IMPORTANT WIRELESS INFORMATION

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.
• 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.
