Your device is a product of superior design & craftsmanship
and should be handled with care: The following
recommendations will help protect your phone:
Keep the device dry. Precipitation, humidity, and all
types of liquid or moisture may contain minerals that
can rust electronic circuits. Shut down the phone
when it suffered water damage (Do not pull out the
battery), and boot up the phone after it is dry.
Do not store the device under extreme temperatures;
it can damage the battery and shorten device lifespan.
Do not use or store device in dusty and dirty areas; the
electronic components may be damaged.
Do not attempt to open device in any way other than
instructed in this guide. Repairs attempted by an
entity other than designated service agent/center will
void warranty.
2
Licking the charger is strictly prohibited; saliva is more
corrosive than water. Residual saliva may short-circuit
phone and damage its motherboard, causing the device to
become inoperable; charger may also be damaged in the
process.
WARNING:
Licking USB plug is strictly prohibited.
Do not drop, knock, or shake device. Rough handling
can disrupt internal circuit boards and fine mechanical
parts.
Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the device. Use a soft and
dry cloth to wipe down surfaces.
3
Do not place battery in fire, explosion may occur. With
concern for the environment, please abide local laws
& ordinances in battery disposal.
Only use original battery, charger, and accessories
applicable to the specific mobile model. Failure to do
so voids the warranty and may result in a hazard.
Power off mobile prior to testing its charger. If charger
malfunctions, off-mode will prevent damage to the
motherboard.
Please keep the charging mobile away from small
children.
Do not touch charger or mobile with wet hands; it’s
hazardous and may damage electronic parts.
WARNING:
Risk of explosion if original battery is replaced.
Tampering with mobile OS and ROOT voids warranty
and may cause software instability.

“Factory data reset” resets all configurations to their
default state. Internal mobile storage is cleared of all data
including apps, photos, music, videos, mail, contacts, etc.
This procedure may take a long time. Please wait patiently
for mobile to restart and do not power off.
WARNING:
Factory data reset as a last resort. Once activated all user
data & configurations are deleted and cannot be restored.

Specific Absorption Rate (SAR) Certification
THIS DEVICE MEETS INTERNATIONAL GUIDELINES FOR
EXPOSURE TO RADIO WAVES
Your mobile device is a radio transmitter and receiver. It is
designed not to exceed the limits for exposure to radio
waves (radio frequency electromagnetic fields)
recommended by international guidelines. The guidelines
were developed by an independent scientific organization
(ICNIRP) and include a substantial safety margin designed
to assure the safety of all persons, regardless of age and
health.
The radio wave exposure guidelines use a unit of
measurement known as the Specific Absorption Rate, or
SAR. The SAR limit for mobile devices is 1.6 W/kg. Tests
for SAR are conducted using standard operating positions
with the device transmitting at its highest certified power
level in all tested frequency bands. The highest SAR values
under the ICNIRP guidelines for this device model are:
Maximum SAR for this model and conditions under which
it was recorded
Head
0.724W/Kg
Body
0.799 W/Kg
During use, the actual SAR values for this device are
usually well below the values stated above. This is
15
because, for purposes of system efficiency and to
minimize interference on the network, the operating
power of your mobile device is automatically decreased
when full power is not needed for the call. The lower the
power output of the device, the lower its SAR value.
A body-worn SAR test has been performed on this device
at a separation distance of 5mm. To meet RF exposure
guidelines during body-worn operation, the device must
be positioned at least 10mm away from the body.
Organizations such as the World Health Organization and
the US Food and Drug Administration have suggested that
if people are concerned and want to reduce their
exposure, they could use a hands-free accessory to keep
the wireless device away from the head and body during
use, or reduce the amount of time spent using the device.
For more information, visit www.tecno-mobile.com and
search for your device with the model number.

This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1)
this device may not cause harmful interference, and (2)
this device must accept any interference received,
including interference that may cause undesired
operation. changes or modifications not expressly
approved by the party responsible for compliance could
void the user's authority to operate the equipment.
NOTE: This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference in a residential installation. This
equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However, there is
no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to
radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the
following
17
measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and
receiver.
-- Connect the equipment into an outlet on a circuit
different
from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV
technician for help.
NOTE: This device and its antenna(s) must not be
co-located or operation in conjunction with any other
antenna or transmitter.
RF Exposure Statement
To maintain compliance with FCC’s RF Exposure guidelines,
This equipment should be installed and operated with
minimum distance of 10mm the radiator your body.
This device and its antenna(s) must not be co-located or
operation in conjunction with any other antenna or
transmitter. Changes or modifications to this unit not
expressly approved by the party responsible for
compliance could void the user’s authority to operate the
equipment.
For 5G WiFi：
(1)the device for operation in the band 5150-5250 MHz is
only for indoor use to reduce the potential for harmful
interference to co-channel mobile satellite systems;
18
(2)the maximum antenna gain permitted for devices in
the bands 5250-5350 MHz and 5470-5725 MHz shall
comply with the e.i.r.p. limit; and the maximum antenna
gain permitted for devices in the band 5725-5825 MHz
shall comply with the e.i.r.p. limits specified for
point-to-point and non point-to-point operation as
appropriate.
(4) Users should also be advised that high-power radars
are allocated as primary users (i.e. priority users) of the
bands 5250-5350 MHz and 5650-5850 MHz and that
these radars could cause interference and/or damage to
LE-LAN devices.
RF Exposure Information:
The SAR limit of USA (FCC) is 1.6W/kg averaged over one
gram of tissue. Device Types (FCC ID: 2ADYY-CXAIR) has
also been tested against this SAR limit.
The highest SAR value reported under this standard
during product certification for use when properly worn
on the body is 0.799 W/kg and for head is 0.724W/kg.
Simultaneous RF exposure is 1.012W/Kg.
This device was tested for typical body‐worn operations
with the back of thehandset kept 10mm from the body.To
maintain compliance with FCC RF exposure requirements,
use accessories that antain a 5mm separation distance
between the user's body and the back of thehandset.
19
The use of belt clips, holsters and similar accessories
should not containmetallic components in its assembly.
The use of accessories that do not satisfy
theserequirements may not comply with FCC RF exposure
requirements, and should beavoided.
The use of belt clips, holsters and similar accessories
should not contain metallic components in its assembly.
The use of accessories that do not satisfy these
requirements may not comply with FCC RF exposure
requirements, and should be avoided.
