Troubleshooting; Power Indicator Is Not Lit; Fuse Replacement; No Sound - Rotel RA-10 Manuel De L'utilisateur

English
If this happens, turn the amplifier off. Let it cool down for several minutes,
and attempt to identify and correct the problem that caused the protection
circuitry to engage. When you turn the amplifier back on, the protection
circuit will automatically reset and the indicator LED should go out.
In most cases, the protection circuitry activates because of a fault condition
such as shorted speaker wires, or inadequate ventilation leading to an
overheating condition. In very rare cases, highly reactive or extremely low
impedance speaker loads could cause the protection circuit to engage.
If the protection circuitry triggers repeatedly and you are unable to isolate
and correct the faulty condition, contact your authorized Rotel dealer for
assistance in troubleshooting.

Troubleshooting

Most difficulties in audio systems are the result of incorrect connections,
or improper control settings. If you encounter problems, isolate the area
of the difficulty, check the control settings, determine the cause of the fault
and make the necessary changes. If you are unable to get sound from
the RA-10, refer to the suggestions for the following conditions:

Power Indicator Is Not Lit

The Power Indicator and the basic items in the Display window should
be lit whenever the RA-10 is plugged into the wall power outlet and the
Power button is pushed in. If it does not light, test the power outlet with
another electrical device, such as a lamp. Be sure the power outlet being
used is not controlled by a switch that has been turned off.

Fuse Replacement

If another electrical device works when plugged into the power outlet,
but the Power Indicator of the RA-10 does not light when plugged into
the same outlet and the Power Switch is pushed in, it indicates that the
internal power fuse may have blown. If you believe this has happened,
contact your authorized Rotel dealer to get the fuse replaced.

NO SOUND

Check the signal source to see if it is functioning properly. Make sure the
cables from the signal source to the RA-10 inputs are connected properly.
Be sure the Listening Selector is set to the proper input. Check the wiring
between the RA-10 and the speakers.
