To the Owner

•

Some electronic devices are susceptible to electromagnetic

interference sent by your device if inadequately shielded,

such as the electronic system of vehicles. Please consult the

manufacturer of your device before using if necessary.

•

Operating your device may interfere with medical devices

such as hearing aids and pacemakers. Please always keep

•

Be aware of the usage limitation when using your device

at places such as oil warehouses or chemical factories,

where there are explosive gases or explosive products being

processed. Power off your device if required.

•

The use of electronic transmitting devices is forbidden in

aircrafts, at petrol stations and in hospitals. Please observe

and obey all warning signs and power off your device in these

conditions.

•

Do not touch the inner antenna area if not necessary.

Otherwise it will affect your device’s performance.

•

Store your device out of the reach of little children. Your device

Using Your Device

•

Please use original accessories or accessories that are

authorized. Using any unauthorized accessories may affect

your device’s performance, and violate related national

regulations about telecom terminals.

•

Avoid using your device near or inside metallic structures

or establishments that can emit electromagnetic waves.

Otherwise it may inﬂuence signal reception.

•

Your device is not waterproof. Please keep it dry and store in a

shady and cool place.

•

Do not use your device immediately after a sudden

temperature change. In such case, it will produce dew inside

and outside your device, so don’t use it until it becomes dry.

•

Handle your device carefully. Do not drop, bend or strike it.

Otherwise your device will be damaged.

•

No dismantling by non-professionals and only qualiﬁed

technicians can undertake repair work.

•

Operating temperature range of 0°C ~ +35°C and humidity

range of 5% ~ 95% are recommended.

Using Battery

•

Do not short-circuit the battery, as this can cause excessive

heat and ﬁre.

•

Do not store battery in hot areas or dispose of it in a ﬁre to

avoid explosion.

•

Do not disassemble or modify the battery.

your skin, wash your skin with abundant fresh water and ask

doctor for help if necessary.

Radio Frequency (RF) Energy

This device meets the government’s requirements for exposure

to radio waves.

This device is designed and manufactured not to exceed the

emission limits for exposure to radio frequency (RF) energy

set by the Federal Communications Commission of the U.S.

Government:

The exposure standard for wireless mobile devices employs a

unit of measurement known as the Speciﬁc Absorption Rate,

or SAR. The SAR limit set by the FCC is 1.6 W/kg. *Tests for SAR

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. This is because the device is designed to

operate at multiple power levels so as to use only the poser

53

Regulatory and Safety Information

52

required to reach the network. In general, the closer you are to a

wireless base station antenna, the lower the power output.

The highest SAR value for the device as reported to the FCC

when tested for use at the ear is 1.08 W/kg and when worn on the

body, as described in this user guide, is 1.08 W/kg (Body-worn

measurements differ among device models, depending upon

available enhancements and FCC requirements.)

While there may be differences between the SAR levels of

various devices and at various positions, they all meet the

government requirement.

The FCC has granted an Equipment Authorization for this device

with all reported SAR levels evaluated as in compliance with the

FCC RF exposure guidelines. SAR information on this device is

on ﬁle with the FCC and can be found under the Display Grant

section of

http://www.fcc.gov/oet/ea/fccid/

after searching on:

FCC ID: SRQ-MF923

SAR compliance for body operation is based on a separation

distance of 10 mm between the unit and the human body. Carry

this device, at least 10 mm away from your body to ensure RF

exposure level compliant or lower to the reported level.

FCC Compliance

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.

Caution:

Changes or modiﬁcations not expressly approved by

the manufacturer 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 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.

c) Only use the battery for the system for which it is speciﬁed.

d) Only use the battery with a charging system that has

been qualiﬁed with the system per CTIA Certiﬁcation

Requirements for Battery System Compliance to IEEE 1725.

Use of an unqualiﬁed battery or charger may present a risk of

ﬁre, explosion, leakage, or other hazard.

e) Do not short circuit a battery or allow metallic conductive

objects to contact battery terminals.

f) Replace the battery only with another battery that has been

qualiﬁed with the system per this standard, IEEE-Std-1725.
