After restarting the OBP60, you may hear a continuous beeping sound from the keys. This is because one of the keys is constantly being triggered because the sensor value is above the switching threshold. It has not yet been determined what causes the higher sensor value. It can be caused by moisture on the keys or in the housing, for example, or by dirt on the keys.

The problem can be eliminated by reducing the sensitivity threshold for the keys from 100% to 70%.

A revision of the software for key detection would be useful. When booting, the current sensor values ​​of all keys could be read out and the sensitivity setting could be standardized to these values. This would standardize the sensitivities of all keys and adapt to any changes that occur.

Disassembly of the device and tweaking the aluminum foil fixes this issue (at least temporarily)
