Step 6: Adjust the audio Level
Locate the “Gain Control” on the rear of the T800. With the audio
source playing, rotate the “Gain Control” clockwise “+” to increase or
counterclockwise “-” to decrease gain. Monitor the audio indicator “bars”
on the display as you make your adjustments. As a general guideline:
No audio indicator bars present = Audio source is TOO LOW.
Some audio indicator bars present = Audio source is ACCEPTABLE
“Limiting” message is displayed = Audio source is TOO HIGH.
Ensure the audience is receiving the highest quality audio: listen
to the audio through the headphone jack on the front of the
T800 (FIG. 2).
Step 7: Listen with an FM Receiver
IMPORTANT: The FM receiver being used with the T800
transmitter will need to be on the same frequency as the
transmitter!
Install the receiver batteries, plug in the earphone, turn on the receiver
and walk around the listening area. The signal should be clear and quite
loud when the volume is turned up. See page 9 for detailed operating
instructions on the R863 receiver.
