Trouble shooting

Cause 1:
Mains lead not plugged in correctly.
Remedy:
Check connection, push connector in firmly.
Cause 2:
Mains switch on the back panel not switched on.
Remedy:
Switch the mains switch on.
Cause:
The antenna lead is routed too close to a mains, remote control or audio signal
cable.
Remedy:
Move the leads so that they are spaced well apart. Use the domestic (loft or
outside) antenna or a cable connection.
Cause 1:
The station is not broadcasting RDS information.
Cause 2:
Reception is poor, interference is severe, or the field strength (signal strength)
is low.
Remedy:
Select only those stations which can be received with a strong signal: hiss-free
and without interference.
Cause:
The antenna system or antenna cable is faulty.
Remedy:
Check the antenna lead for good contact at the antenna socket (at the wall)
and in the back of the tuner. As a test, try using the system with a trailing
antenna. If you can now receive stations reasonably well, we recommend that
you call out an expert antenna technician to check your antenna system.
