household waste. There is a separate
collection system for used electronic
products in accordance with legislation
that requires proper treatment,
recovery and recycling.
Please contact your local authorities
for the correct method of disposal.
By doing so, you will ensure that
your disposed product undergoes the
necessary treatment, recovery and
recycling and thus prevent potential
negative effects on the environment
and human health.
Battery
Connect the power adapter to the
electric supply network and insert the
adapter plug into the power connector
of the device. While charging, the
process is displayed as an additional
lightning symbol in the power icon: . It
is recommended not to disconnect the
device until the battery is fully charged.
When the battery is fully charged,
the power icon on the screen will be
completely filled.
Please remember:
• The battery has to be fully charged
before the first use;
• A new battery reaches its nominal
capacity after two-three full charge/
discharge cycles!
• Lithium batteries are not fit for
extended storage, they are designed
for regular active use;
• Avoid repeated full discharges. They
shorten the battery life. Frequent
charges are more preferable;
• If the device is not used for a long
time, the AC adapter should be taken
out from the electrical mains;
• Do not leave the battery charging for
a long time;
• When not in operation, a fully charged
battery discharges over time.
• Never use a malfunctioning battery or
generic AC adapters. This may lead to
overheating as well as fire.
• Charge the battery fully before
extended period of storage (more
than 1 month). Store the battery at
temperatures from +5°С to +20°С.
• The optimum operation temperature
is from +15°C to +25°C.
• Do not expose the battery to
temperatures below -10°C, as it
shortens the battery life significantly.
• At temperatures below +5°C,
the battery will not charge fully. At
prolonged exposure to heat above
+40°C the rate of discharge greatly
increases.
• Prolonged exposure of the battery to
extremely low or high temperatures,
for example, in a closed automobile in
summer or winter, shortens its capacity
and operating life.
• If the operating time between two
charging cycles (in talk mode as well
as stand-by mode) becomes noticeably
shorter, it means the battery has to be
replaced with a new one.
• Do not dispose of the run-down
batteries together with general
household waste.
