Recognizing Wireless Signals
The M812 speaker and transmitter base are manufactured to
automatically recognize each other wirelessly during operation through
a process called "RF mating." However, there are occasions when signal
jamming can interfere with this process; for example, when a second
M812 system is operating within a 100 foot range. If this occurs, try
changing the RF channel.
