CP-3 Digital Surround Processor
Troubleshooting
Routine Maintenance
Other than occasional replacement of the batteries in the remote control
units, the CP-3 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-pressure blower
may be used to remove dust from the CP-3 exterior.
Restoring Defaults
If severe power surges or sags cause problems with CP-3 memory storage,
or you simply want to start with a clean slate, you can restore factory presets
into the User registers with the following procedure.
This will erase any programs you have stored in the User registers,
as well as all setup and calibration values.
Note any settings you want to re-use before proceeding.
With the Expanded Remote control, turn the CP-3 OFF. Turn the unit back
ON and press the SETUP button within two seconds. (Make sure you do not
block the infrared receiver on the CP-3 front panel.) Continue holding down
SETUP until the display reads:
* RESTORE MODE *
SETUP TO EXIT
(If you want to resume normal operation without restoring all defaults, this
is your last chance. Release SETUP and press SETUP again to resume
normal operation.)
To restore defaults, release SETUP and press STORE to clear and reload
User registers, and to restore all factory settings of Volume, Balance,
Contrast, Configuration, etc.
The display will flash an INITIALIZING message then read:
* RESTORED ALL *
SETUP TO EXIT
Press SETUP to resume normal operation.
All of the adjustable parameters in the CP-3 have now been reset to the
values assigned when it cleared final Quality Control at the factory. Using
the values notated on the Installation Worksheet at the end of this manual,
follow the initial setup procedure starting on Page 18.
If you cannot solve functional problems through these procedures, consult
your dealer or Lexicon/Customer Service Department.
DO NOT, UNDER ANY CIRCUMSTANCES, OPEN THE UNIT.
DOING SO WILL VOID YOUR WARRANTY,
AND MODIFICATIONS MAY RENDER THE UNIT UNSERVICEABLE.
