SPECIFICATIONS SUBJECT TO CHANGE WITHOUT NOTICE.
Infrared receiver performance can be degraded if this system is used in close
proximity to high-efficiency lighting equipment with solid state ballasts (i.e. high
efficiency fluorescent) that operate at frequencies with harmonics near 95 kHz.
250 kHz operation should be used when this occurs.
