Important Note
The lisa TV link is com-
patible with TV liste-
ning systems in the
Infra Light series or
comparable infrared TV listening
systems and popular loop amplifiers
(e.g. LA-215 ).
When using a Radio Light or com-
parable wireless TV listening
system operating on a frequency of
863 HMz, you will achieve the best
results by keeping a minimum
distance of 2 meters from the
lisa TV link. This is because the
signals from the wireless TV liste-
ning system and the lisa may inter-
fere with one another.
Operation
1. Signal sequence
Once a lisa radio signal is detected
by the lisa RF TV-Link, this device
converts the signal into the corres-
ponding sound and transmits it to
the TV hearing-aid system connec-
ted. The lisa RF TV-Link transmits
the sound for approx. 30 seconds,
during this time, the television volu-
me is turned down.
2. Transmission signal detection
The lisa RF TV-Link converts the sig-
nals sent by the lisa RF transmitter
into the different sounds (telephone
ringing, doorbell, baby cries, etc.).
At the same time, it is also possible
to see which lisa signal has been
sent because the corresponding LED
will either flash or light up for 40 se-
conds.

engine siren.
