Pyramid Car Audio PSV-300 - Manual (Page 6)

OPERATION
To use the power supply after you connect the device to it, set POWER to turn it
on with the red led light illuminated.
If the power supply's POWER switch does not light, check all connections and
confirm the wall AC outlet has power.
If the outlet has power, set POWER to OFF, reduce the load (by using a device
that does not require more that 30 amps), then set POWER to ON. Your power
supply's overload protection circuit automatically shuts down the power supply
when it is overload and resets by turning POWER to OFF.
Caution: Place your power suppply in a well ventilated open and cool
area. Do not block the openings at the fan suction on the
sides and the discharge openings on the bottoms.
Cauton: To reduce the risk of energy hazard, be careful not to short
the output terminal during operation. Remove the output
connections after use.
Caution: Your power supply might cause TV or radio interference
even when it is operating properly. To determine whether
your power supply is causing the interference, turn off your
power supply. If the interference goes away, your power
supply is causing it.
Try to liminate the interference by:
• moving your power supply away from the receiver.
• connecting your power supply to an outlet that is on a different electrical circuit
from the receiver.
• contacting a qualified service technician for help.
