Getting to Know Your Phone
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.
- Insert the tip of the tray eject tool into the hole on the card tray.
- 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.
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.
- Connect the adapter to the charging jack.
- Connect the charger to a standard AC power outlet.
- 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:
If the screen freezes or takes too long to respond, try pressing and holding
the Power key for over 10 seconds to restart the phone.
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 15 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.
