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.

• This device complies with FCC Part 15 and Industry Canada Rules and Regulations. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
