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
RC-1570, refer to the suggestions for the following conditions:
Power Indicator Is Not Illuminated
The Power Indicator ring around the power button and the basic items in the
Display window should be illuminated whenever the RC-1570 is plugged
into the wall power outlet and the POWER switch 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 still will not light when the RC-1570 is plugged into
the wall outlet, 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 RC-1570 inputs are connected properly.
Check all the wiring between the RC-1570 and the power amplifier, and
the speakers.
Cannot Connect via Bluetooth
If you cannot pair your Bluetooth enabled device to the RC-1570, delete the
memory of the previous connection on the RC-1570 and on your device. On
your device this is often listed as "Forget this Device". On the RC-1570 IR
remote PRESS and HOLD the STOP
display shown "Reset BT DB List?" then release the button. Select <Yes>
and press "ENT". Then try to make the connection again.
