IR Remote Learning Functions
Alpha VS21 is capable of learning the infrared code of your universal or TV remote control. This will allow you to control the VS21 and your TV with
one remote control. You can integrate the functions of the speaker system to any key of the TV remote control. When selecting the key of choice on the
universal remote for VS21 programming, make sure the functions/commands do not interfere or conflict with other devices like the TV.
Note:
IR Remote Learning may not be compatible with all remote controls.
