Rechargeable Battery Pack Safety
With very little care, you can optimize the battery life and maximize the lifespan of
the battery. Most importantly, use only the equipment in its ideal operating
temperature (as described in 1.5 Specifications) –do not leave it in a hot trunk during
the summer.
Important Terms toUnderstand
“Battery life” means the time the equipment will run before it must be recharged
(sometimes this is also called “playtime” or “runtime”).
“Battery lifespan” means the total amount of time your battery will last before it
must be replaced.
Using the Equipment for the FirstTime
Be sure to fully charge (approx. 4 hours) the equipment when charging the
equipment for the first time.
Long-Term Storage & Maintenance
If you are putting away the battery for more than three months, it is
recommended that the battery should be stored separately and fully

Preface
charged, and get recharged every three months. If you store an uncharged
battery, it could fall into a deep worn-out state which would render it incapable of
holding any charge. Be sure to store the equipment and battery at the proper
temperature (as described in 1.5 Specifications).
BatteryLifespan
The removable batteries for the equipment are designed to retain up to 80% of
their original capacity after 300 charging and recharging cycles when properly
maintained. You may choose to purchase new battery when it no longer holds
the sufficient charge that meets your needs.
The lithium-ion battery is currently one of the most popular battery packs. The
best advantage is that it has no memory effect, so users needn’t worry about that
issue. Users can charge the battery anytime whether it is fully drained or not.
However, it’s recommended that users drain the batteryuntil the system shows
power shortage warning and then recharge the battery.
Doingsoishelpfultothereliabilityofyourbattery.
Don’tusethebatterypackasapowersupplyforotherequipment.
Don’t expose the battery to elevated heat situations such as underdirect
sunlight in a car or nearfire.
Don’t disassemble the battery, or the battery leakage might cause skin or eye
injury. If electrolyte leaking from the battery contacts your skin or clothing,
immediately flush it with running water. If it splashes into eye,
rinsetheeyeatleast15minuteswithcleanwaterandthenseekmedical attention.
Toavoid battery leakage or explosion, don’t discard the battery intowater

Cleaning Tools
Although many companies have created products to help improve the process of
cleaning your devices and peripherals, users can also use household items to clean
their devices and peripherals. Below is a listing of items you may need or want to use
while cleaning your devices or peripherals. Keep in mind that some components in
your device may only be able to be cleaned using
aproduct designed for cleaning that component, if this is the case it will be
mentioned in the cleaning.
• Cloth: A piece of cloth is the best tool to use when rubbing up a component.
Although paper towels or tissues can be used on most hardware as well, we
still recommend you to rub it with a piece ofcloth.
• Water or rubbing alcohol: You may moisten a piece of cloth a bit with some
water or rubbing alcohol and rub it on the device. Unknown solvents may
be harmful to the plasticsparts.
• Vacuum cleaner: Absorb the dust, dirt, hair, cigarette particles, and other
particles out of the device can be one of the bestcleaning

Preface
methods. Over time, these items can restrict the airflow in a device and
cause circuitry to corrode.
• Cotton swabs: Cotton swaps moistened with rubbing alcohol or water are
excellent tools for wiping hard to reach areas in your keyboard, mouse, and
otherlocations.
• Foam swabs: Whenever possible, it is better to use lint-free swabs such as
foamswabs.
Recommended Cleaning Procedures

2. Close operatingsoftware
3. Turn off theequipment
4. Remove allperipherals
5. Disconnect the powercable
6. Proceed toclean.
Disposing of the Equipment
Within the EuropeanUnion
EU-wide legislation, as implemented in each Member State,

waste.
This includes monitors and electrical accessories, such as signal cables or power
cords. When you need to dispose of your display products, please follow the
guidance of your local authority, or ask the shop where you purchased the
product, or if applicable, follow any agreements made between yourself. The
mark on electrical and electronic products only applies to the current European
Union Member States.
