Keep your mobile phone with you at all times.
Before Use
Precautions for using the mobile phone
on the road

Using a phone while driving is illegal in many countries. Please follow
local laws and drive safely at all times.
near sensitive electronics
Don’t use your phone near sensitive electronic equipment – particularly
medical devices such as pacemakers – as it could cause them to
malfunction. It can also interfere with the operation of fire detectors and
other automatic-control equipment.
 For more information about how your phone affects pacemakers or
other electronic equipment, please contact the manufacturer or your
local distributor.
 Your phone may cause interference when used near TVs, radios or
automated office equipment.

while flying
Before Use

Your phone can cause interference with aircraft equipment. So it’s
essential you follow airline regulations. And if airline personnel ask you
to switch off your phone, or disable its wireless functions, please do as
they say.
in hospital

Your phone may interfere with the normal operation of medical
equipment. Follow all hospital regulations and turn it off when you’re
asked to by posted warnings or medical staff.
at a petrol station

Don’t use your phone at petrol stations. In fact, it’s always best to switch
off whenever you’re near fuels, chemicals or explosives.
around water

Keep your phone away from water (or any other liquid). It’s not a
waterproof model.
making repairs

Never take your phone apart. Please leave that to the professionals.
Before Use
Unauthorised repairs could break the terms of your warranty.
broken antenna

Don’t use your phone if the antenna is damaged, as it could cause
injury.
around children

Keep your mobile out of children’s reach. It should never be used as a
toy and it might not be good for their health.
original accessories

Only use the original accessories supplied with your phone or those
approved by the manufacturer. Using unapproved accessories may
affect performance, make the warranty void, break national regulations
on the use of mobile phones, or even cause injury.
near explosives

Turn off your phone in or near areas where explosive materials are
Before Use
used. Always obey local laws and turn off your phone when requested.
emergency calls

To make an emergency call your phone must be turned on and in an
area where there’s network coverage. Dial the national emergency
number and press ‘send’. Explain exactly where you are and don’t hang
up until help has arrived.
working temperature

The working temperature for the phone is between 0℃ and 40℃.
Please don’t use the phone outside the range. Using the phone under
too high or too low temperature might cause problems.
At very high volume, prolonged listening to a mobile phone can
damage your hearing.
Precautions for using the battery

Put the battery in a cool and ventilated place where there is no direct
sunshine.
Before Use

The battery life is usually limited, and it becomes shorter and shorter
after the battery is charged over and over again. If the charging fails
several times, this indicates that the battery is worn out and the
replacement is advised.

Dispose the worn-out batteries in designated places according to
specified regulations rather than throw them into residential garbage.

Do not throw the worn-out batteries into fire because this might cause
fire or explosion.

Do not press with great force when installing the battery because this
may result in leakage, overheating, explosion or fire.

Do not disassemble or reassemble the battery because this may result
in leakage, overheating, explosion or fire.

If the battery becomes hot, changes in color or gets deformed during
the course of use, charging or storage, please immediately stop using
and replace it.

Keep the battery away from dampness to prevent overheating,
smoldering or erosion.

Do not leave the battery in direct sunshine, around a car or
high-temperature place because this might result in leakage or
Before Use
overheating. This might affect the battery’s performance and shorten its
life.

Do not keep charging the battery continuously over 24 hours.
Note:
If the battery is damaged, please avoid contacting the materials
in it. If your skin has contacted those materials, flush your skin
with lots of water and seek for help from doctors if necessary.
Precautions for using the charger

Use the power voltage between 100VAC and 240VAC. Using the
voltage beyond the range may cause leakage, fire or damage to the
phone and charger.

Do not short-circuit the charger because this might cause electric shock,
smoldering or damage.

Do not charge the battery in direct sunshine, near dampness, dust,
vibration, TV set, or radio (may affect the image, sound), etc.

Do not use the charger if the power cable is damaged because this

might cause fire or electric shock.

Do not place water containers near the charger to avoid water splashing.
If water or any other kind of liquid splashes on the charger, immediately
remove the charger from the power socket to avoid overheating, fire,
electric shock or failure.

Do not disassemble or reassemble the charger because this might
cause body injury, electric shock, fire or damage.

Do not touch any charger, power cable or power socket with wet hands
to avoid electric shock.

Do not place heavy objects onto power cables or refit power cable
because this might cause electric shock or fire.

health and safety
SAR certification information
The device meets international guidelines for exposure to radio waves.
Your phone is a radio transmitter and receiver. It’s designed not to exceed the limits
for exposure to radio waves recommended by international guidelines. The guidelines
were developed by ICNIRP, an independent technical standards body, and include
margins designed to assure the protection of all persons, regardless of age and
health.
These guidelines use a unit of measurement known as Specific Absorption Rate,
(SAR). The SAR limit for mobile devices is 1.6 W/kg and the highest SAR value for
this device when tested was1…
Position
Head
Body
850MHz (W/Kg)
<2.0
<2.0
1900MHz (W/Kg)
<2.0
<2.0
As SAR is measured when the phone is on its highest transmitting power, the actual
SAR of this device while operating normally is typically below the levels shown above.
This is because your phone automatically changes its power level to ensure it only
uses the minimum level required to reach the network.
The World Health Organization has stated that present scientific information does not
indicate the need for any special precautions for the use of mobile devices.

Appendix
important safety information
For your own health and safety, please follow the radio frequency (RF) radiation
exposure guidelines and keep your phone no less than 1.5cm away from your body.
Failure to do this could mean that your RF exposure exceeds the guideline limits.
how to limit your radio frequency (RF) exposure
The World Health Organization (WHO) gives the following advice to people who want
to limit their exposure to RF radiation…
Present scientific information does not indicate the need for any special precautions
for the use of mobile phones. If individuals are concerned, they may choose to limit
their own or their children’s RF exposure by limiting the length of calls, or using
‘hands-free’ devices to keep mobile phones away from the head and body.
Further information on the subject can be obtained from the World Health
Organization website at http://www.who.int/peh-emf WHO Fact sheet 193: June 2000.


This mobile phone 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.
 This mobile phone 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 radiated 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

conjunction with any other antenna or transmitter.
RF Exposure Information (SAR)

This mobile phone meets the government’s requirements for exposure
to radio waves.

This phone 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 phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR. The
SAR limit set by the FCC is 1.6W/kg. Tests for SAR are conducted
using standard operating positions accepted by the FCC with the phone
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 phone while operating can be well
below the maximum value. This is because the phone is designed to
operate at multiple power levels so as to use only the poser required to
37
Appendix
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 model phone as reported to the FCC
when tested for use at the ear is 0.617 W/kg and when worn on the
body, as described in this user guide, is 0.395 W/kg (Body-worn
measurements differ among phone models, depending upon available
accessories and FCC requirements.)


While there may be differences between the SAR levels of various
phones and at various positions, they all meet the government
requirement.


The FCC has granted an Equipment Authorization for this model phone
with all reported SAR levels evaluated as in compliance with the FCC
RF exposure guidelines. SAR information on this model phone is on file
with the FCC and can be found under the Display Grant section of
www.fcc.gov/oet/ea/fccid after searching on FCC ID: Q78-UX720.


For body worn operation, this phone has been tested and meets the
FCC RF exposure guidelines for use with an accessory that contains no
metal and the positions the handset a minimum of 1.5 cm from the body.
Use of other accessories may not ensure compliance with FCC RF
exposure guidelines. If you do not use a body-worn accessory and are
not holding the phone at the ear, position the handset a minimum of 1.5
cm from your body when the phone is switched on.
