3.1.1

Calibrating the touch screen

It may occasionally be necessary to calibrate the touch-screen, so that the pressure sensitive
spots on the screen accurately overlay the icons. It is recommended to calibrate the touch-screen
the first time you use it. The touch-screen can be recalibrated at any time, if needed.
To calibrate the touch screen, press and hold your finger on any location on the screen
(preferably not on an icon) for 10 seconds and then release your finger. The software then
prompts you to press on four specific locations on the screen, in series. Upon completing this
process, the touch screen has been calibrated.
3.2

Alarm Off button

To the left side of the LCD touch screen are two buttons. The leftmost button is the "Alarm Off"
button. Pressing the "Alarm Off" button silences the alarm that sounds when there is a system
fault. If another fault occurs, the alarm returns to active mode.
Note: The ALARM LED remains lit until the problem is resolved to indicate the continued existence of a
system fault.
3.3

CPU On/Off button

To the left of the LCD touch screen are two buttons. The rightmost of these is the "CPU On/Off"
button. Pressing this button switches the UPS's main computer (the CPU) off or on. This is for
use only in the rare instance that the LCD touch screen freezes up or the system otherwise
ceases to respond to commands. In such a case, switching the CPU off and then on again may
resolve the problem.
The Centric will continue to operate as normal even when the computer is turned off, although
obviously there will be reduced functionality.
3.4

USB1 and USB2 connectors

To the right of the LCD touch screen are two USB connectors. These are described in section
XX.
