	Startup Procedures (contd.)

Figure 7. Control Board and Fuse Assembly

To start up the Radio Control unit, perform the following procedure:

1.Action: Turn power switch to ON.

Result: Red power-on light should light. Timer light may or may not come on. Since the timer module uses electronic memory, and since this memory comes on in a random fashion at initial turn on, the unit must be operated once to put all circuits in proper order.

2.Action: Turn Timer Test Switch S2 to FAST.

3.Action: Depress Test Pushbutton S3 three times within 5 seconds.

Result: The 3-pulse relay should close.
