AMPLICALL
TM
40 Use
The AMPLICALL
TM
40 has all the useful
features and works in the same way as the
AMPLICALL
TM
30. However it is supplied
with an additional accessory, an external
piezo buzzer. If you plug the piezo
buzzer into the AMPLICALL
TM
unit and
attach the other end near to the sound
source, it will disconnect the internal
microphone of the AMPLICALL
TM
40 and
can be used to detect doorbell sound.
