For instructions on returning an SLC 5/03 or 5/04 processor to its default condition,
refer to Allen-Bradley publication number 1747-6.2, SLC 500 Modular Hardware Style
Installation and Operation Manual . For other SLC 500 processors, just unplug the
battery and cycle power. Be aware that this may not be sufficient for SLC 5/01 1K and
4K processors that have a backup capacitor and that this capacitor can take from one
week (1K) to four weeks (4K) to discharge.
