Disposal of the product
• Your product should not be placed in
municipal waste. Please check local
regulations for disposal of electronic
products.
Power supply
• Connect the AC power adapter of the charging unit
only to the designated power sources as marked on
the charger.
• Make sure the AC power supply is positioned so
that it will not be subjected to damage or stress.
• To reduce risk of electrical shock, unplug the
chargers from any power source before attempting
to clean or move it.
• The AC power adapters must not be used outdoors
or in damp areas.
• Never modify the cord or plug. If the plug will not fit
into the outlet, have a proper outlet installed by a
qualified electrician.
• Limit the distance between the mains socket and
the cordless phone when charging for easy
accessibility.
• As an energy saving measure, disconnect the
charger from the main socket after charging.
• When unplugging the mains adapter from the
power outlet, make sure that your hands are dry
and ensure that you hold the solid portion of the
mains adapter.
• Do not pull on cables.
• See the complete User Guide for available power
adapters.
Charging and batteries
• Please read carefully the following
important precautions before the first
time use of the batteries. Make sure to
understand and observe all cautionary
instructions stated, so as to avoid any
possible safety hazards that are caused
by any misuse, misapplication or damage to
batteries.
• Only use batteries, mains adapters or desk and rack
chargers which have been specifically designed for
use with your product.
• Use of power sources not explicitly recommend-
ed may lead to overheating, reduced battery per-
formance, distortion of the equipment and fire or
other damages.
• The phone is equipped with Lithium Li-polymer/
Li-Ion battery. In a complex infrastructure, the talk-
and standby time may differ, due to the con-
sequence of the increase in signaling.
• The battery must always be completely charged
(minimal 4 hours) before first time use.
• The battery in your product is designed to withstand
many charge cycles.
• Use only the recommended charging equipment.
• Improper charging can cause heat damage or even
high pressure rupture.
• Observe proper charging polarity.
• Do not solder lead wires directly onto the battery.
• Do not allow water to come into contact with the
battery.
• The battery is replaceable, however it is not the
intention to do this frequently.
• Only charge the battery when placed in the phone.
• Use only the specified battery-packs for your
product.
• Never heat or dispose of the battery into a fire,
which, or else, may cause leakage, burst or fire.
• Remove the carrying case from the product while
in charger.
• Do not cover the product while being charged.
Do not charge the phone in a closed cabinet or
drawer. The charging of the battery is a chemical
process and causes the battery to become warm
during charging. Make sure the environment in
which the phone is charged, is well vented.
• The cordless phone can be charged either when
switched on or off.
• Do not connect the battery's positive and negative
leads altogether in any circumstances.
• Do not strike or drop the battery. It may cause
damage to the battery.
• Do not charge the battery below +5°C
(+41°F). Be sure to charge the battery
between +5°C and +40°C (+41°F and
104°F). Charging beyond these
conditions may impair the battery
performance and shorten the life cycle.
• Do not use battery packs from different types,
brands or of different capacities.
• The battery is to be stored in a dry cool place, with
the ambient temperature of approx. +25°C (+77°F)
for best performance.
• The battery continues to discharge a minimal
portion of its power, even if the product is switched
off or the battery is removed.
• Dispose the battery in accordance with all local
regulations, applicable in your country.
