Self-check is used to verify the emulator function works properly. To run the self-check of the emulator, do so as explained

(2) Set the jumpers as the factory-settings to execute the self-check (see Table 2.6).
(3) Within 2 seconds of activating power to the emulator, press the system reset switch on the emulator upper panel.
(4) Check the SAFE LED starts flashing and then press the system reset switch again.
