(7) Turn “on” the receiver by actuating the front-panel “POWER” switch. The
power-on LED should illuminate.

(8) Install a battery in the transmitter, turn it “on,” and position it in the
approximate center of the area to be covered by the wireless system.

(9) Set the “FRONT PANEL LEDs” switch (located on rear panel) to the “ON”
position. Both squelch (“SQ”) indicators on the receiver should be illuminated.

(10) Set the front-panel “RF METER SELECT” switch to “A” and observe the
“RF SIGNAL LEVEL” bargraph. If the bargraph does not read above “8,” one or
more problems are indicated (e.g., defective transmitter, receiver, or antenna,
excessive distance between transmitter and receiver, or severe RF propagation
problems). Refer to section “In Case of Difficulty.”

(11) Turn the “RF METER SELECT” switch to “B” and again observe the
bargraph. The reading should be approximately the same as for the other channel.
Next, set the “RF METER SELECT” switch to “DIV” and the “DIVERSITY
SELECT” switch to “NORM” (diversity). The RF meter should read
approximately the same as for the higher of the two channels, and the diversity
indicators should show selection of that channel.

(12) Turn on the transmitter to be used with the system. If using a bodypack
transmitter, connect the microphone to the transmitter.

(13) The audio levels should now be set for the system. With the microphone
positioned normally, speak loudly into it. Adjust the audio gain control on the
transmitter so that the “AUDIO LEVEL” meter on the receiver reads
approximately “0.”

(15) The receiver audio-output level should now be adjusted by means of the
recessed “AUDIO OUTPUT” control on the front panel. Verify that the receiver
output is not overloading the input of the mixer or amplifier it is feeding.

(16) “Walk” the coverage area to ensure that there are no areas of poor coverage.
Signal “dropouts” (little or no signal in small areas) show up as a large drop in
the level shown on the “RF SIGNAL LEVEL” indicator or a flickering of the
“SQ” indicators on the receiver. The audio may be conveniently monitored with
headphones plugged into the front-panel “MONITOR” jack on the receiver. If
there is an area where a “dropout” occurs (very unlikely with a diversity
receiver), the receiving antennas can usually be repositioned to eliminate the
problem. Frequently, a change of just a few inches in location will completely
solve the problem.
