Batteries - SIM - Emergency calls - SAR - Repairs
1.
To increase the life of your battery, only use WIKO
chargers and batteries. Replacing the battery with a non-
compliant model may result in the latter exploding.
2. Never throw batteries on a fire and follow the guidelines
in force for recycling used batteries and phones.
3.
Be careful not to crush or damage the battery, as this
could cause an internal short circuit and overheating.
4. Do not take the battery apart.
5. The battery can be recharged several hundred times
before needing to be replaced. When it shows signs of
losing its power, it can be replaced.
6.
If you do not use your mobile phone for an extended period,
remember to recharge the battery to optimise its use time.
7.
Do not throw batteries away with household waste:
recycle them in accordance with the manufacturer's
guidelines. If the battery is damaged, contact the after-sales
service or the nearest authorised WIKO dealer.
8. Unplug the charger from the wall socket when the battery
is fully charged in order to reduce your energy consumption.
9.
Do not leave the battery being charged for more than a
week as this might result in an overload and reduce the
life of the product.
10.
Handle the SIM cards with care: wipe them with a soft
cloth if they appear dirty.
11.
Emergency calls: the emergency numbers may not be
accessible on all mobile telephone networks, in isolated
areas or areas where there is no coverage; check first with
your operator.
12. Radio Frequency Exposure:
Your device has been designed and produced to comply
with international norms (ICNIRP) for exposure to
radiofrequencies. The safety instructions related to
exposure to radio frequencies use a measuring unit called
SAR (Specific Absorption Rate).
The local specific absorption rate (SAR) measures the
user's exposure to the electromagnetic waves of the
equipment concerned. The maximum authorised SAR is
2 W/kg for the head and torso, and 4 W/kg for the limbs.
The highest reported SAR value for your device when
tested for use and kept 0.5 cm from your body is :
SAR Head : 0.562 W/kg
SAR Torso : 1.608 W/kg
SAR Limbs : 3.028 W/kg
