DIP Switch Positions (SW3)
The MPB also has an eight-position DIP switch, SW3. The default setting is: All ON position.
The function of each switch position is as follows:
Before programming the system, dip switch 8 (database default switch) should be placed in
the on position and power cycled off and on to initialize the system database to default. Once
the database has been initialized, switch 8 should be placed in the off position to protect the
database.

MPB/MISB card in the card slot before removing the RS-232 cable. Failure to perform
this action may result in the MPB/MISB card being pulled from its slot.
