DESCRIPTION
The MCT-11 MegaCode
®
 digital  transmitter is  a wireless  radio 
control  designed  for  use  with  automatic  garage  and  gate 
operators.
MegaCode
®
  transmitters  and  receivers  do  not  contain  a  typical 
“coding switch”. Each transmitter is permanently coded  at the 
factory. The transmitter  sends a unique code  when the  button is 
pressed. The receiver is programmed by “learning” a transmitter’s 
unique  digital  code.  The  receiver  will  activate  only  from  the 
“memorized” transmitters.
The transmitter is powered by two Type 2032 “coin-cell” batteries. 
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 the transmitter button is 
held down.
PROGRAM RECEIVER & TEST TRANSMITTER
Refer to  the  instructions  provided  with the receiver  to  set  it into 
“learn” mode. With the receiver ready to learn, press the transmitter 
button to program the transmitter into the receiver’s memory. 
After programming, test the transmitter from various locations. 
Be 
sure the  door or  gate areas  are clear.  Activate  the transmitter 
and verify that the receiver triggers the operator.

IMPORTANT !!!
Linear radio controls provide a reliable communications link and fill 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 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.
