6. Precautions
6.1 Handling Precautions
Precautions for short-term storage (1 to 2 days)
• If the IT-3100 remains unused for a long period including Saturday and Sunday, before starting
holiday replace the battery pack if installed in the terminal with a fully charged battery pack. This
will conserve the built-in memory backup battery and ensure retention of data on the terminal.
• If there is a possibility of the above or operator error (e.g., a fully charged battery has not been
inserted), practice system operation that maintains a backup to avoid loss of data due to
consumption of the batteries.
Precautions for long-term storage (over one week)
• Prior to a long-term storage (over one week), always back-up data in the terminal to other
memory storage device. In addition, remove the lithium-ion battery pack before storage. This can
minimize overly discharging the installed battery and minimize consumption of the memory
backup battery.
• Do not store the removed battery pack at high temperature. Otherwise, it will discharge at an
accelerated rate. Note that the capacity after the battery if it is not used for 10 days at 60°C will be
65%, and that after 20 days at 60°C will be 55%.
Battery Pack
• Never contact the “+” and “-“ terminals with metal objects such as a wire. Also, do not carry and
store the battery with a metal necklace or hair pin. Otherwise, the battery pack may be
short-circuited resulting in an excessive current and causing the battery to become hot, smoke,
explode or catch fire.
• Neither dispose of the battery pack into a fire nor heat it. The insulation may be burnt, the gas
exhaust valve or safety mechanism may be damaged, or the internal electrolyte may ignite
causing the battery pack to become hot, generate smoke, explode, or ignite.
• Neither leave nor use the battery pack in a place with a high temperature (over 80°C) or close to a
fire or hot stove. Should the resin separator be damaged due to excessive heat, the battery pack
may be short-circuited causing it to become hot, generate smoke, explode, or ignite.
• Do not soak the battery pack in fresh water or sea water. If the protection means incorporated in
the battery pack is damaged, the battery pack may become hot, smoke, explode, or ignite.
• Do not attempt to charge the battery close to a fire, in direct sunlight, or in a car parked in the sun.
A heated battery pack will trigger the internal hazard protection means to stop the charging
function. Or, the protection means may be damaged and the battery may be charged with an
excessive current or voltage, or have abnormal chemical reactions induced to cause it to become
hot, smoke, explode, or ignite.
• Do not stick a pin or nail in the battery pack. Neither hit it with a hammer nor stamp it. If this is
done, the battery pack may be broken or deformed resulting in a short circuit and causing it to
become hot, smoke, explode, or ignite.
• Do not hit or throw the battery pack. If the protection means incorporated in the battery pack is
damaged, the battery pack may be charged with an excessive current or voltage, or have abnormal
chemical reactions induced to cause it to become hot, smoke, explode, or ignite.
• Never use a battery pack that is significantly damaged or deformed. It may become hot, smoke,
explode, or ignite.
