remove external voltage sources before touching components.
CAUTION

Do not attempt internal service or adjustment unless another person,
capable of rendering first aid and resuscitation, is present.

NOTE
Instruments that appear damaged or defective should be made inoperative and
secured against unintended operation until they can be repaired by qualified
service personnel.
