If the LED indicator does not flash:
- Relocate the repeater and/or Monitor/Sensor. The products must be within 330 ft (100 m) of each other.
- Make sure products (Repeater, display, Monitors, Sensors) are placed at least 3 feet (.9 m) away from electronics that may interfere with the wireless communication (such as TVs, microwaves, computers, etc).
- Use standard alkaline batteries (or lithium batteries in Repeater, Monitors and Sensors when temperature is below -4ºF/-20ºC). Do not use heavy duty or rechargeable batteries.
NOTE: It may take a few minutes for repeater and sensors to synchronize after batteries are replaced.
