21. Wall or Ceiling Mounting – The appliance should be mounted to a wall or ceiling only as
recommended by the manufacturer.
22. Power Lines – An outdoor antenna should be located away from power lines.
23. Outdoor Antenna Grounding – If an outside antenna is connected to the receiver, be sure the
antenna system is grounded to provide some protection against voltage surges and built up static
charges. Section 810 of the National Electric Code, ANSI/NFPA No. 70-1984, provides information
with respect to proper grounding of the mats and supporting structure grounding of the lead-in
wire to an antenna-discharge unit, size of grounding connectors, location of antenna discharge unit,
connection to grounding electrodes and requirements for the grounding electrode. See Figure below.
EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE Note to the
CATV system installer: This reminder is provided to call the CATV system installer's attention to
Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies
that the cable ground shall be connected to the grounding system of the building, as close to the
point of cable entry as practical. Please, make sure to connect the power plug to the wall outlet
socket after connecting the MFM to the adapter!
24. Apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as
vases, shall be placed on the apparatus.
25. Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the
equalizer to maximum increases the earphones and headphones output voltage and therefore the
sound pressure level.
CAUTION
These servicing instructions are for use by qualified service personnel only. To reduce the risks of electric
