Section 13-2
Procedure
1,2,3...
1.
Turn OFF the power to the CPU Unit.
or
If the CPU Unit has not been ON, turn it ON for at least five minutes and
then turn it OFF.
Note
If power is not turned ON for at least five minutes before replacing the
battery, the capacitor that backs up memory when the battery is re-
moved will not be fully charged and memory may be lost before the
new battery is inserted.
2.
Open the compartment on the CPU Unit and carefully draw out the battery.
3.
Remove the battery connector.
4.
Connect the new battery, place it into the compartment, and close the cover.
!WARNING
Never short-circuit the battery terminals; never charge the battery; never dis-
assemble the battery; and never heat or incinerate the battery. Doing any of
these may cause the battery to leak, burn, or rupturing resulting in injury, fire,
and possible loss of life or property. Also, never use a battery that has been
dropped on the floor or otherwise subject to shock. It may leak.
!Caution
You must complete this procedure within five minutes after turning OFF the
power to the CPU Unit to ensure memory backup. If the procedure is not com-
pleted within 5 minutes, data may be lost.
!Caution
UL standards require that batteries be replaced by experienced technicians.
Always place an experienced technician in charge of battery replacement.
!Caution
Turn ON the power after replacing the battery for a CPU Unit that has been
unused for a long time. Leaving the CPU Unit unused again without turning
ON the power even once after the battery is replaced may result in a shorter
battery life.
Note
The battery error will automatically be cleared when a new battery is inserted.
