Power off your phone before removing or replacing the battery. 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. Place your finger into the slot at the lower left of the back cover, and gently lift and remove the cover. 2. Install the nano-SIM card and the optional microSDXC card into the respective card slots. 4 3. Insert the battery, making sure the connectors align. Gently push down on the battery until it clicks into place. 4. Replace the back cover. 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 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 in the correct direction. 5 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: If the screen freezes or takes too long to respond, reinstall the battery and power on again. 6 FM Radio Scanning for Channels 1. Plug in a wired headset, open the app list and touch FM Radio. 2. Touch > Scan. Your phone scans for all available channels and saves them to the channel list. Listening to FM Radio 1. Open FM Radio while the headset is connected. 2. Touch > All channels and select a channel. You can also drag the red line along the frequency panel or touch or to switch to other channels, or touch or to adjust the current channel frequency. NOTES: • Touch to add the channel to favorites. • Touch to listen to the radio through the phone speaker. • The FM radio feature does not require an Internet connection. 7 Product Safety Information Don’t make or receive phone calls while driving. Never text while driving. Keep your phone at least 15 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 nea r 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 dry. Do not attempt to disassemble your phone. 8 Only use approved accessories. Don’t rely on your phone as a primary device for emergency communications. FCC RF Exposure Information (SAR) This phone is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the United States. During SAR testing, this device was set to transmit at its highest certified power level in all tested frequency bands, and placed in positions that simulate RF exposure in usage against the head with no separation, and near the body with the separation of 15 mm. Although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach …

Pre-Scan has been conducted to determine the worst-case mode from all possible combinations between available modulations, bandwidth, resource block (RB) and RB offset. Following channels were selected for test: Channel Bandwidth Low Channel Mid Channel High Channel Frequency (MHz) Channel No. Frequency (MHz) Channel No. Frequency (MHz) Channel No. 1.4MHz 814.7 26697 819.0 26740 823.3 26783 3MHz 815.5 26705 819.0 26740 822.5 26775 5MHz 816.5 26715 819.0 26740 821.5 26765 10MHz --- 819.0 26740 --- Following modes were selected as the worst case configuration for each test: Test Items Channel BW (MHz) RB Size RB Offset Modulation Antenna Orientation RF Output Power L\M\H 1.4 1\3\6 0\3\5\1 QPSK,16QAM, 64QAM N/A 3 1\8\15 0\8\14\4\7 5 1\12\25 0\12\24\7\13 10 1\25\50 0\25\49\12 Peak to Average Power …

Limit FCC 47 CFR Part 90 Subpart S - §90.209 (a) Each authorization issued to a station licensed under this part will show an emission designator representing the class of emission authorized. The designator will be prefixed by a specified necessary bandwidth. This number does not necessarily indicate the bandwidth occupied by the emission at any instant. In those cases where §2.202 of this chapter does not provide a formula for the computation of necessary bandwidth, the occupied bandwidth, as defined in part 2 of this chapter, may be used in lieu of the necessary bandwidth. 3.3.2. Test Setup 3.3.3. Test Procedures 1) The measurement procedure follows ANSI C63.26-2015, clause 5.2.7 2) The RF output of the EUT, BS simulator and spectrum analyzer are connected via a power divider. 3) The nominal RBW of spectrum analyzer shall be in the range of 1% to 5% of the anticipated OBW, and the VBW shall be set ≥ 3 × RBW. 4) Record the measured results of 26dB and 99% bandwidth. 3.3.4. Test Result Test Engineer Xu Dongxu Test Date 2021/01/27 Temperature 20.2°C Relative Humidity 46.9% Pressure 105.1kPa Test Sample Selected No.1 Frequency (MHz) Channel No. BW (MHz) RB Size RB Offset Bandwidth of 99…
