Setting an ad will replace the Welcome to Store displayed on the white background on the customer's side of the SuperSonic POS.
Go to Store Management and then select Registers.
Here will be the list of registers under the store. On the right hand of the page, next to the register number, select Set Ad.
A new window titled Ad Configuration will appear. The file type of the ad should be a PNG sized to 1400x1400 pixel resolution. Select Choose File and then browse to the location of the PNG picture file on the computer.
