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.
4
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.
5
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.

Labelling requirements.
This device complies with part 15 of the FCC Rules.
Operation is subject to the condition that this device does
not cause harmful interference.
Information to user.
Any Changes or modifications not expressly approved by
the party responsible for compliance could void the user's
authority to operate the equipment.
Information to the user.
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
17
and on, the user is encouraged to try to correct the
interference by one or more of the following 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.
Specific Absorption Rate (SAR) information:
This Mobile phone meets the government's requirements
for exposure to radio waves. The guidelines are based on
standards that were developed by independent scientific
organizations through periodic and thorough evaluation
of scientific studies. The standards include a substantial
safety margin designed to assure the safety of all persons
regardless of age or health.
FCC RF Exposure Information and Statement
The SAR limit of USA (FCC) is 1.6 W/kg averaged over one
gram of tissue. Device types: WX4 Pro (FCC ID:
2ADYY-WX4PRO) has also been tested against this SAR
limit. The highest SAR value reported under this standard
during product certification for use at the ear is
0.860W/kg and when properly worn on the body is
18
1.100W/kg. This device was tested for typical body-worn
operations with the back of the handset kept 10mm from
the body. To maintain compliance with FCC RF exposure
requirements, use accessories that maintain a 10mm
separation distance between the user's body and the back
of the handset. 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.
Body-worn Operation
This device was tested for typical body-worn operations.
To comply with RF exposure requirements, a minimum
separation distance of 1.0 cm must be maintained
between the user’s body and the handset, including the
antenna. Third-party belt-clips, holsters, and similar
accessories used by this device should not contain any
metallic components. Body-worn accessories that do not
meet these requirements may not comply with RF
exposure requirements and should be avoided. Use only
the supplied or an approved antenna.
