PROGRAMMING  

 

NORMALLY-OPEN MODE. (Image #2) 

This step must be performed if connecting as normally open. 

When the 

Receiver

 is powered on, the relay is in a closed state (normally-closed) by default.  Some ignition systems like the MSD Pro 

Mag 12 need a normally-open relay operation.  This method allows you to change the operation of the 

Receiver

 so that when the 

Receiver

 is powered on, the relay is in an open state and does not allow electricity to flow. 

1)

 

Turn 

Receiver

 off and then back on to determine its current state. Check the 

Receiver

 LEDs immediately after power up. 

a.

 

The yellow LED will illuminate and the Red LED will flash to indicate normally-closed mode. 

b.

 

The yellow LED will illuminate and the Green LED will flash to indicate normally-open mode. 

2)

 

Turn 

Receiver

 and 

Transmitter

 off. 

3)

 

Turn 

Receiver

 ON and make sure the green or red LED is on to show Run or Off mode. Proceed to steps #3 & #4 within 30 

seconds. 

4)

 

Press and hold the RED button on the 

Transmitter

5)

 

Turn the 

Transmitter

 ON via the toggle switch.  

6)

 

Continue to hold the RED 

Transmitter

 button for at least 15 seconds. 

7)

 

The 

Receiver’s

 LEDs will blink to indicate mode change.   

8)

 

Release the red button on the 

Transmitter

 

9)

 

Perform Step #1 in this section to confirm desired mode. 

 

 

STATUS CHECK MODIFICATION 

Transmitter asks the receiver if it is in off or run mode every 30 seconds.  This can be disabled, if desired. 
1)

 

Turn 

Receiver

 and 

Transmitter

 off. 

2)

 

Press and hold the green button on the 

Receiver

3)

 

Turn the 

Transmitter

 on via the toggle switch.  

4)

 

Continue to hold the green button for at least 10 seconds. 

5)

 

The 

Transmitter’s

 LEDs will blink: 

a.

 

If the green LED blinks, the 

Receiver

 is in Status Check Every 30 Seconds mode. 

b.

 

If the red LED blinks, the 

Receiver

 will not check status every 30 seconds. 

 

ADDITIONAL FEATURES 

 

The 

Transmitter

 queries the 

Receiver

 on power-up, during every button press, and every 30 seconds.  30-second check is 

optional; see Programming section. 

 

The 

Transmitter

 will automatically power off after 6 hours of inactivity to conserve the battery.  Turn off and on again to 

reset. 

 

Press the Green button to check range status without shutting off the vehicle
