Nokia 2720 User Guide
Always keep the battery between 59°F and 77°F (15°C and 25°C) for optimal performance.
Extreme temperatures reduce the capacity and lifetime of the battery. A device with a hot or
cold battery may not work temporarily. Accidental short-circuiting can happen when a metallic
object touches the metal strips on the battery. This may damage the battery or the other
object.
Do not dispose of batteries in a fire as they may explode. Obey local regulations. Recycle when
possible. Do not dispose as household waste.
Do not dismantle, cut, crush, bend, puncture, or otherwise damage the battery in any way.
If a battery leaks, do not let liquid touch skin or eyes. If this happens, immediately flush the
affected areas with water, or seek medical help. Do not modify, attempt to insert foreign
objects into the battery, or immerse or expose it to water or other liquids. Batteries may
explode if damaged.
Use the battery and charger for their intended purposes only. Improper use, or use of
unapproved or incompatible batteries or chargers may present a risk of fire, explosion, or other
hazard, and may invalidate any approval or warranty. If you believe the battery or charger is
damaged, take it to a service centre or your phone dealer before continuing to use it. Never
use a damaged battery or charger. Only use the charger indoors. Do not charge your device
during a lightning storm.
SMALL CHILDREN
Your device and its accessories are not toys. They may contain small parts. Keep them out of
the reach of small children.
MEDICAL DEVICES
Operation of radio transmitting equipment, including wireless phones, may interfere with
inadequately shielded medical devices’ function. Consult a physician or the medical device’s
manufacturer to determine if it is adequately shielded from external radio energy.
IMPLANTED MEDICAL DEVICES
To avoid potential interference, manufacturers of implanted medical devices recommend a
minimum separation of 15.3 centimeters (6 inches) between a wireless device and the medical
device. Persons who have such devices should:
• Always keep the wireless device more
than 15.3 centimeters (6 inches) from the
medical device.
• Not carry the wireless device in a breast
pocket.
• Hold the wireless device to the ear
opposite the medical device.
• Switch the wireless device off if there is
any reason to suspect that interference is
taking place.
• Follow the manufacturer directions for the
implanted medical device.
