5.1 Overview
5.1.1 Tips for the use of the touch screen
The entire screen is touch-activated. To make a selection, press the
screen with a fingernail, fingertip, pencil eraser or a stylus. Do not
press the screen with a sharp object, such as the tip of a ball
point pen.
• Do not place anything on top of the screen, to prevent damage
or scratching on the screen.
• Press keys, words or icons to select them.
• Use scroll bars to move up and down long lists very quickly.
Press and hold the scroll bar, then move up or down to move
through the list.
• Highlight an item from a list by pressing it once. When the item
has been successfully selected, it will be displayed as reversed
text (light text on a dark background).
5.1.2 Use of the alphanumeric keypad
This display is used to enter letters, numbers and symbols as
needed when programming the instrument. Unavailable options are
disabled (grayed out). The icons on the right and left of the screen
are described in Table 1.
The central keypad changes to reflect the chosen entry mode.
Press a key repeatedly until the desired character appears on the
screen. A space can be entered by using the underscore on the
YZ_ key.
Note: A USB keyboard (with US keyboard layout) or a USB Barcode
handset scanner can be used for input (see Section 9 on page 129).
