Selecting a frequency for the R35 receiver requires an adjustment to the internal tuning coil
(FIG 6.). Use a
plastic
tuning wrench (PLT 005) to adjust the tuning coil.
Most R35 single channel Receivers are set at the factory to 75.7 MHz (when delivered with
tour guide system).
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.

:
Step 1: Set the transmitter to the channel desired.
Step 2: Connect an audio source to the transmitter such as a CD, MP3, player or use the mic.
Step 3: Move the receiver about 25 feet away from the transmitter to set the tuning.
Step 4: Open the battery compartment.
Step 5: Locate the Tuning Coil (see FIG. 6). Each tuning coil is a small, square, 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 an earphone or headphone plugged into the “Headphone/Earphone” 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.
