What to do, if...
In this chapter we want to give you a few hints, which will help to resolve smaller
problems.
6.1 ... nothing works?
Is the power supply plug inserted correctly? - Put the power supply plugs firmly into the
plug socket.
Does the mains voltage rest against the used main plug socket, or has the home fuse
maybe reacted? – Examine the home fuse.
Did the internal micro fuse burn through? – Return the device back for service.
6.2
... one hears nothing?
Is the correct entrance at the amplifier selected? - Select the correct entrance.
Does the
Exxceed
supply at all a signal? – Attach the
Exxceed
to another entrance
and examine if it functions. If this is the case, something is wrong with the other entrance
of the amplifier. - Examine the entrance of the preamplifier.
Was a computer data CD inadvertently inserted? – Insert an audio CD.
6.3
... it hums?
Are the connecting cables tight and firmly put in? – Examine connection leads.
Sometimes multiple groundings can cause so-called humming loops. This problem
requires an experienced technician. We recommend you to contact your specialist dealer.
... It hums only, if the tuner, the video recorder, or the television is connected to the
preamplifier. - All these devices are connected with a grounded antenna. Thus it causes a
humming loop again, which can be simply eliminated, in this case simply with a fan-jet
filter, which is switched into the antenna inlet. Such fan-jet filters are available
inexpensively in radio and television speciality shops.
