Replacement Procedure
Use the following procedure to replace the battery.
Precautions for Safe Use
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 with-
out turning OFF the power supply. To do so, always touch a grounded piece of metal to dis-
charge static electricity from your body before starting the procedure.
After you replace the Battery, connect the Sysmac Studio and clear the Low Battery Voltage
event.
Additional Information
UL standards require that batteries be replaced by experienced technicians. Always place an
experienced technician in charge of battery replacement.

be lost before the new battery is inserted.
