FCC/CE notice
Certain rules must be observed: devices that use radio waves must conform
to the rules and regulations. As such, the power of the transmitter is limi-
ted. A receiver cannot respond to more than one signal at a time and can
therefore be disrupted by radio signals similar to its operating frequencies.
