Please note: please do not confuse this blue remote with pink buttons (frequency 433.920 MHz) with the black model with red buttons (frequency 224 MHz), which is no longer manufactured. The colour of the casing and the colour of the buttons determines the frequency for this model. Remote controls with different frequencies are not compatible. This remote control with internal, programmable switches has been advantageously replaced by the most recent model, the Came TOP432NA, which is perfectly compatible.
