bulb, place your index finger across the hole on the
underside of the tube and in contact with the bulb. Use
the ball of your finger to rotate the bulb out of its
socket. Then remove the bulb from the front of the light
tube. Put a new bulb in the tube, rotate it with your
finger from the hole in the bottom of the tube and
replace the light tube cap(s).
NOTE: The caps and light tubes become quite warm to
the touch in normal operation. To avoid burning your
fingers, allow the cap to cool completely before
unscrewing it. If you find that the heat from the tubes is
excessive, try reducing the setting of the dimmer knob.
As an alternative, you may substitute four-watt bulbs or
even colored Christmas tree bulbs.
The Tape Trick: In cases where the bulb is still warm, or
too tight to unfasten with your fingers, a piece of duct or
gaffers tape about 2 inches square can aid in the bulb
removal. Simply pinch about a quarter inch of the center
portion of tape together, and place the remaining
portion of the adhesive backing on the exposed portion
of the bulb. The pinched center section allows some
leverage for unscrewing of the bulb, and the tape
provide some insulation from the heat.

Extreme Voltage Shutdown Indicator: This LED is
normally off. It monitors a hazard unfortunately
common in the entertainment industry: wiring faults –
for example, accidental connection to 220VAC where
120VAC is expected. The PL-PROD, PL-PRODM, and
PM-PRODM sense voltages that are so high or low
that operation would be impossible and shuts the
power down before damage can occur. The cutoff
voltages are under 90V or over 140V. Upon initially
applying power to these units, the Extreme Voltage
indicator LED will be lit if the input voltage is above the
high cutoff, and power will not be applied to the unit’s
outlets. If the unit has been operating with an
acceptable input voltage and then that voltage goes
above 140V, it will shut off power to the outlet and the
Extreme Voltage LED will light.
NOTE: If the mains power is above the high cutoff
voltage and has caused the unit to remove power from
its outlets, it cannot restore power without the operator
manually turning the unit off, then on again. Avoid
turning the unit back on, without checking the source of
the problem first, and perhaps changing the AC source.
