if you carry your controller around with you and
move outside the operating range, transmission will
be interrupted and your hearing aids will switch to
the master program . the led will flash at slow in-
tervals to indicate that transmission has been inter-
rupted . the change will be indicated by a voice
message . if your hearing aids are set up with beep-
tone indication instead, no acoustic indication will
sound .
if you come in range again, the controller will detect
the signal from the tv/audio and restart transmis-
sion . a sound will be heard in the hearing aids . the
led will light constantly rather than flash .
note that the led may continue to be red if you
chose to turn off the hearing aid microphones dur-
ing transmission .
