External microphone
You can connect an external microphone to the Transmitter’s 2.5 mm socket
(20). The Battery Status LED blinks orange several times to conrm that an ex-
ternal sound source has been connected. The External Sound LED (4) will light
up green and orange at the same time to indicate that the sound is coming
from an external sound source.
In some cases it may, for example, be easier for a lecturer to have an external
microphone and a Transmitter Unit in his/her pocket than to speak in a loud
voice or carry a wired microphone.
A Transmitter Unit can transmit speech to one or more Receiver Units at the
same time.
The input sensitivity is automatically adjusted to a suitable amplication when
an external microphone is connected.
Please note that the Transmitter Unit’s Battery Status LED (17) blinks alter-
nately green and orange several times when an external sound source is
connected.
