Gently put the tip of the tuning tool 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.

8:
Turn the tuning slug in a counter-clockwise 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 audio source being heard.

PPA R19
The R19 is a two-channel narrowband receiver operating on 72.900 and 75.700 MHz frequencies. It
features volume control on/off switch, channel selection switch, earphone jack, tone control selection
switch and on/off power indicator.
NOTE: The R19 and R19-6 narrowband receivers use crystals to designate frequency selection and are
therefore not field tunable. To select a different operating frequency, the receiver must be returned to
Williams Sound for service.
