Using the Lithium Battery
Charge before using
To reduce electrical emission in the battery, remove the battery from the device if not in use for a long time. Keep the battery in cool and dry places.
Store the battery for a long time:
Remove battery from device;
- Charge and discharge the battery to 40%-65% status if it will NOT be used for 10 days or more. This can greatly extend battery life.
- The battery automatically discharges to below 65% when idle for more than 10 days to prevent swelling.
- Store the battery in cool and dry places (with the temperature lower than 25°C).
Feature of the Lithium Battery
- After repeated charging processes, the capacity will decrease.
- The battery capacity decays gradually even without being used.
- More charging time is required when a Lithium battery is charged in cool conditions.
- Charging and storage of Lithium battery in relatively warm conditions will jeopardize its service life. Do not keep them inside a vehicle or near ignition sources or fire.
- If the battery working time reduces significantly, replace the battery immediately to prevent fluid leak.
Charging Lithium battery
Connect the device with an AC adapter. When powered on, the indicator light turns red. The indicator light turns green when charging is finished. The indicator light turns off when exposed to high operating temperature, poor contact, or battery damage.
Connect the device and Power adapter by Micro USB cable. The LED indicator light is on during charging.

Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- This device must accept any interference received, including interference that may cause undesired operation.
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 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.
SAR tests are conducted using standard operating positions accepted by the FCC with the device transmitting at its highest certified power level in all tested frequency bands. 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. Before a new model device is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the exposure limit established by the FCC. Tests for each device are performed in positions and locations (worn on the body) as required by the FCC. For body worn operation, this model phone has been tested and meets the FCC RF exposure guidelines when used with an accessory designated for this product or when used with an accessory that contains no metal and that positions the handset a minimum of 5 mm from the body. Non-compliance with the above restrictions may result in violation of RF exposure guidelines.
