Operating Intructions:
Step 1
Plug the earphone into the earphone jack. The earphone cable also acts as the receiver antenna. Extend the cable fully for the best reception and least interference.
Step 2

Correcting Interference
With any type of radio-frequency (RF) device, other RF sources can interfere with reception. Even the Assistive Listening Band is occasion­ally subject to use by other types of devices.
To check for on-channel interference, take the Digital-1 receiver to the place where the interfer­ence is the worst and turn off the transmitter. The interfering signal should now become stronger. Set the TX-37A transmitter and the receivers to a different channel and return to the same place. If interference continues, try changing channels again until you get a clear signal.
If more than one TX-37A is operating in the same area, try to keep the channels used as far apart as possible (3 channel spacing recommended).
