Receiver Management Suggestions
Dierent types of facilities will use dierent approaches for receiver management
and earphone sanitation. Below are some options that customers have used
successfully.
• Regular users purchase their own receiver and take care of their own batteries
and earphone.
• Some facilities label the receiver and earphone with the names of regular users
so each person uses the same receiver and earphone.
• The receivers can be stored in a multiple compartment storage case with a
credit card or driver’s license left as collateral for the receiver.
• Regular users purchase their own earphone or headphone and bring them to
use with receivers at the facility.
Operating the Receiver
Turn the receiver on by rotating the volume control knob. The ON indicator should
illuminate RED. Choose from 8 standard channels. Turn the channel selector knob to
the desired channel.
IMPORTANT: Make sure the receiver channel matches the transmitter frequency!
Adjust the volume to a comfortable listening level. To turn the receiver o, rotate
the volume control knob to the left until it clicks o. The ON indicator should not be
lit. To prolong the battery life of the unit, turn the receiver o when it is not in use.
Troubleshooting Guide
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.
• If none of the receivers work, check to see if the power is connected to the transmit-
ter and the frequency display on the front of the transmitter is illuminated.
• 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
ashing occasionally but not continuously.
• 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 with line of site to
transmitter antenna.
• Check to make sure no other transmitters (or other devices) are transmitting on the
same frequency (channel).
Sound through receivers is loud, but distorted. Noise (room noise or electronic
noise) seems to grow after talking stops. Audio Indicator Lights up continuously.
• Turn the screwdriver-adjust audio level control on the front of the T27 transmitter
counter-clockwise to decrease the audio level. The audio indicator light should ash
occasionally, but not be lit continuously.
Sound through the receivers is weak and noisy.
• Turn the screwdriver-adjust audio level control located on the T27 front panel
clockwise to increase the input signal strength. The audio indicator light should
ash occasionally.
• Increase the input signal level from the sound system.
Buzzing or humming noise in sound system.
• There is nothing wrong with the T27 Transmitter. One or more pieces of equipment
in the sound system are being disturbed by RF (Radio Frequency) signals produced
by the T27. The most likely suspects are other equipment primarily through the
power cord, speaker wires, or unshielded inputs, all of which can act as antennas
• Move the Transmitter away from the other sound equipment.
• The most likely suspects are other equipment primarily through the power cord,
speaker wires, or unshielded inputs, all of which can act as antennas. Try the
following steps:
1. Move the Transmitter away from the other sound equipment.
2. Make sensitive equipment more immune to RFI/EMI.
