notebook in a car trunk on a hot day. Trunk temperatures can reach 140°
F, beyond the safe range for the WinBook notebook. Do not leave the
unit sitting in direct sunlight in your car on a hot day. The heat can cause
system damage. Also be careful when shipping or storing your WinBook
notebook so that it is not exposed to high or low temperatures. The
batteries will not operate as well under extremes of temperature. They
are specified to work from 41° to 95° F (5° to 35° C). Running your
WinBook notebook in temperatures below 41° F or above 95° F will
reduce the battery life. If a battery module is left in the sun and gets quite
hot, it is apt to fail to charge. This is due to a safety switch in the battery
module that is aimed at preventing over-heating due to over-charging.
Once the battery cools down, you will be able to charge it. In extremely
cold weather, you may find that it takes longer for the battery to charge
or that it does not fully charge.
Slots and openings in the system are for ventilation purposes. Do not
obstruct or cover these openings or the system could overheat. Do not
place the system in close proximity to a source of heat or a source of dust.
Protect your modem. Be aware that phone systems can be either analog or
digital. Your modem is designed to work on an analog phone system. Most
residential telephones are analog. Digital phone systems typically involve
building–or company–specific PBX (Private Branch eXchange) systems.
Some PBX systems can use voltages that will damage an analog modem.
Before you hook up your modem in a hotel or at a new company, check
with the facilities manager. To find an analog line, you might look for
a fax machine. Your WinBook X Series notebook has built-in circuitry
protection for the modem in your system. This circuitry will help protect
your system from electrical damage, but it is still recommended that you
locate an analog line where possible. Note that there are products available
that will support analog modems on digital PBXs.
