Example of how the "Amber Series" functions

Upon starting your vehicle the display initially shows you a vehicle voltage reading. After approximately 50 seconds the display switches over to display the vacuum reading. In 10 minute intervals the display reverts back to show you a vehicle voltage rating that is displayed for 50 seconds beforevacuum is once again shown. During the 50 seconds that the voltage figure is displayed you are still able to monitor vacuum by viewing the LED bar display.

Should the vehicle voltage at any point drop below 11V the display with begin to flash with a red warning light and the current voltage will be shown. The voltage display mode will remain until the problem has been corrected.
