Transmitter LED




Transmitter LED
The LED on the transmitter provides feedback of system operation and battery condition. The LED flashes in the following sequences:
- One flash indicates that the message was sent and the batteries are OK.
- A quick flashing LED indicates that the convenience opening signal is being sent.
- A slow flashing LED indicates that initialization procedure was successful.
- A steady on LED (after a self test as described on the next page) indicates that the hardware/software of the transmitter are OK.
- No LED activity could indicate discharged batteries or a defective transmitter.
