Using Your Computer 2-21
„
Disconnect your system from telephone and power lines
when an electrical storm threatens. If you have a
fax/modem, lightning can travel in on the phone line and
damage both the fax/modem and the system unit.
Lightning can also travel in on power lines and damage
your monitor and system unit.
„
Be sure that system power is off before you connect or
disconnect a cable. Never make cable changes when the
system power is on. To do so could damage your system
and its peripherals.
„
Use appropriate virus detection software regularly to
protect your system from computer viruses.
If you plan to use software programs other than
NECCSD-supplied software, NECCSD strongly
recommends that you take the necessary steps, such as
virus checks, to protect your system.
Use Setup options to set up an automatic reminder to
run a virus check (see “Power Menu” in Chapter 4).
„
Place your computer away from direct sunlight and
extreme hot and cold temperatures.
The recommended operating environment is from 50
°
F
to 95
°
F (10
°
C to 35
°
C).
The recommended non-operating environment (shipping
or storage) is from 14
°
F to 158
°
F (-10
°
C to 70
°
C).
„
After turning off power, wait about five seconds for the
hard disk to spin down before you power on again.
„
Be sure that nothing is placed on top of your system
power cables.
„
Prevent dust from entering your system by covering it
when it is not in use.
