MEGACODE SERIES DIGITAL TRANSMITTERS
The MCT-1, MCT-2 digital transmitters are wireless radio controls designed for
use with automatic garage door and gate openers.
Each of the three transmitter buttons will send a unique code when
pressed. One button can be used to activate the individual's garage door
opener, a second button can operate an access gate, a third button can
activate an additional garage door operator or most Linear 318Mhz wireless
MegaCode transmitters and receivers do not contain a typical "coding
switch". Each transmitter is permanently coded at the factory. The
receiver is programmed by "learning" a transmitter's unique digital code.
The receiver will activate only from the "memorized" transmitters.
The transmitters are powered by two type 2032 lithium "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 a transmitter button is held down.

Moving Door can cause serious injury or death.
· DO NOT
install transmitter unless the door operator’s safety reverse works
as required by the door operator’s manual.
control must be mounted in sight of door, at least 5 feet above floor and
clear of moving door parts.
Keep people clear of opening while door is moving.
NOT allow children to play with the transmitter or door operator.
If safety reverse does not work properly:
Close door then disconnect operator using the manual release handle.
NOT use transmitter or door operator.
to Door and Door Operators Owner’s Manuals before attempting any repairs.
Electrical Shock can cause serious injury or death.
Power cord must be unplugged before
attaching any wires,
Be sure wire ends do not touch each
other or other terminals.
If you have questions or if you need a manual, contact the
distributor or manufacturer of the operator.
PROGRAM RECEIVER & TEST TRANSMITTER
MDR/MDRNR/MDR2 program button and LED location.
Locate the program button and LED on the side of the
MDRM/MDRM2 program button and LED location.
Locate the program button and LED on back of the receiver
Momentarily press the receiver's program button. The red
programming LED will light if there's room in the receiver's memory for
another transmitter (10 max per receiver). The LED stays on for
about 5 seconds. A TRANSMITTER MUST BE
ENTERED WHILE THE LED IS ON. Press the desired transmitter
button. The LED will flicker indicating that the receiver has
accepted the transmitter. NOTE: Be sure to press the
receiver program button for less than 2 seconds (any longer may erase
Add Additional Transmitters.
Repeat the above step for each transmitter used with this
receiver. BE SURE TO PRESS THE RECEIVER'S
PROGRAM BUTTON EACH TIME A NEW TRANSMITTER OR A DIFFERENT TRANSMITTER
BUTTON ON A MULTI-BUTTON TRANSMITTER IS PRESSED. If the LED
doesn't come on when the receiver's program button is pressed, the
receiver's memory is full. Use the erase function to remove
transmitters from the receiver's memory.
ERASING RECEIVER MEMORY.
Transmitters may be erased from the receiver's memory by pressing and
holding the receiver's program button for 5 seconds or more. After
the LED stops blinking all transmitters are erased. Start again
with PROGRAM RECEIVER.
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(s).
CHANGING THE BATTERY
1.When the red LED lights dinly, or not at all when
transmitting, the battery needs to be replaced.
2.Swing the visor clip to the side to clear the battery
3. Remove the battery access door to change the battery.
4. Any type 9 volt battery can be used.
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 transmitter 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 in the device may void FCC compliance.
Infrequently used radio links should be tested regularly to protect
against unidentified interference or fault.
A general knowledge of radio and the vagaries should be gained prior to
acting as a wholesale distributor or dealer, and these facts should be
communicated to the ultimate user.
