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 instal- •
lation.
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.
If the LCD breaks and fluid gets onto your hands or into your eyes,
immediately wash with water and seek medical attention.
WARNING
CAUTION
Only qualified personnel should perform repairs on the PT-6910 Series.
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.
The inverter card produces high voltage. Do not touch the inverter card
while power is connected to the machine. Unplug the power cord before
attempting to replace any part.
WARNING
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 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.
