Pressing the STORE button will execute the test.
When the test is executed the remaining buttons, encoders, ADC Pots and footswitches (2) are inactive.
During the execution of the Diagnostics in the Burn In loop, the appropriate test code will be displayed on
the binary LED's. This code will be sent to the LED's before each test is executed. By displaying a test/error
code on the LED's before the test is activated, it will be easier to determine which test failed if the unit
hangs or crashes during the Burn In Loop.
If a test failed, the Burn In Loop will stop and the Binary LED's will display which test failed along with the L
& R Clip (red) LED's lit.
There are three options available when a test has failed during the Burn In Loop:
1. Press the BYPASS button to continue the Burn In Loop.
2. Press the TAP button to run the test continuously.
