In fixed code remotes, the code emitted as RF when a button is pressed remains the same constantly. DESi remote controls, on the other hand, use rolling code technology.

Rolling code technology works briefly as follows:

• When you press a button on the rolling code remote control, an encrypted code is emitted as RF.
• When you press the same button again, a different RF code is emitted, also encrypted. The same code is never broadcast again.

DESi remotes, operating on the 433.92 MHz frequency approved by the Telecommunications Authority, offer you comfort and security together.
