the base. If you have more than one base, you can
change between these by placing the controller in
the base you wish to use for approx. 5 seconds.

We recommend that you hang the controller around
your neck when in use, on the lanyard provided.

The breakaway buckle of the lanyard must be posi-
tioned at the back of your neck (1).
TRANSMISSION
With either TV or audio connected
• Press the transmission on/off key on the control-
ler once to start transmitting from the connected
source. An acoustic signal will sound in your hear-
ing 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
indicated 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 control-
ler once to start transmission from the TV. An
acoustic signal will sound in your hearing aids,
and the transmission 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
indicated by a voice message or beep tones. The
green LED will change briefly to red and then off.

UP
DOWN
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.
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.
