words of caution and limitations of infrared
Be sure that the path of transmission between the emitter and sensor is not obstructed.
The Sapphire pendant transmitter will not function if placed in pocket.
Infrared will not work outdoors in sunlight.
Dark surfaces will not reflect infrared well and can limit distance of transmission.
Rooms larger than 1600 Sq. Ft or have high ceilings can begin to exceed the ultimate
performance of the Quantum II.
If dropouts are experienced in areas, as additional sensor ICS-55 sensor can extend the system
performance.
