Warnings
To prevent re, or shock hazard, do not expose your SP20 to rain or
moisture. Do not place containers with liquid on top of unit.
This unit contains voltages which can cause serious injury or death. Do
not operate with cover removed. Refer servicing to your authorized Audio
Research dealer or other qualied personnel.
The detachable power cord on your SP20 is equipped with a heavy gauge,
3-conductor cable and a standard three-prong grounding plug. For
absolute protection, do not defeat the ground power plug. This provides
power line grounding of the SP20 chassis to provide absolute protection
from electrical shock.
For continued protection against re hazard, replace the fuse only with the
same type and rating as specied at the fuse holder.
The appliance coupler at the rear of this unit must be accessible for
emergency power disconnect.
A note about packaging...
Save all packaging in a dry place away from re hazard. Your SP20 preamplier
is a precision electronic instrument and should be properly cartoned any
time shipment is made. You may not have occasion to return your unit to
the factory for service, but if that should prove necessary, or other occasion
requiring shipment occurs, the original packaging will protect your SP20
from unnecessary damage or delay.
