The B 500 Professional has an independent monitoring system that gives you the possibility of spotting
errors quickly and reacting accordingly.
The fault display can be combined with an acoustic signal so that a "beep" can be heard in addition to the
display being shown. You can select this setting yourself. Please refer to the section on "Menu program-
ming".
The following fault codes tell you what problem has occurred and what has to be done.
Note: If a fault code is displayed, only the On/Off button and the PROG and SET key on the remote control
unit can be used.
