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.

•

T

he 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 b5°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.
