Shutting Down the P1220
It is
highly recommended to
properly shut down
the P1220 to avoid operating system corruption due to hard
power loss. To shut down the P1220, complete the following steps:
1.
If using a software application, typically there is a software shutdown button in the manager’s setup screen
which should be used to properly shut down the terminal. If a shutdown button does not exist, then exist
the application to the operating system and shut down gracefully through the operating system (see #2
below)
2.
Properly shut down your operating system. For Windows operating systems (XP-Embedded and XP-
Professional), you can do this by selecting
Shut Down
from the
Start
menu.
NOTE:
The above steps may vary depending on your installed operating system and software application.
3.
If proper shutdown through the software application or operating system is not achievable. Then, press the
“On/Off” button located on the I/O connectivity panel at the bottom P1220. This will create an operating
system shutdown.
4.
If none of the options above are responding or simple not available, then unplug the terminal from the
outlet. Note: This should be avoided at all times to avoided operating system corruption due to hard power
loss.
Touch Calibration
The P1220 with resistive or capacitive touch screen will already be calibrated before it ships from Radiant
Manufacturing. It should not require a recalibration through the life of the terminal. However, if touch issues
arise, it is recommended that re-calibration be tried first before returning the terminal.
To determine if you have resistive or capacitive touch screen is to gently touch the screen with an object
different from a finger. This could be a plastic part of a pen, cardboard, etc. Resistive screens will accept all
input devices including finger or styluses whereas capacitive will just accept finger and/or conductive input
devices. If the plastic part of the pen does not register a touch, the terminal is likely to have a capacitive touch
screen which requires finger input for best results.
Resistive touch screen
For resistive touch screen, Radiant uses 4 point calibration to achieve the best accuracy. The below steps
outline how to re-calibrate the touch screen. Note: Do not use any sharp objects, pens, pencils, or any material
expect a finger to contact touch screen sense it could damage the touch sensing layer.
With a Radiant application, from the managers menu, select
calibrate touchscreen
.
From the
desktop or startup menu

type:
tcalib
You can also run the tcalib from the P15xx folder.
