these requirements.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must be connected to
an electrical ground. The instrument is equipped with a three-conductor ac power
cable. The power cable must either be plugged into an approved three-contact
electrical outlet or used with a three-contact to two-contact adapter with the
grounding wire (green) firmly connected to an electrical ground (safety ground) at
the power outlet. The power jack and the mating plug of the power cable meet
International Electrotechnical Commission (IEC) safety standards.

eration of any electrical instrument in such an environment constitutes a definite
safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must not remove instrument covers. Component replacement
and internal adjustments must be made by qualified maintenance personnel. Do not
replace components with power cable connected. Under certain conditions, dan-
gerous voltages may exist even with the power cable removed. To avoid injuries,
always disconnect power and discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE

rendering first aid and resuscitation, is present.
