up?
− Has the receiver been set to the trans-
mission channel of the transmitter (chap-
ter 4.3)?
− Is the mode shown on the receiver the
same as the mode shown in the rectangle
(e) on the right side of the display of the
transmitter? Switch the receiver off and
on again.
Talking via the receiver not possible
− In the mode "Guiding", the selector
switch "s / m" (5) of the transmitter must
be in the position "s".

− In the mode "Teaching", a member can
only talk when the assistant has switched
off his / her microphone by means of the
talk button.
− In the mode "Discussing", it is generally
not possible to talk via a receiver.
