IMPORTANT !!!
Willis 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 modifications 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.
