Interference can be determined by turning the equipment off and on.
If this equipment does cause harmful interference to, or suffer from harmful interference of, surrounding
equipment, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna or equipment.
• 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 technician for help.

the MDSC-8255 requires
continued operation
during power mains
interruptions, it is
recommended that the
MDSC-8255 be powered
from an uninterruptible
power supply or a battery.
