Note: The case must be powered on to reset the controller settings. 1. Locate the LAE Controller Display on your specific case. It is typically located near the compressor. 2. Hold down both the i and the x buttons for 5 seconds. The parameter SPL will show on the screen. 3. Tap the button. The screen will show the rES parameter. 4. Hold down the i button.

2 While holding down the button, tap the to change the setting from nO to YES , then release the i button. 5. Tap the x button to return the controller to normal operation. All parameters are now returned to the DEFAULT FACTORY settings. Should you have any questions call killion Customer Service at 1-800-421-5352 or email at .
