How Do I Calibrate the LINK System Touch Screen (ELO)
Summary
I am unable to select the functions on my LINK System touch screen that I want to select. When
selecting one button, a button that is beside it is selected.
Details
The LINK System’s touch screen may occasionally require a calibration. Calibrating the touch screen
will synchronize the cursor to the point at which your finger touches the screen.
ELO:
IMPORTANT: You will be accessing sensitive areas of the touchscreen's configuration and therefore
must be very careful to follow these directions precisely or risk leaving your unit in a non-functioning
state.
IMPORTANT: It is advisable to read all of the following directions before beginning.
1) Plug in a USB keyboard to the touchscreen. The USB ports can be found underneath the front
part of the unit. You may need to remove the long plastic covering before the ports are
accessible.
2) Return to the default screen for LinkSystem control. You should see three rows of buttons
above the student icons.
3) Press the green button labeled Settings near the top-left corner of the screen.
4) Press the blue button labeled Shutdown in the top-right corner of the screen.
TIMING: You must perform the next step quickly enough to prevent the default operation
(shutdown) from activating. If you miss the timing, you must reboot your touchscreen and
begin again from step #2.
5) Press the d (delay) button on the keyboard. You should see a message indicating that the
system has been placed into a waiting (delayed) state.
6) Hold in the Alt button and press F2. The screen will then prompt you for a login.
7) The login is as follows. Enter the login and password pressing ENTER after each line.
