Troubleshooting

Other than occasional replacement of the batteries in the remote control units, the DC-1 requires minimal maintenance. Use a soft, lint-free cloth slightly dampened with warm water and a mild detergent to clean the exterior surfaces of the unit.

Do not use alcohol, benzene or acetone-based cleaners

or any strong commercial cleaners.

Avoid using any abrasive materials such as steel wool or metal polish. If the unit is exposed to a dusty environment, a vacuum or low-pressureblower may be used to remove dust from the DC-1 exterior.

If severe power surges or sags cause problems with DC-1 memory storage, or you simply want to start with a clean slate, you can restore all of the factory defults with the following procedure.

This will erase any programs you have stored,

as well as all setup and calibration values.

Note any settings you want to re-use before proceeding.

Turn the DC-1 OFF with either the front panel switch or the remote. Turn the unit back ON and immediately press and hold BYPASS on the remote. (Make sure you do not block the infrared receiver on the DC-1 front panel.) The on-screen display will read:

FACTORY PRESETS MENU

EXIT

RESTORE DEFAULTS

If you want to resume normal operation without restoring all defaults, this is your last chance. Use MENU or to highlight EXIT, then press

SELECT.

To restore defaults, use MENU or to highlight RESTORE DEFAULTS, then press SELECT. This will clear and reload all preset effects and all factory settings of Volume, Balance, Contrast, Configuration, etc.

When the message FACTORY DEFAULTS RESTORED is diplayed, press DONE to return to normal operation. All of the adjustable parameters in the DC-1 have now been reset to the values assigned when it cleared final Quality Control at the factory.

If you cannot solve functional problems through these procedures, consult your dealer or Lexicon/Customer Service Department.

DO NOT OPEN THE UNIT.

DOING SO WILL VOID YOUR WARRANTY,

AND MODIFICATIONS MAY RENDER THE UNIT UNSERVICEABLE.
