All diagnostic functions are completed via wireless communication between the EZ-DT and EZ-1 decoders. To read decoder information:

1. Manually activate the desired station to energize the two-wire path.
   • ICC2 Manual Operation
   • HCC Manual Operation
   • PC400 Manual Operation
2. From the HOME screen, select READ.
3. Position the EZ-DT and EZ-1 decoder as shown in the display. Select ENTER.

4. Two beeps will sound, and decoder information will be displayed. If the decoder reading fails, a red X will appear in the display. If the LED on the decoder is not blinking green, ensure the station is active, check the two-wire path and wire connections, and repeat steps 1 & 2.
