Front Panel Test Mode
If the top left and top right buttons are both pressed and held while power is connected to
the unit, the Model 6203 enters a test mode. The Test Mode is indicated by the state of the
LEDs in the fourth row down from the top (ON SCENE). When the Model 6203 is in test
mode, these LEDs are on at start-up. The test mode can be used to test the following:
• Relays
• Sense Inputs
• Buttons
• LEDs
This mode of operation is brought up here because being able to manually cycle relays or
check the status of sense inputs might come in very handy while you are wiring up I/O
connections to the relays and sense inputs.
