Notes:
The earphone cord is the receiving antenna. Do not bunch up the cord or wrap it around the receiver. For best reception, the cord should hang as straight as possible. Make sure the Receiver is turned OFF when not in use. The channel selector can be used to switch between an individual and a group channel.
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 environ- mental 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 conversation or your own voice, turn the “Mic” control up.
