Trouble shooting
No reception or disturbed reception
The operation indicator doesn’t light up – the Quadpack is not powered:
̈ Check if the mains unit is connected to the mains and if the POWER
(ON/OFF) switch is set to position “I”.
̈ Plug the mains connector to a wall socket, connect the mains unit to the
Quadpack and set the POWER (ON/OFF) switch to position “I”. The
operation indicator lights up red.
The Quadpack’s power supply has already been checked, but the operation
indicator still doesn’t light up – the fuse of the Quadpack has been triggered:
̈ Check every unused receiver slot for objects that might have triggered
the fuse and remove these objects.
̈ Check the DC polarity of the power supply. The correct polarity is
shown in the diagram next to the socket!
̈ Set the POWER (ON/OFF) switch to position “0”.
̈ Unscrew and remove the fuse holder ¾.
̈ Remove the defective fuse.
̈ Insert a new fuse with the same rating (1 AT).
̈ Replace the fuse holder ¾ and screw it tight.
̈ Set the POWER (ON/OFF) switch to position “I”.
The operation indicator ´ lights up red.
The receiver display remains dark – the receiver has not been turned on:
̈ Press the ON button on the receiver. The receiver display indicates the
selected frequency or the channel number.
Selective input modules are used but the selected transmission and receiving
frequencies are not within the frequency window of the selective input
modules:
̈ Set all transmitters and receivers operated with the Quadpack to
frequencies that are within the frequency window of the selective input
module.
The frequency window of the selective input modules is printed onto the
modules.
The antennas are not connected correctly:
̈ Check all antenna connections. If two daisy-chained Quadpacks are
operated with only one pair of antennas, please check the antenna
cabling (see „Daisy-chaining two Quadpacks” on page 26).
