the supplied, three-conductor ac power cable. The
power cable must be plugged into an approved three-

all accessible conductive parts (including control knobs)
can render an electric shock. The power jack and
mating plug of the power cable must meet IEC safety
standards.

Do not operate the instrument in the presence of
flammable gases or fumes. Operation of any electrical
instrument in such an environment constitutes a definite
safety hazard.

personnel. Component replacement and internal
adjustments must be made by qualified maintenance
