Tips for Reducing Exposure Levels
We recommend that you use your phone in good reception
conditions in order to reduce the amount of radiation received.
It is advisable to limit the amount of time you use the phone in
underground car parks and when travelling by car or train, etc.
Reception conditions are indicated by the bars that are
displayed on your phone: the more bars there are, the
better the reception quality.
We recommend that you use the hands-free kit to reduce
exposure to radiation.
To reduce the adverse effects of prolonged radiation
exposure, we advise teenagers to hold the phone away
from their lower abdomen, and that pregnant women hold
the phone at a distance from their stomach.

Only qualified service personnel should repair your
device. If you give your device to non-qualified personnel
for repair, the phone will not be covered by WIKO's warranty.
14.
The IMEI code is the serial number used to identify your
device and for After-Sales support. There are several ways
of finding your IMEI code:
• Type * # 06 # on your mobile telephone's keypad.
• Refer to the packaging box that your telephone came in.
• Remove the battery from your device: on the back, you will
see a label with your IMEI code. (For non-removable batteries,
refer to the IMEI engraved on the telephone's rear casing).
