Observe the following Cautions and Warnings when you change an FRU or other component.
WARNING:
1. Turn off the power and disconnect the AC power cord or AC adapter
from the power source; exposure to electric shock hazards may occur.
2. Batteries in the computer retain electrical charge, so there is danger
of electrical shock even when the computer is disconnected from an AC
power source. To reduce the risk of accidental electric shock, remove
any metal jewelry or accessories such as necklaces, bracelets or rings..
Never work with wet or damp hands.
3. The 610CT contains many sharp edges and corners, so be careful not
to injure yourself.
CAUTION:
1. When you change a component, be sure the replacement component
meets the required specifications. To avoid any risk of damage to the
computer, never use foreign parts.
2. To avoid any risk of short-circuit, fire, or other internal damage,
never allow any metal objects such as screws or paper clips to fall into
the unit. Be sure to replace screws with the same size as those removed.
Screw sizes are listed in the corresponding figures. Make sure all screws
are securely fastened. Loose screws can cause short circuits, resulting in
heat, smoke, or fire.
3. To reduce the risk of accidental electric shock before lifting out an
FRU or other component, make sure all cables to the component have
been disconnected.
4. Be sure to use the correct AC adapter. Use of the wrong adapter
could cause reverse polarity resulting in smoke, fire, or other equipment
damage.
5. To avoid the risk of accidental electric shock, make sure that all
replacement components meet the specifications for the computer and
that all cables and connectors are securely fastened.
