IMPORTANT

Linear radio controls provide a reliable communications link and 
fi ll an important need in portable wireless signalling. However, 
there are some limitations which must be observed.
•  For U.S. installations only: The radios are required to comply 

with FCC Rules and Regulations as Part 15 devices. As such, 
they have limited transmitter power and therefore limited 
range.

•  A receiver cannot respond to more than one transmitted signal 

at a time and may be blocked by radio signals that occur on or 
near their operating frequencies, regardless of code settings. 

• Changes or modifi cations to the device may void FCC 

compliance.

•  Infrequently used radio links should be tested regularly to 

protect against undetected interference or fault.

•  A general knowledge of radio and its vagaries should be 

gained prior to acting as a wholesale distributor or dealer, and 
these facts should be communicated to the ultimate users.
