Switching off
The hearing amplifier switches itself
off automatically about 60 seconds
after you put the handset back on the
hook. The green light goes off again.
Possible connections
The TA-2 is equipped with a 3.5 mm
stereo jack socket to which the follo-
wing accessories can be connected:
• Mini-headphones, e.g. Walkman
headphones
• Hearing aid wearers can connect a
neckloop to the jack socket.
The hearing aid must be set to »T«
or »MT« in this case. It is easy to
set the volume using the volume
control on the TA-2 .
• Hearing aids with a direct audio
input allow a direct link to be esta-
blished between the telephone and
the hearing aid. Both a monaural
cable (for wearers of a hearing aid
in one ear) and a binaural cable
(for wearers of hearing aids in both
ears) are available for this.
Please note that the loudspeaker in
the telephone handset is switched off
when a unit is connected to the jack
socket (to avoid feedback).
