This remote with unique design has been discontinued and upgraded to ACDC5 .
Alternatively you can install an add-on receiver MK302 or MK301 then use the pre-programmed remotes coming with the receiver.
This stand-alone radio signal sending and receiving system will be particularly useful if the original receiver inside the drive unit is faulty or works intermittently. Besides, the conversion kit can be installed on different gate or door openers to integrate the control of multi doors or gates.
This one is upgraded to ACDC6.
