1. Safety Precautions
electronic devices including medical
Reading the guidelines below will minimize the risk
of misusing the phone.
• USING – The telephone emits electromagnetic
field that might negatively interfere with other
equipment.
• Never use the phone wherever such use is
prohibited, in hospitals, airplanes, refuelling
points or at proximity to flammable materials.
Using the phone in such places might expose
others to danger.
• Never use the phone without a headset while
driving.
• A device and its accessories might contain
small parts. Keep the phone and all parts out
of reach of children.
• SERVICE - Never repair nor modify the phone
on your own; all repairs should be made by
authorized service only.
• CLEANING - Never cl ean the phone with any
chemicals or corrosives.
• TORCH – Never look directly into the beam of
light.
• HEARIN G AID – If you have a hearing aid, the
phone volume should be carefully adjusted in
line with the hearing aid sensitivity.
• ELECTRONIC MEDICAL EQUIPMENT – Yo u r
phone is a radio transmitter, that might interfere
with the performance of electronic medical
equipment or implants, heart pace makers,
insulin pumps, etc. Keeping a distance no
shorter than 15 cm between the phone and the
implant is recommended. To learn more about
it, contact your health care provider or
manufacturers of such medical equipment.

20. Battery information
There is a battery in the phone. The battery can be
recharged using a charger that is included in the
set.
The battery life depends on conditions in which the
phone is used. Your distance from a relay
transmitter, number and the length of phone calls
significantly Reduce the battery life. While on the
go, the phone switches between relay transmitters
and such switching also significantly affects the
battery life.
After multiple charges and discharges, it is natural
for the battery to eventually lose its ability to hold
charge. Get a new battery if you notice a significant
drop in the battery performance.
Use only batteries recommended by the
Manufacturer.
22
Never leave the charger connected l onger than 2-3
days.
Never keep the phone in excessively hot places.
battery installation for proper polarization.
Leaving the battery in excessively hot or cold places
will Reduce the battery life. The recommended
storage temperature range is between 15°C and
25°C. Installing a cold battery into the phone might
cause the phone to malfunction and might damage
the phone.
CAUTION : RISK OF EXPLOSION IF BATTERY IS
REPLACED BY AN INCORRECT TYPE. DISPOSE
OF USED BATTERIES ACCORDING TO THE
INSTRUCTIONS.
21. SAR information
Information about the impact of radio waves and
Specific Absorption Rate [SAR]. This phone model
has been designed to meet all international
standards pertaining to the impact of radio waves as
recommended by international guidelines. These
guidelines were developed by the International
Commission on Non-Ionizing Radiation Protection
(ICNIRP), an independent scientific organization with
a safety margin to protect all people regardless their
age and health condition. Such guidelines use a unit
of measurement called Specific Absorption Rate
(SAR) – actual absorption.
High temperatures might
negatively impact both the
battery and the phone.
Never use a battery that is
clearly damaged. Doing so might
cause a short circuit, and might
damage the phone. Check
23
As recommended by ICNIRP, the border value of
Highest value of SAR
SAR for portable equipment is 2,0 watts per kilogram
(W/kg), and it is an average value per 10g of tissue.
SAR value is determined at the maximum transmit
power and in the full spectrum of frequencies
covered by research; the actual SAR value while the
product is working might be much lower than the
maximum level. Such discrepancies result from
automatic changes in device power necessary to
ensure that the device operates at a minimum power
level required to be connected with network.
This device was tested for typical body-worn
operations. To comply with RF exposure
requirements, a minimum separation distance of
5mm must be maintained between the user’s body
and the handset, including the antenna. Third-party
belt-clips, holsters, and similar accessories used by
this device should not contain any metallic
components. Bod y-worn accessories that do not
meet these requirements may not comply with RF
exposure requirements and should be avoided. Use
only the supplied or an approved antenna.
In case of this model, the highest SAR value in tests
is:
GSM 900 1,42 1,514
