1.7.6 Emergency Operation
If the device enters emergency operation, the speaker is switched “OFF”
due to degraded performance. Depending on settings in installation setup
“LOW BATT” may be indicated if supply voltage drops below a predefined
threshold to indicate to the user, that he should connect his headset as
the speaker may be switched “OFF” soon).In this case, a headset is
