Troubleshooting Guide
For most efficient troubleshooting, use high quality
headphones to monitor the quality of the signal
being fed into the T20. Plug them into the
“Tape Out/Phones” jack on the T20
Transmitter “Power” light not on.
1.
Make sure the wall transformer is plugged into
the transmitter correctly.
2.
Make sure the electrical outlet is on.
No sound through receivers.
1.
Try switching to the other channel on the R19.
2.
If some of the receivers work, but others don't,
check for bad batteries or earphones on the
receivers that aren't working. Check to see that
those receivers’ frequencies match the
transmitter frequency. The R19 is preset for
channels 33 and 53.
3.
If none of the receivers work, check to see if
the power is connected to the transmitter and
the “Power” light is on. Check to see if the
transmitter and receivers are set on the same
frequency. Look at the two channel switches
on the T20’s rear panel, checking the settings
against the chart on top of the T20. The
standard channels for the R19 are 33 and 53.
4.
Check to see if the Transmitter is connected
properly to the sound system. See page 8.
5.
Turn the screwdriver-adjust input level control
located on the T20 front panel clockwise to
increase the input signal strength until the
audio indicator light flashes.
6.
If you are not using an input signal from a
sound system, make sure the microphone is
plugged into the "Mic" jack on the rear of the
T20 transmitter and the input selector switch is
in the MIC (left) position.
7.
Make sure the antenna is installed and
connected properly. See pages 8 or 15.
Sound through receivers is excessively loud and
is distorted.
1.
The T20 transmitter is probably set to a wide-
band channel. Select a narrow-band channel.
Sound is of normal volume. “HI” audio light not
continuously on, but sound is distorted.
1.
The source audio might be distorted.
2.
Input select switch might be in wrong
position. Try other positions.
Too much noise when talking stops. Normal
sound compressed excessively. Red “HI” light lit
too frequently.
1.
Turn audio adjust counter-clockwise. Red
“HI” light should blink only occasionally.
Audio “OK” light should be on when there is
normal audio present.
2.
Consider changing the audio processor option.
The T20 is shipped in Compress Mode. See
page 11 for details.
Sound through the receivers is weak and noisy.
1.
Turn the screwdriver-adjust input level control
located on the T20 front panel clockwise to
increase the input signal strength until the
audio indicator light flashes. The audio fed
into the T20 may be noisy or weak. Use a
headphone in the Phones jack on the front of
the T20 to listen to the input signal. If it is
weak and noisy from the phones jack, turn up
the appropriate mixer control or try a different
audio source.
