🔔 EVIDENCE BELL

 Field sensor-controlled table bell

 Description
 The Evidence Bell combines a classic table bell with modern sensor technology.
 A three-axis magnetic field sensor continuously monitors the environment. If the tolerance set on the rotary control is exceeded, a solenoid triggers a clear bell chime.
 After each alarm, the device automatically recalibrates itself to the current conditions.

 operation
 1) Set up and switch on – the bell briefly detects the surrounding area.
 2) Adjust the rotary knob – left = less sensitive, right = fully sensitive.
 Tip: Start in the middle position and slowly turn to the right until the desired reaction range is reached.
 3) Operation – if a deviation is detected, the bell rings once; then a short recovery phase, then ready again.
 4) Changed location? Briefly switch off and on again so that the baseline is re-established.
