ST30 system phones with illuminated display
System phones


Since August 2000 ST30 system phones as from serial number 32912 have been shipped with illuminated displays.

As from firmware release 3.5 on the AS40, the display illumination is selective (always on; on when an action is performed; off) !

As well as the relevant terminal equipment (for serial number see above), to support this feature firmware 2.0c or higher is also required in the system phones used.

If you are using system phones which do not yet have that firmware release, you can update them by way of our update server by calling +049 521 44709950 !
