11 Correctly Using the iPAD
11.1 Using the main battery
To prevent deterioration, do not store the main battery for a long time when it is fully charged. For
long-term storage, remove the battery from the IPAD when it is about 50% charged and store it at room
temperature.
If the battery has not been used for a long time, recharge it.
Be careful not to short-circuit the battery terminals with a necklace or other metallic object.
Do not heat the battery or throw it into a fire.
Do not leave the battery in a car exposed to sunlight or in direct sunlight.
Do not allow the battery to become wet.
Do not apply a strong shock to the battery. Do not drop the battery.
Using the iPAD at low temperatures (below 50
o
F)
−
At low temperatures (below 50
o
F), the iPAD does not operate as long as it does at room temperature.
In an environment of 50
o
F, operating time is about 70% of that at room temperature, and in an
environment of 32
o
F, it is about 50% (new battery used).
If operation in a low-temperature environment is possible, review charging procedures and operation.
−
In operation at low temperatures (below 50
o
F), replacing the battery with one that is only partially
charged will result in a very short operating time. Be sure to replace the battery with a fully charged
one.
−
Keep a spare battery warm until you use it by, for example, putting it in your pocket. If you warm a
battery with a body warmer, be careful that the battery does not come into direct contact with the body
warmer.
If a message indicating that charging is required (battery status message) is displayed, promptly charge
the battery or replace the battery with a spare battery.
Be careful that no dust, sand, or other foreign matter enters the terminal section while you are using the
iPAD. If any foreign matter gets in, completely remove it using a soft-tipped cotton swab or gauze, then
repeat several times inserting the iPAD into the charger or device and then removing it.
The iPAD may not charge if the terminals are dirty.
Despite complete charging, the battery naturally discharges little by little as time passes. If possible,
charge the battery again just before using it (within one or two days).
Store the battery in as cool a place as possible and charge it at an ambient temperature of 50
o
F to 86
o
F.
Doing so will increase the life of the battery.
11.2 Using the auxiliary battery
Auxiliary battery alarm message
A warning message appears in the center of the screen if the voltage of the auxiliary battery drops or the
auxiliary battery is not connected. The programs and data in memory will be lost if you replace the main
battery while this message is displayed.
Immediately charge the auxiliary battery.
