Control Chassis. The rocker-type switch is integrated in the 15A female IEC receptacle
module, mounted in an inset area immediately to the left of the twin battery holders.
When the master power switch is moved to the 'on' position, the
tests its circuitry for several seconds, then enables the active inputs and
PREAMPLIFIER
outputs. The preamplifier is best left powered on indefinitely to ensure optimum
operating characteristics, and to help maintain the batteries in a fully charged condition.
NOTE: IF THE CRITERION PREAMPLIFIER IS IN RUN-ON BATTERY MODE, IT WILL CONTINUE TO
OPERATE EVEN WHEN THE POWER SWITCH IS TURNED-OFF.
