number. Refer to the receiver’s documentation for details on
registering a transmitter.
When prompted by the receiver to reset the transmitter, press the
reset button on the transmitter. Refer to Figure 2 on page 1.
Test the transmitter after it is registered with the
system.
To test the transmitter, activate each of the
conditions and ensure an appropriate response.
