The Sherlo TX4 remote control is a code hopping 4 button remote, easily identified by the red, blue, green & white buttons. The remote has a strong signal range and is a solid construction.
It uses a 12V GP23AE battery and the LED will flash when the battery is low and needs replacing.
This remote transmits on 433.92mhz. The TX4 remote can replace any of the 1, 2, 3 or 4 button remotes in the range and can also replace the 6 button remote if you are not using more than 4 of the 6 buttons on your current remote.
This remote can be used to operate multiple devices on each button including a gate, garage door and alarm as long as all are using a Sherlotronics 433 receiver.
