S AFETY I NSTRUCTIONS
• 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.
