IMPORTANT !!!
Linear radio controls provide a reliable communications link and fill
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 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.
NOTE: POWER MUST
