TabletKiosk eo a7400 - Manual (Page 11)

In general, running the system until both battery indicators are blinking, typically this is when
the batteries are down to just below 10% charged, and then fully charging the batteries (full
discharge/charge cycle) will ensure the accuracy of the battery status gauges and prolong the
batteries' charge efficiency.
You do not need to plug in the system when only one of the battery indicators are blinking, as
the other battery may have plenty of charge remaining. Generally, waiting until they are both
blinking before charging is preferred.
When there is only one minute of battery charge remaining, the computer will suspend its
current state to the hard drive and power off (hibernate) to prevent data loss. To resume your
work, either swap in charged batteries or plug in the AC adapter and turn the system back on.
Cleaning and Caring for Your System
Never use household cleaning supplies or glass cleaner with ammonia to clean the case or the
LCD screen. Additionally, you shouldn't ever spray anything directly on the Tablet PC while it is
powered on and running.
A can of compressed air can be used to remove dust and other particulate matter from crevices,
vents and I/O ports. Compressed air is also good for cleaning dust from the non-slip surface of
the eo a7400's top case.
Cleaning the LCD screen
Gently wipe the surface using a clean, dry microfiber cloth. Do not use excessive pressure. Using
your breath in conjunction with the microfiber cloth, as you would to clean the lenses on a pair
of eye glasses, is very effective.
To remove really tough marks and smudges:
1. Spray a small amount of LCD cleaner, water or a mixture of water and isopropyl alcohol
(70/30 mix) on a microfiber cloth. The cloth should be damp, not saturated or dripping.
CAUTION: Do not spray or apply any liquids directly onto the Tablet PC. Always apply the solution to your
microfiber cloth first, not directly on the parts you are cleaning.
2. Gently wipe the display surface. Use only as much pressure as necessary to remove the
smudge. Wipe in small circular motions.
Cleaning Cloth
To clean your display, we recommend using the microfiber cloth that came with your system or
a similar double-sided microfiber cloth. They are extremely soft, non-abrasive, and are non-
electrostatic which is ideal for cleaning LCD screens and other computer components.
Cleaning Solutions
For tough, greasy marks or smudges, use water, high purity isopropyl alcohol, or a cleaning
solution specifically made for cleaning LCD monitors. Be sure not to use cleaners that contain
Acetone, Ethyl Alcohol, Ethyl Acid, Ammonia, or Methyl Chloride.
Storing the System Long-Term
If you don’t plan on using your eo a7400 for more than four months, TabletKiosk recommends
that you remove the Lithium-Ion battery and store it with approximately a 50-70% charge. If
you store a Lithium-Ion battery when it’s fully discharged, it could fall into a deeply discharged
state which renders it incapable of holding any charge. Conversely, if you store the battery fully
charged for an extended period of time, the battery may experience some loss of charging
capacity, meaning it will have a shorter life. Be sure to store your Tablet PC and batteries in a dry,
cool location to prevent damage due to extreme temperatures and/or condensation.
