Safety and precautions
Computer components and electronic circuit boards can be damaged by discharges of static
electricity. Working on computers that are still connected to a power supply can be extremely
dangerous. Follow these guidelines to avoid damage to the computer or injury to yourself.
• Always disconnect the unit from the power outlet.
• Leave all components inside the static-proof packaging that they ship with until they are ready
for installation.
• After replacing optional devices, make sure all screws, springs, or other small parts are in place
and are not left loose inside the case. Metallic parts or metal flakes can cause electrical shorts.
CAUTION
Only qualified personnel should perform repairs on the DC1000. Damage due to
unauthorized servicing is not covered by the warranty. Please contact your
VariQuest™ Dealer for all service and repair needs.
WARNING
If the LCD breaks and fluid gets onto your hands or into your eyes, immediately wash
with water and seek medical attention.
WARNING
The inverter card has high voltage. Do not touch the inverter card while power is con-
nected to the DC1000. Unplug the power cord before attempting to replace any part.
CAUTION
To prevent static damage to components, wear a grounded wrist strap. Alternatively,
discharge any static electricity by touching the bare metal chassis of the unit case or
the bare metal body of any other grounded appliance.
CAUTION
Hold electronic circuit boards by the edges only. Do not touch the components on the
board unless necessary. Do not flex or stress the circuit board. Do not hold
components such as a processor by its pins; hold it by the edges.
