4. Set the DIP switches on the MDC board on the display controller to address zero (flip all the
switches toward the numbers on the circuit board).
5. Restore power and observe the lamp test.
To exit test mode complete the following steps:
1. Turn off display power.
2. Set address back to original setting.
3. Restore power to display.
Note: The Venus 1500 software, version 2.0 or higher, has a “Test Pixel” option. Refer to ED-
12717.
Lamp Replacement
1. Locate the defective lamp using the testing procedure above.
2. Turn off power to the sign before replacing lamps to avoid damaging the driver.
