1.2 Precaution before using battery
Do not leave battery unused for long time, no matter it is in
device or inventory. If battery has been used for 6 months
already, it should be check for charging function or it should be
disposed correctly.
The lifespan of Li-ion battery is around 2 to 3 years, it can be
circularly charged for 300 to 500 times. (One full battery charge
period means completely charged and completely discharged.)
When Li-ion battery is not in used, it will continue discharge
slowly. Therefore, battery charging status should be checked
frequently and take reference of the related battery charging
information on the manuals.
Observe and record the information of a new unused and non-
fully charged battery. On the basis of operating time of new
battery and compare with a battery that has been used for long
time. According to product configuration and application
program, the operating time of battery would be different.
Check battery charging status at regular intervals.
When battery operating time drops below about 80%, charging
time will be increased remarkably.
If a battery is stored or otherwise unused for an extended
period, be sure to follow the storage instructions in this
document. If you do not follow the instructions, and the battery
has no charge remaining when you check it, consider it to be
damaged. Do not attempt to recharge it or to use it. Replace it
with a new battery.
Store the battery at temperatures between 5 °C and 20 °C
(41 °F and 68 °F).

FCC statements:
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.
NOTE: The manufacturer is not responsible for any radio or TV interference
caused by unauthorized modifications or changes to this equipment. Such
modifications or changes 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 prote ction 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, ma y cause harmful interference to radio
communications. However, there is no guarant ee that interference will not
occur in a particular installation. If thi s equipment does cause harmful
interference to radio or television rec eption, 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 equipm ent and receiver.
‐Connect the equipment into an outlet on a ci rcui t di fferent from that to
which the receiver is connected.
‐Consult the dealer or an experienced radio/TV technician for help.
During SAR testing, this device is set to transmit at its highest certified
power
level in all tested frequency bands, and placed in positions that simulate RF
exposure in usage near the body with the separa t i on of 10 mm. Although the
29
SAR is determined at the highest certified power level, the actual SAR level
of
the while operating can be well below the ma ximum value. This is because
the device is designed to operate at multiple power levels so as to use only
the power required to reach the network. In general, the closer you are to a
wireless base station antenna, the lower the power output.
FCC Radiation Exposure Statement
. 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 requi rements, use
accessories that maintain a 10 mm 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.
RF Exposure Information(SAR)
The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue.
Device
Types C75 (FCC ID: 2AC6AC75) 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 is0.655 W/kg and for
head is 0.479 W/kg.
