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

 

 

PLUS

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.

MINUS

• A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor

 

12-VOLT TYPE 23A
or dealer, and these facts should be communicated to the ultimate users.
