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.
