Chamberlain Liftmaster TX4UNIF 4 Channel Universal Transmitter 433MHz.

The TX4UNIF universal transmitter has a white LED indicator and operates on the 433MHz frequency. As a universal transmitter, it can be used for the entire Evolution series and older drives (with 433MHz from 1997). The transmitter has a design based on a modern and attractive vehicle key. The big buttons of the universal transmitter also increase ease of use and offers additional comfort whilst making it possible to control up to four doors. The matt black colour provides a very elegant accessory that one is proud to carry on the key chain. The TX4UNIF universal transmitter can be used with most Chamberlain, Liftmaster and Motorlift operators with Billion, Rolling or EVO code technology.

This universal remote control is equipped with a special code and can access all Chamberlain Liftmaster garage door openers and gate operators, with Chamberlain 433MHz receivers.

Please note, this is NOT compatible with models LM50K, ML510 and HE500AN.
