The software will automatically switch to the backup amplifier channel and report a fault. This is displayed in both the log viewer and the call station's graphical user interface.

In addition, now it is also possible to control the brightness of the LCD screen of the call station, the luminous rings and all the fault and status LEDs, through an up/down setting on the call station extension keyboard. There are four levels designed for conditions ranging from daylight to full darkness.

Moreover, Praesensa has received DNV-type approval (Det Norske Veritas) to meet the specified cruise requirements, boats and oil rigs.
