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.

✶ 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.
