Hello everyone, is anyone familiar with ear thermometers, specifically the BRAUN PRO 6000 model?

After installing the batteries, the display flashes and emits five short beeps.

According to Braun, this indicates a system error. I’m just trying my luck here to see if anyone has ever successfully fixed this
