RECEIVER FREQUENCY CHANGE INSTRUCTIONS

Tuning for the R7, R30, R31, and R32 receivers is determined by a single tuning coil. In the R7-4

and R7-6, one coil is assigned to each switch position. See the following 6 figures and 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 (R7-4NA), Channels 1-4, are usually set to frequencies 72.1, 72.5, 72.9, 75.7

MHz respectively. The standard six-channel receivers (R7-6N), channels 1-6, are set to frequencies

72.1, 72.5, 72.9, 75.7, 74.7 and 75.3 MHz respectively.

The Receiver must be tuned with a weak and somewhat noisy signal. If tuned too close to the trans-

mitter

with a str

ong signal,

the most accur

ate tuning of the receiver is not possible.

To Change the Frequency to Another Channel:

Step 1: Set the transmitter to the channel desired and remove the antenna.

Ste

p 2:

Connect an audio sour

ce to the tr

ansmitter such as a CD or cassette

pla

yer or microphone.

Ste

p 3:

Move the receiver about 25 feet away from the transmitter to set the

tuning

Step 4: Open the battery compartment, then lift up on the battery door to open

the back of the receiver. This will expose the tuning coil or coils to be

adjusted.
