Subject: Touch Screen Calibration Changes in Version 4.1 Date: 17 May 07
Status:
Informational Pages: 3
With the release of HFA II-i version 4.1 software, two changes were introduced into the touch screen
calibration:
1)
Feature : The calibration of the touch screen, as entered from the System Setup menu and Additional
Setup menu, operates as before. However, when the pointing device has been held against the
touch screen rectangle, a beep will indicate the new location has been accepted. It will take a few
seconds until the beep is heard.
2)
Problem : During instrument start up, when holding down the patient button, the on-screen message
“To calibrate touch screen release patient switch now” will appear within a few minutes (Figure 1).
For instruments equipped with version 4.1 software, and certain hardware configurations, it will
remain on the screen even after you release the patient button.
Note: The problem will be corrected in a future version of HFA II-i software.
There Are Two Problem Work-Around Processes :
1) Use the touch screen calibration process via the System Setup menu. If this is not possible due to
the inability to select the required buttons on the touch screen, the operator can use a compatible
keyboard to enter the touch screen process, as described below:
a) From the main menu press F6 to enter the System Setup menu.
b) Press the tab key 12 times until the Additional Setup is highlighted.
c) Press the Enter key.
d) Press the tab key 2 times to highlight the Touch Screen Calibration button.
e) Press the Enter key.
f) A warning appears indicating that you are about to calibrate the touch screen with a Continue and
a Cancel button.
g) Press the Enter key to select the Continue choice. The touch screen calibration process will be
started.
h) Follow the on-screen instructions to calibrate the touch screen.
2) Use the hold-down-the-patient-button-at-start-up-touch-screen-calibration process, but
Do Not follow
the instructions displayed on-screen. Instead, follow the instructions below:
a) Hold down the patient switch and power ON the instrument.
b) A screen image “To calibrate touch screen release patient switch now” will appear within a few
minutes (Figure 1).
c) For versions of software other than 4.1, this display will disappear when the patient response
button is released. Instruments equipped with version 4.1 software and certain hardware
configurations, it will remain on the screen even after you release the patient button.
d) Note the small white rectangle in the upper left corner of the display (indicated by the arrow in
Figure 1).
e) Press the pointing device against the center of the white rectangle, in the upper left corner of the
display until you hear a beep.
