Hardware Power Switch
The power switch located in the touch open cover of the main unit is a tactile
pushbutton switch. This switch controls the power on/off of the system. This
switch turns the system on when being pushed only when external power is
present. This switch turns the system off when being pushed again during
power on status. However, if the system hangs due to any reason such as
software resource conflict, a simple push on the switch may fail to turn off the
power. In this case, please utilize the forced power off feature by pressing the
switch and holding for within 10 seconds. In case the turmoil is so vigorous
that some hardware registers may be confused causing trouble for system
restart or even this forced power off, please disconnect the UPS battery if
installed and the AC power supply for few minutes. This may reset all
hardware registers.
Software Support Features
The KS series provides a software power off command for application
program maneuvers. The KS also provides a specific means for the software to
detect if the system is working on external or UPS battery power. Due to this
feature, compatible software applications have the ability to change operating
conditions when running on standard/backup power. The software programmer
may take reference from the KS technical manual to apply such features.
