Please match up your megahertz frequency or your ERC number on the back of the remote before ordering as there are two different models, which look exactly the same. For this 433 MHz model, you will receive the new rectangle remote as shown in the second picture and a new control box. Simply unplugged your head and foot motors from your old unit and plug them into the new one and it will work. We will program the remote to the new control box before sending.
