Important User Information

Power supply

• Connect the AC power adapter of the charging unit only to the designated power sources as marked on the charger.

• 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.

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 talkand 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.

• The bat teries 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 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.
