cause

harmful

interference

to the equipment

and/or system

or

cause

the

equipment

and/or

system

to

fail

to perform

its

intended

function

or degrade its

intended

performance.

Therefore,

during

the

operation of

the

eguipment

and/or

system, if there

is any undesired deviation from

its intended operational performance, you must avoid, identify

and

resolve the adverse

electromagnetic effect before continuing to use the equipment

and/or

system.

The following describes some common interference sources and remedial actions:

1.

The equipment

and/or

system

is not

grounded:

For AC powered equipment and/or system, use the provided grounding cable to connect the

equipotential

terminal

of

the

equipment to

the

grounding

system of the

facility.

2.

Strong

electromagnetic interference from a nearby emitter source such

as

an

authorized

radio station or cellular phone:

Install

the equipment

and/or

system
