Use the following procedure to replace the battery when the previous battery
has become completely discharged. You must complete this procedure within
five minutes after turning OFF the power to the CPU Unit to ensure memory
backup.
1. We recommend replacing the battery with the power OFF to prevent the
CPU Unit's sensitive internal components from being damaged by static
electricity. The battery can be replaced without turning OFF the power sup-
ply. To do so, always touch a grounded piece of metal to discharge static
electricity from your body before starting the procedure.
2. After replacing the battery, connect a Programming Device and clear the
battery error.
Procedure
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 upper left of 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 cov-
er.
