Safety Warnings
Warning
Before working on equipment that is connected to power lines, remove jewelry
(including rings, necklaces, and watches). Metal objects will heat up when
connected to power and ground and can cause serious burns or weld the metal
object to the terminals.

made first and disconnected last.

system unless all cards, faceplates, front covers, and rear covers are in place.

the battery only with the same or equivalent type recommended by the
