CP-1 Digital Audio Environment Processor

Problem

Possible Cause and Solution

Restoring defaults

If severe power surges or sags cause problems with CP-1 memory storage, or you simply want to start with a clean slate in the User registers, you can restore factory presets into the User registers with the following procedure. This will erase any programs you have stored in the User register, so you may want to note any settings you wish to re-use before proceeding.

Turn CP-1 power OFF. While pressing PARAM on the Remote Control, turn power ON. (Make sure your hand does not block the infrared receiver on the CP-1 front panel.) Continue holding down PARAM until the display reads:

TEST MODE

PRM Key To Exit

Release PARAM and press EFFECT MUTE to clear and reload User registers, and to restore all factory settings of Volume, Balance, Contrast, Configuration, etc. The display will read:

RESTORE DEFAULTS

Press PARAM to restore normal operation. (Remember to check the LCD contrast and Configuration settings, since they will have been reset to factory defaults.)

If you cannot solve functional problems through these proce- dures, consult your dealer or Lexicon/Customer Service Depart- ment. DO NOT, UNDER ANY CIRCUMSTANCES, OPEN THE

UNIT. DOING SO WILL VOID YOUR WARRANTY, AND MODIFICATIONS MAY RENDER THE UNIT UNSERVICE- ABLE.
