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 PT-5700. Damage due to
unauthorized servicing is not covered by the warranty. If you are not confident of
installing a hard drive or CompactFlash card, we recommend that you refer the
job to qualified personnel.
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
connected to the PT-5700. Unplug the power cord before attempting to replace
any part.
CAUTION
To prevent static damage to components, wear a grounded wrist strap. Alterna-
tively, 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 it is necessary to do so. Do not flex or stress the circuit
board. Do not hold components such as a processor by its pins; hold it by the
edges.
