, and place a nano-SIM card or a

microSDXC card (optional) on the left card slot, as

shown. Carefully slide the tray back into place.

NOTE:

The two card slots support 5G/4G/3G/2G networks.

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 Type-C

cables. The use of unapproved accessories could

damage your phone 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.

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.

Powering On/Off Your Phone

Make sure the battery is charged before powering on.

Press and hold the Power key to turn on your phone.

To power off, press and hold the Power key to open

the options menu, and touch >.

NOTE:

Never text while driving.

Keep your phone at least 5 mm away from your

body while making calls.

Small parts may cause choking.

Your phone can produce a loud sound.

To prevent possible hearing damage, do not

listen at high volume levels for long periods.

Exercise caution when holding your phone near

your ear while the loudspeaker is in use.

Avoid contact with anything magnetic.

Keep away from pacemakers and other

electronic medical devices.

Turn off when asked to in hospitals and medical

facilities.

Turn off when told to on aircraft and at airports.

Turn off when near explosive materials or

liquids.

Don’t use at gas stations.

Your phone may produce a bright or flashing

light.

Don’t dispose of your phone in fire.

Avoid extreme temperatures.

Avoid contact with liquids. Keep your phone

Do not attempt to disassemble your phone.

Only use approved accessories.

For pluggable equipment, the socket-outlet

shall be installed near the equipment and shall

be easily accessible.

Don’t rely on your phone as a primary device

for emergency communications.

Specific Absorption Rate (SAR)

Your mobile device is a radio transmitter and receiver. It

is designed not to exceed the limits for exposure to radio

waves recommended by international guidelines. These

guidelines were developed by the independent scientific

organization ICNIRP and include safety margins

designed to assure the protection of all persons,

regardless of age and health.

The guidelines use a unit of measurement known as

Specific Absorption Rate, or SAR. The SAR limit for

mobile devices is

1.6

W/kg and the highest SAR value for

this device

when tested at the head was

1.169

W/kg*,

and

when tested at the body was

0.589

W/kg*

with

mm distance. As mobile devices offer a range of

functions, they can be used in other positions, such as on

the body as

described in the user manual**.

As SAR is measured utilizing the device’s highest

transmitting power, the actual SAR of this device while

operating is typically below that indicated above. This is

due to automatic changes to the power level of the device

to ensure it only uses the minimum power required to

communicate with the network.

* The tests are carried out in accordance with

IEEE

1528-2013, ANSI C95.1:1992, IEEE C95.1:1991.

** Please see body worn operation

in the user manual.
