factory. The receiver is programmed by “learning” a transmitter’s  
unique digital code. The receiver will activate only from the  
“memorized” transmitters.

They should last 3 years with normal use.The red indicator on the  
face of the transmitter will glow when the unit is activated. If the  
indicator lights dimly, or not at all when transmitting, the batteries  
need to be replaced.To conserve battery life, an internal timer limits  
the transmission duration to 10 seconds if a transmitter button is  
held down.

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.  
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.
