Selecting a frequency for the R31, R32, R-35 and R7-4 receivers requires an adjustment to the internal
tuning coil(s). See Figure 18 for receiver types to locate the coils to be adjusted. A plastic tuning
wrench (PLT 005) will be needed to adjust these receiver tuning coils.
Most Williams Sound single channel Receivers are set at the factory to 72.9 MHz. The standard
four-channel receivers (R7-4), channels 1-4, are usually set to frequencies 72.1, 72.5, 72.9, 75.7 MHz
respectively.
The Receiver must be tuned with a weak and somewhat noisy signal. If tuned too close to the
transmitter, with a strong signal, the most accurate tuning of the receiver is not possible.
To Change the Frequency to Another Channel:
