The Linear MDT-4A is the current and only made five button remote that replaces the MDT-4A MegaCode remote. This remote works with all MegaCode series type garage doors or gate openers that have fixed codes using the 318MHz frequency. The MDT-4A Linear remote controls five garage door openers or gate operators. This is a new item that comes from our bulk purchase pack. This means that it is wrapped in a plastic bag (no box). The remote comes with a visor clip, installed battery and programming instructions.
MDT-4A transmitters do not contain a typical “coding switch”. Each transmitter is permanently coded at the factory to a unique code. The receiver is programmed by making it “learn” the transmitter’s unique digital code. The receiver will activate only from these “memorized” transmitters.
