SAFETY INSTRUCTIONS

Do not expose a battery to an open flame. This could cause the battery to explode.

Never carry or store the battery together with electrically conducting objects (neck chains, pencil leads, etc.)

If you ever notice liquid leaking out, unusual odour, build-up of heat, discolouration, deformation or any other abnormal condition when you use, charge or store the battery, remove the battery immedi- ately from the handset and keep it away from naked flames.

The battery fluid can damage your sight. If at any time battery fluid accidentally gets into your eyes, rinse your eyes immediately with clean tap water and contact a doctor.

Do not allow the metal contacts on the battery to touch another metal object. This could short-circuit and damage the battery.

Do not leave a battery where it could be subjected to extremely high temperatures, such as inside a car on a hot day.

Use the Desktop Charger or the wall mounted Charging Rack for charging. Charge the battery for at least one hour the first time you use the battery. Note that the wall mounted charger with a battery pack adapter has to be used if the battery alone is to be charged.

Do not charge a battery when the ambient room temperature is above 40 ºC or below +5 ºC (above 104º F or below 41 ºF).

Do not attempt to take a battery apart.

Do not disconnect the battery unless it needs to be replaced.

Turn off the telephone before removing the battery.

Unplug the battery charger from a power source before cleaning the phone to reduce risk of electric shock.

Only charge the battery when it is placed in the phone.

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 it is 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 ventilated.

The cordless phone can be charged either when switched on or off.

Do not, under any circumstance, connect the battery's positive and negative leads altogether.
