The Service - Gamut M250i User Manual

Changing the fuse more than once can increase the repair price, and you can cause a re or a deadly
electrical shock.
These sand- lled types can break up to 1000 Ampere current, a normal slow blow fuse can only
break 35 Ampere, so it may not stop the current!
If the ampli er still is silent, but the blue power lights are on, you can check it in the following way:
Switch o power and wait 15 seconds and then switch it on and listen carefully. There should be
a quiet mechanical click coming from the inside of the ampli er.
If not, disconnect the input cables and try again. Now listen closely to the loudspeaker.
A small click should come from the loudspeaker, just after the click from inside the ampli er.
If not, check the loudspeaker cables.
If you hear clicks in the loudspeakers, and still do not get sound, the ampli er is probably OK..
Try exchanging the input cables with another cable. and check that it transmits a signal, by connecting
it to antoher ampli er.
If you only get the mechanical click (it comes from the relay closing inside) and you have checked
the loudspeaker cables and the loudspeaker, then you should call your dealer.
If you hear a small click every second from the loudspeaker, then you have a bad input signal,
or a short circuit on the output, which causes the protection circuit to take action.
Check that the input cable screen is OK and that all plugs are tightly and correctlt connected.
Check the loudspeaker cables. In case you cannot solve the fault by doing the above, call your
dealer.
