:
Receiver Model PFM R31 has two volume control knobs (one for the FM signal, one for
environmental sounds), a microphone input jack, and an earphone output jack.
1. Make sure there are two charged AA batteries in the receiver. If batteries are not
installed, see Battery Information on page 10.
2. Insert the small Plug Mount Microphone (MIC 014) into the “Mic” jack on top of the
R31 Receiver. (See Figure 14.)
3. Plug the earphone or headphone into the “Ear” jack on top of the receiver.
4. Turn the power on by rotating the taller “FM” volume control on top of the receiver.
5. Place the earphone in your ear.
6. Choose the correct channel using the right switch on the R31’s back panel. If the
transmitter is on and tuned to channel 1, the FM Indicator light on the R31 will light.
7. Adjust the receiver tone control to your needs. (See Figure 13.)
Lo = more low frequencies; Mid = some low frequency cut; Hi = maximum low fre-
quency cut, emphasizes higher frequencies.
8. Place the receiver in the belt clip case provided. The receiver can be placed in a pants
pocket, or clipped onto a belt, harness, or waistband.
Adjusting The R31 Volume Controls
1. Adjust the taller “FM” volume control to a comfortable listening level. You should be
able to hear someone speaking into the transmitter microphone.
2. Now adjust the shorter “Mic” volume control until you can hear sounds picked up by
the environmental microphone on top of the receiver.
3. Adjust the two volume controls for a comfortable mix of FM and environmental
sounds. You will normally want to have the FM signal louder than the environmental
Mic signal to avoid picking up extra background noise. If no environmental sounds
are desired, turn the “Mic” control fully to “Min”. If you want to hear nearby conver-
sation or your own voice, turn the “Mic” control up.
