Getting to Know Your Phone

Setting Up Your Phone

The nano-SIM cards 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. Obtain 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(s) flatly on either side of the tray. Carefully slide the tray back into place.

NOTES: Please use the tray eject tool included in the box. If two nano-SIM cards are installed, both can connect to the 5G network, and you can use either card for mobile data.

CAUTION: Never replace the included tray eject tool with sharp objects. Ensure the tray eject tool is perpendicular to the hole to avoid damaging the phone. Do not insert the tray eject tool into other holes on the phone.

Charging the Phone

Your phone's battery should have enough power to turn on, find a signal, and make a few calls. Fully charge the battery as soon as possible.

WARNING! Use only nubia-approved chargers and USB Type-C cables. Unapproved accessories could damage your phone or cause the battery to explode. Do not remove the back cover; the battery is not removable and 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.

NOTES: If the battery is extremely low, you may be unable to power on the phone even when charging. Try again after charging for at least 20 minutes. Contact customer service if the phone still cannot power on after prolonged charging.

Powering On/Off & Waking Up Your Phone

Ensure the battery is charged before powering on.

To Power On: Press and hold the Power key.

To Power Off: Press and hold the Power key until the power off/restart menu appears, then touch the power off icon (represented by a circle with a vertical line). [Power Icon]

NOTES: If the screen freezes or is unresponsive, press and hold the Power key for over 10 seconds to restart the phone.

Your phone automatically enters sleep mode when not in use. The display turns off to save power, and keys are locked.

To Wake Up:

1. Press the Power key to turn the screen on.
2. Swipe up on the screen.

NOTES: If you have set up face verification, fingerprint, an unlock pattern, PIN, or password, you will need to use these to unlock your screen.

Lowering Blue Light (Eye Comfort)

Blue light (415 nm to 455 nm) can cause eye discomfort, suppress melatonin, and affect sleep. This product has a function to reduce blue radiant energy.

To avoid eye fatigue, place the product at an appropriate distance and rest your eyes by looking into the distance for 20 minutes after two hours of continuous viewing.

To enable eye protection: Open the Settings app, touch Display > Eye comfort > Turn on now. Use 'Turn on automatically' for protection between sunset and sunrise or during customized times. You can also adjust the blue light filter intensity.

Radio Frequency (RF) Energy & Exposure

General Statement on RF Energy

Your phone transmits and receives RF energy when ON. The system controls the transmission power level.

Specific Absorption Rate (SAR)

The SAR limit for mobile devices is 2 W/kg. The highest SAR values for this device, tested at the head and with 5 mm body separation, were below the limit. Detailed SAR information is available on the ZTE website: https://certification.ztedevices.com.

Body Worn Operation

To comply with RF exposure guidelines, the phone must be used with a minimum of 5 mm separation from the body. Failure to do so may exceed guideline limits.

Limiting Exposure to Radio Frequency (RF) Fields

For those concerned about RF field exposure, the World Health Organisation (WHO) advises:

Precautionary measures: Scientific information does not indicate a need for special precautions. Individuals concerned may limit RF exposure by limiting call length or using hands-free devices to keep the phone away from the head and body.

Further information is available from the WHO: http://www.who.int/peh-emf (WHO Fact sheet 193: June 2000).

Distractions

• Driving: Full attention is required for driving. Using a phone while driving can cause distraction and accidents. Comply with local laws restricting wireless device use while driving.
• Operating Machinery: Full attention is required for operating machinery to reduce accident risk.

Compliance and Disposal

CE Caution

Battery Caution:

• There is a risk of explosion if the battery is replaced by an incorrect type.
• Dispose of used batteries according to instructions.
