Extract from Transceiver system diagram reference DTX-C7
If there is a fault condition that prevents the waveguide switch selecting a transceiver, the RDU will
make 10 attempts at reselecting the switch. After the 10
th
attempt the system reverts to the original
transceiver and the RDU will display an alarm stating Waveguide Switch Fail.
In this condition and providing the waveguide switch is not jammed is possible to manually change the
position of the waveguide switch using the rotary control on the top of the switch.
