CAUTIONS AND WARNINGS
CAUTION: Do not stand in front of waveguide during operation. Especially, do not look into the
waveguide.
CAUTION: Do not allow any items to fall into the unit from the waveguide opening.
WARNING: DO NOT ALLOW EQUIPMENT TO BE IN STANDING WATER. While the BUC/SSPA is
designed to be used outdoors, the equipment is not designed to operate in standing water. Failure to
follow this precaution could result in electric shock and injury to persons.
WARNING:Power to the unit must be shut off before the DC cable is disconnected and the DC cable and
M&C cable must be disconnected before servicing.
CAUTION:Apply voltage to the DC input connector only as specified in the original configuration of this
unit. Application of a voltage outside of the specified range may cause the unit to become damaged or
non-functional.
CAUTION:Electrostatic Discharge (ESD) can damage electronic circuits. The M&C and RF input
connector center pins may be sensitive to ESD. Follow proper ESD precautions when handling these
products.
