IMPORTANT !!! 
Linear radio controls provide a reliable communications link and fi ll an important need in portable wireless 
signaling. However, there are some limitations which must be observed. The radios are required to comply with 
local rules and regulations as radio 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 regulatory 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.
