NSTALLATION
Open the battery compartment using a coin in the slot in the bottom of the receiver. Press the
batteries into place,
observing proper battery
polarity. Incorrect insertion of the batteries is
difficult, and may cause both mechanical and electrical damage to the receiver not covered by
the 5 year warranty. The receiver will not work with the batteries incorrectly installed.

ONNECTING
E
ARPHONES
Plug an earphone into the jack near the thumb wheel volume control. Only monophonic
earphones will operate properly. If stereo headphones are used, sound will be heard only in
one side. A suitable adapter (Radio Shack Part #274-368), can be used so that stereo
earphones operate on both sides. Williams Sound extensively evaluates the earphones and
headphones included with the PPA 275. We can only assure optimum performance when
Williams Sound earphones and headphones are used.

PERATING THE
R
ECEIVER
Turn the receiver on by rotating the volume control in the direction of the arrow on top of the
case. The “On” indicator will light.
Turning the knob in the direction of the arrow will increase the volume. Turning the knob
against the arrow will decrease the volume. To avoid depleting the batteries, make sure the
receiver is turned off when not in use.
If you’re using the PPA 275 with an existing sound system, make sure the sound system is
turned on. Have someone speak into a sound system microphone while you listen with the
receiver and earphone. You should be able to hear their voice through the receiver.
If you’re using the PPA 275 with a microphone—and not a complete sound system—have
someone speak into the microphone while you listen with the receiver and earphone. You
should be able to hear their voice through the receiver.
Note:
The earphone cord is the receiving antenna. Do not bunch up the cord or wrap it
around the receiver, while in use.
