Nº512 CD/SACD™ Player
Disc Loads but Won’t
Play
1. Verify that the disc uses formatting that is supported by the
Nº512 CD/SACD player. Refer to the list of compatible disc
formats found earlier in the manual.
2. Verify that the disc is not scratched or otherwise damaged.
3. Verify that the disc is not dusty, soiled, or marked with
fingerprints.
4. Reload the disc, making sure that the disc is firmly seated in the
tray and the label is facing up.
5. Verify that the loaded disc is NOT blank.
Audio Has a Humming
Sound
1. If a cable TV connection is present, disconnect the cable from
the wall outlet. If this eliminates the humming sound, a ground
loop isolation device is required. Contact your dealer or cable
provider for assistance.
2. Disconnect the components one at a time to isolate the
problem. Once the problem is identified, make sure the
associated component is properly grounded and connected to
the same electrical circuit as the Nº512.
Remote Control
Doesn’t Work
1. Eliminate obstructions between the remote control IR
transmitter and the front panel display IR receiver/transmitter.
The remote control must be in line-of-sight with the front panel
IR receiver for proper operation.
2. Replace the remote control batteries. Verify that the remote
control batteries are inserted correctly with the proper polarity.
3. Make sure the IR input connector is not being used.
4. Make sure the front panel display IR receiver/transmitter is not
exposed to strong sunlight, halogen light, or fluorescent light.
This can cause IR reception to become unreliable. If the Nº512 is
placed inside a glass cabinet, tinted glass will reduce the remote
control range.
5. If you have multiple Mark Levinson products, verify that you
are using the proper remote control for the product in question.
RF Interference
1. Verify that the Nº512 is not positioned too close to RF-emitting
devices. Move such items one at a time to isolate which device is
causing the problem.
2. Replace unshielded cables with shielded cables wherever
possible.
