DATA VALIDATION AND NOISE DETECTION
This section describes how to determine if the radio frequency environment is too noisy for a radio
operated system.
A. DATA VALIDATION AND NOISE DETECTION
The Data Validation and Noise Detection LEDs are located on the controller board to the left of the
keypad. The yellow LED is labelled DATA, and the red LED is labelled NOISE.
•
When a transmitter button is pressed the yellow DATA LED should light, and the red NOISE
LED may also light. This is normal.
•
If a transmitter button is pressed and the red NOISE LED lights but the yellow DATA LED
does not light, there is too much interference for the transmitter to be detected by the
receiver.
