Introduction
6. The S88X cabinet has slots for ventilation purposes to prevent
component overheating.
a. Never cover the slots with cloth or any other material.
b. Avoid placing the S88X over radiators or heat registers.
c. Never place the stimulator in an enclosure unless proper
ventilation is provided and all other related precautions taken.
7. Operate the S88X only on the power sources as printed on the panel.
Damage may result from incorrect voltage.
8. The voltage/current output of this general purpose stimulator can be
lethal or cause tissue damage if not used properly by persons trained
in the application intended for this instrument.
9. Note the output of this general purpose stimulator is referenced
to ground, i.e., one terminal of the output is ground. Also all sync
inputs and outputs are also referenced to ground. To obtain stimulus
potentials isolated from ground choose the appropriate Grass
isolation unit.
10. If this stimulator is to be used with an isolation output, use the
proper Grass isolation unit accessory. Contact Grass for application
information in writing.
11. Determination of the safe levels of the stimulation for each
application is the responsibility of the investigator in charge.
12. The investigator in charge is responsible for assuring safe stimulation
levels will not be exceeded.

The included ferrite EMI suppression cores are
required for compliance with EN61326. These should
be attached to each output cable by opening the split
core, then snapping it together over the cable so that
the cable runs through the ferrite core. These should be
placed near the output connector on the S88X.
