out partsthat couldresult infire or electricshock. Neverspill orspray anytype of liquidon theproduct.
If an outside antenna is connected to the product, be sure the antenna system is grounded so as to provide some
protection against voltage surges and built-up static charges. Section 810 of the NationalElectric Code, ANSI/NFPA
70, provides information with respect to proper grounding of the mast and supporting structure, grounding of the
lead-in wire to an antenna discharge product, size of grounding conductors, location of antenna discharge product,
connection togrounding electrodes,and requirementsfor grounding electrodes.
Do not attempt toservice this product yourself asopening or removing covers mayexpose you to dangerousvoltage
or otherhazards. Referall servicingto qualified servicepersonnel.
When replacement parts are required, be sure the service technician uses replacement parts specified by the
