Notes
• For the connection from the WD-820A to the WRR-850A/840A/820A,
refer to the operating instructions for the WD-820A or the WRR-850A/
840A/820A.
• The 9V power for the booster amplifiers of the AN-820A UHF antenna
is supplied from the ANTENNA a and b ANT IN/DC OUT (9V/OFF/
12V) connector of this unit. Be sure not to short-circuit these
connectors. If short-circuited, the protection circuit activates and the
power supply stops. To resume power supply, first eliminate the short
circuit, then set the DC OUT switches to OFF and return them to the
original position after 2 or 3 seconds.
• Always use a pair of antennas a and b, as shown above.
For installation and the reception ranges of the antennas, refer to the operating
instructions for the WRR-850A/840A/820A UHF synthesized diversity tuners.
