• 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, adjust them as needed.
• 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.
• On the front panel of the T27 transmitter, turn the audio input level
control clockwise using a screwdriver 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 AV microphone is plugged into the Mic jack on the front of the
T27 transmitter.
• Make sure the antenna is installed and connected properly.
Insucient 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.
within the line-of-site to the transmitter antenna.
• Check to make sure no other transmitters (or other devices) are
transmitting on the same frequency or channel.
