If your Personal FM System is not working, check the following: 

1.  Make sure the batteries are fresh or completely charged and that the “plus” and “minus” 

terminals are installed correctly. 

2.  If the rechargeable batteries will only work for a short period of time (less than 1 hour) 

even after they are fully charged, they must be regenerated. Leave them in the receiver or 
transmitter with the unit turned on, for 5 - 6 hours. Then turn receiver or transmitter off, 
place it in the charger, and charge for 14 - 16 hours. This should restore normal battery 
life. Rechargeable batteries will gradually lose their capacity over time and should be 
replaced every year. 

3.  Make sure the microphone is plugged into the T30 Transmitter and the earphone is 

plugged into the Receiver. 

4.  If you have the PFM System 350, make sure the R31 Receiver’s plug mount microphone 

IS NOT plugged into the Transmitter. 

5.  If you’re using the PFM System 350 with the PFM R31 Receiver, make sure that the 

earphone has been plugged into the earphone jack and not into the R31 Receiver’s 
microphone jack. 

6.  Move the Transmitter and Receiver closer together. You may be out of range. When 

using the system indoors, it’s normal for the signal to momentarily disappear in certain 
locations. This is called a “drop-out.” Moving a few feet will restore the signal. 

7.  Make sure that the Transmitter and Receivers are tuned to the same channel. The units 

have stickers inside the back cover identifying the channel. Unless the Transmitter 
channel has been changed, set the Receiver to channel 1. 

8.  Do not try to use more than one Transmitter on the same channel in close proximity to 

each other. MORE THAN ONE TRANSMITTER ON THE SAME CHANNEL WILL 
RESULT  IN INTERFERENCE IF THEY ARE CLOSE TOGETHER. Keep the systems 
50 - 100 feet apart or use separate channels for each system used. 

9.  If you are still hearing interference on the Receivers, turn the Transmitter off and listen 

with a receiver. If you hear the interference with the Transmitter off, you need to change 
to a clear channel. See the re-tuning instructions. 

10.  If problems remain, contact your dealer for further help. Or call Williams Sound toll-free 

at 1-800-843-3544.
