Using the File Directory
A file directory appears whenever you want to perform a specific
function with previously saved tests. Buttons such as VIEW TESTS,
COPY TESTS, and CHANGE PATIENT DATA will bring up file directories.
To select specific items on a directory, move the cursor to the desired
item. Then, either select with your fingertip or click the glidepad
button to highlight the item. If you can select more than one item,
such as with the COPY TESTS feature, a check mark (
✔
) will appear
next to an item to indicate that it has been selected.
You can select several items in a row at one time. To do so, either
touch the first item and drag your fingertip down the list, or hold
down the glidepad button, drag the cursor to highlight and check (
✔
)
several items, and then release the button. After dragging with either
method, only the last item will remain highlighted; however, each item
selected will have a check mark next to it.
To deselect a chosen item with your finger, just touch the item you wish to deselect. The check mark
next to the item will disappear. For the glidepad, move the cursor to a highlighted or checked (
✔
)
item and click the glidepad button.
Screen Saver
The HFA II- i features a screen saver to extend the life of the video screen. It activates after the HFA
II-
i
has been idle for 10 minutes. Once the screen saver is activated, the display of the HFA II-
i
becomes dark. To reactivate the display you only need to press a fingertip to the top of the touch
screen. Try to avoid touching the center of the touch screen because this could activate a hidden
command key. For example, many messages include a CANCEL button. If there is an ongoing
operation and you press near the middle of the screen, you may unintentionally cancel the
operation.
You may also move the glidepad or press most keys on the external keyboard to reactivate the
display. Make sure you do not press the ENTER / RETURN key or the SPACE BAR to wake-up the
display. These keys will activate any command buttons hidden by the darkened touch screen.
