Battery information

Note that a new battery's full performance is achieved only aft er two or three complete charge and discharge cycles!

The battery can be charged and discharged hundreds of times but it will eventually wear out. When th e operatin g ti me (talk- time and s tandby time) i s noticeably shorter than normal, it is time to buy a new battery.

Use only batteries approved by the phone manufacturer and recharge the battery only with the chargers approved by the manufacturer. Unplug the charger when not in use. Do not leave the batte ry connected to a charger for longer than a week, since overchargi ng may shorten its lifetime. If l eft unused a fully charged battery will discharge itself over time.

Temperature extremes can affect the ability of your battery to charge. For good operation times with Ni-Cd/NiMh batteries, discharge the battery

from time to time by leaving the produc t switched on unt il it t urns itsel f off (or by using the battery discharge facility of any approved accessory available for the product). Do not atte mpt to discharge t he batt ery by any othe r means.

Use the battery only for its intended purpose. Never use any charger or battery which is damaged. Do not short-circuit the ba ttery. Acc idental short-ci rcuiting can occur when a

metallic object (coin, clip or pen) ca uses direct connection of t he + and - terminals of the battery ( metal strips on the battery) fo r example when you c arry a spare battery in your pocket or purse. Short- circuiting the terminals may damage the battery or the connecting object.

Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce the capacity and lifetime of the battery. Always try to keep the battery between 15°C and 25°C (59°F and 77°F). A phone with a hot or c old battery may temporari ly not work, even when th e battery is fully charged. Batt eries' per formance is par ticular ly limit ed in temperatures well below freezing.

Do not dispose of batteries in a fire! Dispose of batteries according to l ocal regulations (e.g. recycling). Do not dis-

pose as household waste.

Care and Maintenance

The product is a product of superior design and cr aftsmanship and should be treated with care. The suggestions belo w will help you to fulfil any warranty obligations and to enjoy this product for many years.

Keep the phone and all its parts and accessories out of the reach of small children.

Keep the phone dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that will corrode electronic circuits.

Do not use or store the phone in dusty, dirty areas. Its moving parts can be damaged.

Do not store the phone in hot areas. High temperatur es can shorten t he lif e of electronic devices, damage batteries, and warp or melt certain plastics.

Do not store the phone in cold areas. When it warms up (to its normal temperature), moisture can form inside, which may damage electronic circuit boards.

Do not drop, knock or shake the phone. Rough handling can break internal circuit boards.

Do not use harsh chemicals, cl eaning solvents, or strong detergents to clean the phone.

Do not paint the phone. Paint can clog the moving parts and prevent proper operation.

Use only the supplied or an approved replacement antenna. Unauthorised antennas, modifications or att achments could damage the phone and may violate regulations governing radio devices.

All of the above sug gestions apply equal ly to the produc t, battery, ch arger or any accessory.
