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. If your
device gets wet, remove the battery and refrain from turning on device.
Wipe it with a dry cloth and take it to the service center.
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.
Licking the battery or charger is strictly prohibited; saliva is more corrosive
than water. Residual saliva may short-circuit phone and damage its

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 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.

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: F4(FCC
ID: 2ADYY-F4) has also been tested against this SAR limit. The highest
SAR value reported under this standard during product certification
for use at the ear is1.29 W/kg and when properly worn on the body is
0.51W/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 1.0cm
must be maintained between the user’s body and the handset,
including the antenna. Third-party belt-clips, holsters, and similar
22
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.
