What happens if the buttons on the remote control of the photography digital background do not respond?

Hello:

1. The buttons on the background remote control do not respond. You should first check whether the power supply (battery voltage) of the remote control is sufficient.

2. In addition, if there are obstacles in front of the remote control receiver, they will also block the transmission of infrared rays and cause the remote control to malfunction. Please check carefully and replace the battery.
