TRANSMISSION
With either TV or audio connected
• Press the transmission on/off key on the controller
once to start transmitting from the connected
source. An acoustic signal will sound in your hearing
aids, and the transmission LED will turn green.
• Press the key again once to stop transmission. The
hearing aids will enter the Master program as indi-
cated by a voice message or beep tones. The green
LED will change briefly to red and then off.
With both TV and audio connected:
• Press the transmission on/off key on the controller
once to start transmission from the TV. An acoustic
signal will sound in your hearing aids, and the trans-
mission LED will turn green.
• Press the key a second time to transmit sound from
the audio source instead. An acoustic signal will
sound in your hearing aids.
• Press the key a third time to stop transmission. The
hearing aids will enter the Master program, as indi-
cated by a voice message or beep tones. The green
LED will change briefly to red and then off.
18

If you carry your controller around with you and move
outside the operating range, transmission will be in-
terrupted and your hearing aids will switch to the Mas-
ter program. The LED will flash at slow intervals to in-
dicate that transmission has been interrupted. The
change will be indicated by a voice message. If your
hearing aids are set up with beep-tone indication in-
stead, no acoustic indication will sound.
If you come in range again, the controller will detect
the signal from the TV/Audio and restart transmission.
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 during trans-
mission.

Adjusting the volume
Press the volume up key to raise the volume of the
transmitted TV or audio sound. Press the volume
down key to lower the volume.
Mute
You can mute the transmitted TV or audio sound on
the TV or audio source.
Room off
If you wish to turn the hearing aid mi-
crophones off during transmission, so
that you only hear the transmitted
sound, press the room on/off key once.
To turn the microphones back on, press again. An
acoustic indicator will sound in your hearing aids, and
the red LED will turn off.
