ML-1402 Marantec Midi 2-Button Remote 40MHz - discontinued
The Marantec ML series of remotes like the ML-1402 2-button midi transmitter was used primarily with the Marantec Mac-Lift Deluxe 2005 and Mac-Lift Elite 2007 garage door openers. They could have also been used in some of the Marantec M-Line M4500 and M4700 openers. Most of these ML-1402 (and ML-1404, ML-2402 & ML-2404) remotes were used in Marantec openers prior to 2003. Some may have been used in other years as the 40MHz frequency remotes were discontinued and stocks were depleted.
All of the 40MHz frequency remotes were discontinued and no replacements are available. None of the "universal" remotes on the market will work so if you have an existing ML-1402 2-button transmitter (or one of the other 40MHz frequency remotes) then you'll need to replace the radio receiver along with the remote.
