High voltages in this equipment can cause serious injury or death. When applying power
during a test, take proper measures to ensure safety of personnel. Never work on
electrical equipment unless there is another person nearby who is familiar with the
operation and hazards to the equipment.
Use extreme care to avoid contacting the fuse or control circuitry other than trimmer
