PPA R35 RECEIVER FREQUENCY CHANGE INSTRUCTIONS

Selecting a frequency for the R35 receiver requires an adjustment to the internal tuning coil. See figure below to locate the coil to be adjusted. A plastic tuning wrench (PLT 005) will be needed to adjust this receiver’s tuning coil.

Most Williams Sound single channel Receivers are set at the factory to 72.9 MHz.

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:

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

STEP 2: Connect an audio source to the transmitter such as a CD or cassette player or microphone.

STEP 3: Move the receiver about 25 feet away from the transmitter to set the tuning.

STEP 4: Open the battery compartment on the back of the receiver.

STEP 5: Locate the Tuning Coil (see figure above). The tuning coil is a small. shiny

metal can with a screwdriver slot in a tuning slug in the top center. The Tuning Slug is usually black or gray.

STEP 6: With the earphone or headphone supplied with the receiver plugged into the Ear Jack, turn the volume control to a comfortable level, and listen for the transmitted signal.

STEP 7: Gently put the tip of the tuning wrench into the slot in the tuning slug. Be careful not to push hard on the slug so as not to damage the threads in the coil, and do not screw it down more than 3 turns into the coil.

STEP 8: Turn the tuning slug in a counterclockwise direction about two turns. Then, slowly turn the tuning slug in the clockwise direction until the signal is heard. There may be two signal points heard. The one which is received first is a false response. Be sure to continue tuning slightly further to the correct point, which will be much louder. Tune back and forth to find the center of the point of best response to the program being heard.

STEP 9: Mark down the date, and if a new frequency has been chosen, mark it down inside the receiver case for future reference.
