3. Apply power to the external power supply.
4. Confirm that the RMC is receiving power by observing the power on sequence information scrolling
on the LCD (see details in section 5.1). When the DATE/TIME display, the sequence is complete.
5. If the power on sequence fails to initiate or complete, press the reset button shown in

Lithium battery

The lithium battery serves to retain operation of the real time clock with the lithium battery backup
switch. The switch is located between the TFIO ports and is accessed by a slot in the housing. Lift the
cover over the TFIO ports to view the switch settings. The two settings are:
 Enable: The switch is on. The lithium battery backs up the real time clock. If power is lost or
disconnected, the real time clock continues to operate until the lithium battery is depleted.
 Disable: The switch is off. The lithium battery does not back up the real time clock.
To ensure the lithium battery is enabled, insert a small screwdriver in the slot and move the switch to
the ENABLE position as shown in
