1. Safety Precautions
Information for parents
Please read the operating instructions and safety precautions carefully
before use.
Explain the content to your children and the hazards associated with
using the phone.
Remember to comply with legal requirements and local
restrictions when using the phone, for example, in
airplane, petrol stations, hospitals or while driving.
Mobile phones can interfere with the functioning of
medical devices such as hearing aids or pacemakers.
Keep at least 20 cm (9 inches) between the phone and
pacemaker. When using the mobile phone hold it to the ear which is
furthest away from the pacemaker. For more information, consult
your doctor.
Always keep the phone and accessories out of reach of
small children.
Small parts such as the SIM card, dust cap, lens ring and
lens cap as well as the microSD card can be dismantled and
swallowed by small children.

5
Do not place the phone near to electromagnetic data
carriers such as credit cards and floppy disks. Information
stored on them could be lost.
Do not look directly into the LED (such as flash LED)
with optical magnifiers because of radiation.
This product complies with IEC/EN 60825-1 “Safety of
Laser Products” for LED Class 1M products; such products are safe
under reasonably foreseeable operating conditions.
Permanent hearing loss may occur if you use earphones
or headphones at high volume. You can adapt over time to
a higher volume, which may sound normal but can be
damaging to your hearing. Set your volume to a safe level.
If you experience discomfort or buzzing in your ears, reduce the
volume or discontinue use of your earphones or headphones.
Ring tones, info tones and handsfree talking are
reproduced through the loudspeaker. Do not hold the
phone to the ear when it rings or when you have switched
on the handsfree function. Otherwise you risk serious
permanent damage to your hearing.
The mains voltage (V) specified on the power supply unit
must not be exceeded. Otherwise the charging device may

6
be damaged.
The power supply must be plugged into an easily accessible AC
mains power socket when charging the battery. The only way to turn
off the charging device after charging the battery is to unplug it.
You may only open the phone to replace the battery, SIM
and microSD card. You must not open the battery under
any circumstances. All other changes to this device are
strictly prohibited and will invalidate the guarantee.
The phone may cause interference in the vicinity of TV
sets, radios and PCs.
Dispose of unwanted batteries and phones as permitted by
the laws in your countries.
Only use original batteries and charging devices.
Otherwise you risk serious damage to health and property.
The battery could explode, for instance.
All batteries can cause property damage, injury or burns if a
conductive material such as jewelry, keys or beaded chains touch
exposed terminals. The material may complete an electrical circuit
and become quite hot. Exercise care in handling any charged battery,
particularly when placing it inside your pocket, purse or other

7
container with metal objects.
Do not dispose of batteries in fire as they may explode.
Improper use will invalidate the guarantee! These safety instructions
also apply to original accessories.
As mobile devices offer a range of functions, they can be used in
positions other than the head, such as directly on the body. In this
case, the limits are met too.
