Installation Instructions

DESCRIPTION

The MDTK Digital Keypad is one of Linear’s MegaCode series of wireless

radio controls designed for use with automatic garage door and gate

operators. The MegaCode radio format provides unparalleled security with

more than a million different codes.

In operation, the user enters their unique code on the unit’s keypad (1 to 6

digits long) and presses the START/STOP button to activate the door operator.

For up to 30 seconds after the last activation, the MDTK can be re-triggered by

simply pressing the START/STOP button again. This allows the user to stop or

reverse the opener quickly, without having to re-enter their code.

The MDTK has built-in keypad lighting for use at night or in dark areas. The

clear silicone keys are backlit with a pleasing green glow. By pressing the

START/STOP button ﬁrst, before entering their code, the user can light up

the keypad. Pressing the START/STOP button twice at any time will light up

the keypad.

The keypad lockout timer will disable the keypad after 10 activations. The

keypad must remain idle for 30 seconds before new attempts.

MegaCode receivers are programmed by sending a signal from the user’s

transmitters. This stores the transmitter’s code into the receiver’s memory. The

receiver will retain its memory even without power and will only activate from

these “memorized” transmitters. Each MDTK keypad code can be considered

a different transmitter. Each MegaCode receiver can remember a maximum

of 10 transmitters (40 for gate receivers). Any combination of portable

transmitters and keypad codes up to the maximum number can be entered.

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.
