Caution: This instrument uses 120 or 240 50/60 Hz AC power. Opening the enclosure
door exposes you to potentially hazardous line power voltage which might be pres-
ent on the terminals of plug P3 and P4. Always remove line power before working in
this area. If the relay contacts on P4 are powered from a seperate source from the
line power on P3, be sure to disconnect that power before proceeding. The Shark flip
out door contains only low voltage and is safe to handle.
