Nokia 1661 - Manual (Page 12)

indicator appears on the display or before any calls can be
made.
Safe removal. Always switch the device off and disconnect the
charger before removing the battery.
Proper charging. Unplug the charger from the electrical plug
and the device when not in use. Do not leave a fully charged
battery connected to a charger, since overcharging may
shorten its lifetime. If left unused, a fully charged battery will
lose its charge over time.
Avoid extreme temperatures. Always try to keep the battery
between 59°F and 77°F (15°C and 25°C). Extreme
temperatures reduce the capacity and lifetime of the battery.
A device with a hot or cold battery may not work temporarily.
Battery performance is particularly limited in temperatures
well below freezing.
Do not short-circuit. 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.
Disposal. Do not dispose of batteries in a fire as they may
explode. Dispose of batteries according to local regulations.
Please recycle when possible. Do not dispose as household
waste.
Leak. Do not dismantle, cut, open, crush, bend, puncture, or
shred cells or batteries. In the event of a battery leak, prevent
battery liquid contact with skin or eyes. If this happens, flush
the affected areas immediately with water, or seek medical
help.
Damage. Do not modify, remanufacture, attempt to insert
foreign objects into the battery or immerse or expose it to
water or other liquids. Batteries may explode if damaged.
Correct use. Use the battery only for its intended purpose.
Improper battery use may result in a fire, explosion, or other
hazard. If the device or battery is dropped, especially on a
hard surface, and you believe the battery has been damaged,
take it to a service center for inspection before continuing to
use it. Never use any charger or battery that is damaged. Keep
your battery out of the reach of small children.
Nokia battery authentication guidelines
Always use original Nokia batteries for your safety. To check
that you are getting an original Nokia battery, purchase it
from a Nokia authorized service center or dealer, and inspect
the hologram label using the following steps:
Authenticate hologram
1
When you look at the hologram on the label, you should
see the Nokia connecting hands symbol from one angle
and the Nokia Original Enhancements logo when
looking from another angle.
2 When you angle the hologram left, right, down and up,
you should see 1, 2, 3 and 4 dots on each side
respectively.
Successful completion of the steps is not a total assurance of
the authenticity of the battery. If you cannot confirm
authenticity or if you have any reason to believe that your
Nokia battery with the hologram on the label is not an
authentic Nokia battery, you should refrain from using it, and
take it to the nearest Nokia authorized service center or
dealer for assistance.
For additional information, refer to the warranty and
reference leaflet included with your Nokia device.
