Cleaning Recommendations
CAUTION
Failure to follow these rules may melt, distort, or dull the
finish of the case, blur lettering on the labels, or cause
equipment failures.
Remove power, batteries and all cables before cleaning the equipment.
Wipe the equipment with a soft, lint-free cloth and one of the following
approved cleansers:
„
Cidex solution
„
Sodium hypochlorite bleach (diluted)
„
Mild soap (diluted)
In addition, follow these guidelines:
„
Always dilute cleaning solutions per manufacturer’s
recommendations.
„
Wring excess solution from the cloth before wiping the equipment.
Do not drip any liquid into open vents, plugs, or connectors.
„
Always wipe off cleaning solutions with a clean, dry, lint-free cloth or
let air dry for at least 15 minutes.
„
Do not let fluid “pool” around connection pins. If this happens, blot
dry with a cotton swab or soft cloth.
„
Use compressed air to remove dust from connectors and vents.
Battery
General
The lithium-ion battery is a rechargeable battery containing lithium-ion
cells. Each battery contains an integrated electronic fuel gauge and a
safety protection circuit. The processor within the equipment
communicates with both the battery and the charger via the SMBUS 2-
wire serial interface.
The following are the key points you should know about lithium-ion
battery technology:
„
The battery will discharge on its own, even when it is not installed in
the equipment. This discharge is the result of the lithium-ion cells
and the bias current required for the integrated electronics.
„
The self-discharge rate doubles for every 10°C (18°F) rise in
temperature.
„
The capacity loss of the battery degrades significantly at higher
temperatures.
„
As the battery ages, the full-charge capacity of the battery will
degrade and be permanently lost. As a result, the amount of charge
that is stored and available for use is reduced.
The following terms are used to define the battery capacity:
