Original remote control RMT-AH400U (149336511) used for Home Cinema for the brand Sony.
The Sony remote control is not a replica, but an original model of the brand.
The dots found on some keys are called tactile dots or tactile reference points. These dots are designed to help individuals with visual impairments or in low-light situations to identify and use the keys more easily and accurately. Typically, tactile dots are placed on specific keys such as the central number (5) and function keys to facilitate their location and use.
It is emphasized that the remote control has some buttons that work with infrared (IR) and others that use Bluetooth. For the IR keys, it is imperative to have a direct line of sight between the remote control and the device, requiring the remote to be pointed at it. In contrast, functions using Bluetooth do not have this limitation.
It uses 2 batteries of the type AAA
