latch off without damage to the power supply. The power supply shall return to normal operation after the short circuit
has been removed and the power switch has been turned off for no more than 2 seconds.
In the event of an output short circuit condition on –12V output, the power supply will not be damaged. The power
supply shall return to normal operation as soon as the short circuit has been removed. and the power switch has
been turned off for no more than 2 seconds.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
◎
◎
◎
◎
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Modifications not expressly approved by the manufacturer could void the user's authority to operated the equipment
under FCC rules.
