5. Proper phone maintenance.
Proper use of the battery
Battery in this device can be charged with a charger. If the battery level is low, charge
it. To prolong battery life, let it discharge beneath 20% of the battery capacity before
connecting the charger and charge it up to 100%. If not used, unplug the charger from
the phone and power grid. Overcharging or leaving in a too low/too high temperature
or within magnetic field may shorten battery life cycle. The temperature of the battery
has an impact on its charging cycle. Cool the battery or raise its temperature so that
it is similar to the room temperature (approx. 20°C/68°F). If the battery temperat
ure
exceeds 40°C/104°F the battery must not be
charged! Use the battery only according
to its intended purpose. Do not use a damaged battery. Do not throw the battery into
flames! Do not throw a worn-out battery
–
send it or return it to an authorized recycling
point.
Device maintenance
Keep your phone and accessories out of reach of children in a dry place, away from
moisture, for extended the life of your phone. Avoid using the phone in high and low
temperatures; it can shorten the life of phone electronic components, melt the plastic
parts and destroy the battery. It is recommended that the phone is not used at
temperatures higher than 40°C/104°F.
Do not try to disassemble the phone. Tampering with its structure in an unprofessional
manner may cause serious damage to the phone or destroy it completely.
For cleaning use only a dry cloth. Never use any agent with a high concentration of
acids or alkalis. Use the original accessories only. Breaking those rules might cause a
loss of warranty.
