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 cord 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.

power outlet, make sure that your hands are dry

and ensure that you hold the solid portion of the

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

recommended may lead to overheating, reduced

battery performance, distortion of the equipment

and fire or other damages.

• Cordless phones are equipped with Nickel Metal

Hydride (NiMH) batteries or Lithium Ion Lion

batteries. In a complex infrastructure, the talk-

and standby time may differ, due to the

consequence 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 initial charging of a NiMH battery will cause

the battery to become warm. This is a normal

effect of charging NiMH batteries.

• The batteries are replaceable, however it is not the

intention to do this frequently.

• Only charge the batteries 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 +45°C (+41°F and

113°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.
