Protection Systems - JEFF ROWLAND CONCERTO Owner's Manual

If you have any questions about the care or cleaning of your
CONCERTO Stereo Preamplifier, please contact your dealer or the
JRDG factory before attempting to clean the chassis. The use of a
cleanser or abrasive to clean the chassis that has not been approved
by the factory will almost certainly damage the finish and will not be
covered under warranty.
NOTE: Cleaner/polish should be applied directly to the cloth and not the chassis.

The CONCERTO Stereo Preamplifier is equipped with internal fuses
for pro tection against excessive AC current draw; however, since no
protection circuitry or system can completely protect a product from
every electrical hazard, certain precautions should be observed. In the
event of severe voltage hazards such as lightning or when the pream-
plifier will not be used for extended periods of time, the preamplifier
should be unplugged from the AC mains to avoid potential damage to
the internal circuitry. All other audio/video system components should
also be disconnected from AC mains power as hazardous voltages
can easily travel throughout an interconnected system.
