Indicates...
Normal state
• No Test button press.
Associated; no communication with receiver
• Associated, but no signal from the receiver after pressing Test
button.
Excellent signal strength
• Good signal margin for reliable communication.
Satisfactory signal strength
• Adequate signal strength for reliable communication.
• Moving sensor or receiver may improve signal strength.
• Increased channel switching may reduce battery life.
Poor signal strength
• Unreliable communication.
• Strongly recommend moving the sensor or receiver to a better
location.
