A close inspection of the tactile button side of the PCB revealed two small holes. These small holes turned out to be port openings for dual MEMS Microphones found in the remote.

Also, found during the close inspection of tactile button side of the PCB was that the two horizontal buttons on the front face of the remote are also able to contact tactile buttons above and below the tactile button they rest on, which means that the user can push down, push up, or pull down when using those buttons.

A LED was also located near one of the Microphone port holes.
