User's Manual

standby time are greatly affected by the signal strength on the cellular network and the

parameters set by the network operator.

z Battery charging time depends on the remaining battery charge, the type of battery,

and the charger used. The battery can be charged and discharged hundreds of times, but it

will gradually wear out. When the operation time is noticeably shorter than normal, it is time

to buy a new battery.

z If left unused, a fully charged battery will discharge itself over time.

z Extreme temperatures will affect the charging capacity of your battery: it may require

cooling or warming first.

z Do not leave the battery in hot or cold places because the capacity and lifetime of the

battery will be reduced. Try to keep the battery at room temperature. A phone with a hot or

cold battery may not work temporarily, even when the battery is fully charged. Li-ion

batteries are particularly affected by temperatures below 0°C (32°F).

z Use only approved batteries and chargers. Disconnect the charger from the power

source when it is not in use. Do not leave the battery connected to a charger for more than a

week, since overcharging may shorten its lift.

RF Exposure Information

The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device

(FCC ID: SG70906HC-C2070) 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

0.683 W/kg and when properly worn on the body is 0.921 W/kg. This device was tested

for typical body-worn operations with the back of the handset kept 1.5cm from the body.

To maintain compliance with FCC RF exposure requirements, use accessories that

maintain a 1.5cm 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.

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 to this equipment. Such modifications could void the user’s

authority to operate the equipment.
