●●When you are in an airplane.
●●●When you are in the vicinity of flammable atmospheres and is indicated by the entity
responsible for risk management.
●●●When you are in the vicinity of electro-explosive devices and is indicated by the entity
responsible for risk management.
Respect special regulations in force in any area, and always switch off your phone
when its use is prohibited, or if it could cause danger. When connecting the phone or
any accessory to another device, read user manual for detailed safety instructions. Do
not connect incompatible products. It is recommended that the equipment should only
be used in normal position for proper operation and personnel safety. Do not expose to
temperatures below -10 °C or above 50 °C.
Medical equipment
Be sure to turn off the phone near electronic medical equipment which obviously require
that the phone is turned off (such as pacemakers, hearing aids, etc.).
Most medical devices can be protected from RF signal of the phone, but not all of them.
If you have any questions or need more information, consult your doctor or manufacturer
of your medical device.
Auditive Protection
This phone complies with current regulations to limit the maximum output
volume. Using headphones at very high volume may cause hearing damage.

7
Precautions for use
●Turn down the volume or stop using the product if your ears are ringing.
●●Do not raise the volume too much, doctors warn against the prolonged exposition to
high volume.
●●Excessive acoustic pressure from headphones can cause hearing loss.
●●To prevent possible hearing damage, do not listen for long period at high volume.
Pacemakers
Pacemaker manufacturers warn that distance between phone and heart pacemaker
must be at least 6 inches (15.3 cm).
People with pacemakers should consider the following:
●Always keep a distance (at least 6 inches) between phone and pacemaker when
phone is on.
●●●Do not carry your phone near your chest.
●●●Use the phone with the opposite ear from the pacemaker.
Please turn off your phone if you feel there is interference, consult your doctor as soon
as possible.
Emergency calls
Like any mobile phone, this device works with radio signals that can not guarantee
connection in all conditions. Therefore, you should never rely solely on a mobile phone
for essential communications like medical emergencies. To make or receive calls, phone
must be switched on and in a service area with adequate signal strength. To make an
emergency call, enter local emergency number in standby mode and press call button.

8
Precautions for use
Care and maintenance
●Listening to a music player at a very high volume can damage the user’s hearing
and cause hearing problems (temporary or permanent deafness, ringing in the ears,
tinnitus, hyperacusis). Therefore, it is strongly recommended that you do not use the
player at full volume or for more than one hour a day at medium volume.
●Keep the phone away from children and pets. They could damage the phone
accidentally or choke on small parts. Do not drop or knock the phone. Rough handling
can damage electronic circuits.
●Keep the phone dry and avoid liquids that could corrode the phone. Do not use the
phone with wet hands, which may cause electric shock.
●Do not place the phone in areas of excessive heat, which may shorten the life of
electronic devices, damage batteries, or melt accessories.
●Do not place the phone in cold areas. When the phone warms up to its normal
operating temperature, moisture can accumulate inside the phone, which may
damage electronic circuits.
●Do not place the phone in areas exposed to sunlight as it may cause overheating.
●Do not place the phone near flammable liquids, gases or explosive substances.
●To clean the telephone, use a damp or antistatic cloth. Do not use a dry or static cloth.
Do not use chemicals such as cleaning solvents to clean the surface of the phone.
Turn off your phone before cleaning.
●Do not apply paint over the phone, as it can prevent proper operation.
●The manufacturer’s warranty does not cover repair the appliance if the phone or
battery gets wet, or phone label is damaged even when the phone warranty has not
expired.
●Always make sure your device is turned off before removing your SIM card. This
will prevent data loss and damage to the SIM card. Do not place the SIM card near
surfaces or electromagnetic environments and avoid touching the metal connectors.

Precautions for use
Measures that affect the safety of users
●Do not use the mobile phone in certain situations (while driving) and certain places
(airplanes, hospitals, schools, gas stations and professional workshops).
●For mobile phones, remember the prohibition of using the phone manually by the
driver of a moving vehicle.
●Users of electronic implants (pacemakers, insulin pumps, neurostimulators, etc.)
must take the following precautions: the distance between the mobile phone and the
implant must be at least 15 cm; the position of the phone, during the call, must be on
the opposite side of the implant.
Instructions for use to reduce the level of consumer exposure to
radiation (this advice is given as a simple precautionary measure, no danger associated
with the use of a mobile phone has been observed)
●The use of a mobile phone in good reception conditions is recommended to reduce
the amount of radiation received (especially in an underground car park, when
traveling by train or car ...).
●Make reasonable use of radio equipment, such as mobile phones, by children and
adolescents, for example, avoiding night-time communications and limiting the
frequency and duration of calls.
●Indication of good reception parameters (for example: display on the telephone screen
of four or five bars).

precautions during a call: keep the phone away from the stomach in pregnant women
or the lower abdomen in adolescents.

Precautions for use
Battery use
●Never use any charger or battery if damaged. Use the battery correctly. Do not short-
circuit the battery, as this may damage the battery or cause a fire.
●Do not subject the battery to high temperatures or fire as it may explode.
●Return the old battery to the dealer, or place it in locations designated for recycling. Do
not throw the battery in household waste.
●The charging time depends on the remaining battery charge, the type of battery and
charger used. Use only original chargers, batteries and accessories approved by the
manufacturer.
●The battery can be charged and discharged hundreds of times, but its duration will
gradually decrease. When the operation time is noticeably shorter than normal,
replace the battery with a new one.
●Disconnect the charger from the electrical plug and the device when the phone is not
in use. Do not overload your battery as it may damage or shorten its life.
●Do not expose the battery to places of extremely hot or cold temperatures, as it
will reduce the battery capacity. The Li-ion batteries are particularly affected by
temperatures below 0° C.
When the battery level is low, the phone will issue a warning tone and a low battery
message. Connect the power adapter into the device to start charging. Battery level is
indicated on the screen during the charging process, and once it is fully charged, the
battery icon will appear full. Charging a completely discharged battery can comprise 2 to
3 hours. Fully charge the battery before using the device for the first time.
