Troubleshooting Guide
Read through the manual and user guide carefully to verify proper
setup and installation of your system.
Transmitter frequency display (LED) not lit.
•
Make sure the wall transformer is plugged into the transmitter.
•
Make sure the electrical outlet is on.
No sound through receivers.
•
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 the receiver frequency matches the transmitter frequency.
On the transmitter, the frequency is illuminated on the LED panel on the
front of the unit. On the receiver there may be a sticker on the inside of the
battery door of the receiver. If these frequencies do not match, see Select
the Frequency Instructions on page 6 (transmitter) and page 11 for the R37,
page 13 for the R37-8 or page 16 for the PPA R38.
•
If none of the receivers work, check to see if the power is connected to
the transmitter and the frequency display on the front of the transmitter is
illuminated.
•
Check to see if the transmitter is connected properly to the sound system.
See page 6 - 7.
•
Turn the screwdriver-adjust audio input level control on the front panel of
the T27 transmitter clockwise to increase the audio level. Make sure that
the audio light is flashing occasionally but not continuously.
•
If you are not using an input signal from a sound system, make sure the
Williams Sound microphone is plugged into the “Mic” jack on the front of
the T27 transmitter.
•
Make sure the antenna is installed and connected properly. See page 5.
Insufficient range, good reception near transmitter, poor at a distance
•
Check to see if the antenna was installed correctly. If not, correct or
replace the antenna. The signal should be clearly audible at least 100 ft
with line of site to transmitter antenna.
•
Check to make sure no other transmitters (or other devices) are
transmitting on the same frequency (channel).
