Operating the PPA R37 Receiver
1. Insert two (2) AA batteries ensuring correct polarity. If rechargeable NiMH batteries are to be used with the receiver and a
Williams Sound charger, make sure the Alkaline/NiMH switch inside the battery compartment is set to NiMH before charging.
See Figure 25.
2. Insert the headphone, earphone or neckloop into the headphone jack.
3. Turn receiver on by turning up the volume control. The green power LED will turn on.
4. Press the Channel Seek button inside the battery compartment once to seek an active transmitter. See Figure 25. If more than
one transmitter is being used, push the seek button additional times until you locate the signal you want to hear. The receiver
will retain the channel setting when the unit is turned off.
5. To lock or unlock a selected channel, turn the power off. While holding the seek button, turn the power back on. When locked,
the receiver will remain on the current channel regardless of channel seek button presses.
6. For more information about the R37 receiver, refer to the PPA R37 User Manual. You can download any of the receiver
manuals from our website at www.williamssound.com.
