Care And Maintenance - Nokia HF-300 User Manual

Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic
object such as a coin, clip, or pen causes direct connection of the positive (+) and negative (-)
terminals of the battery. (These look like metal strips on the battery.) This might happen,
for example, when you carry a spare battery in your pocket or purse. Short-circuiting the
terminals may damage the battery or the connecting object.
Leaving the device 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 device with a hot or cold battery may not
work temporarily, even when the battery is fully charged. Battery performance is particularly
limited in temperatures well below freezing.
Do not dispose of batteries in a fire as they may explode. Batteries may also explode if damaged.
Do not dismantle or shred cells or batteries. In the event of a battery leak, do not allow the
liquid to come in contact with the skin or eyes. In the event of such a leak, flush your skin or
eyes immediately with water, or seek medical help.

Care and maintenance

Your device is a product of superior design and craftsmanship and should be treated with
care. The following suggestions will help you protect your warranty coverage.
• Keep the device dry. Precipitation, humidity, and all types of liquids or moisture can
contain minerals that will corrode electronic circuits. If your device does get wet, remove
the battery, and allow the device to dry completely before replacing it.
• Do not use or store the device in dusty, dirty areas. Its moving parts and electronic
components can be damaged.
• Do not store the device in hot areas. High temperatures can shorten the life of
electronic devices, damage batteries, and warp or melt certain plastics.
