Switch, LED, and Connector
Before programming the System, switch 1-4 should be ON and then power cycle OFF and ON
to initialize the default System database. Once the database has been initialized, switch 1-4
should be placed in the OFF position to protect the database.
After putting the SW2 lithium battery switch ON to protect the RAM/RTC data, install the
option boards to the MBU.
Note:
• The SW2-DIP switch should be turned ON to protect the System database in case of
power failure.
• As needed, replace the batteries with the same or equivalent type recommended by the
manufacturer; the System will not function normally if the battery is incorrectly replaced.
• Dispose of used batteries according to manufacturer instructions and/or local government
regulations.
• The 4th pole of SW1 should be OFF to protect the features being programmed in Admin
programming after the System power up and initialization.
