Adjust Display and Volume

The audible alert or “beeper” volume can be adjusted to a comfortable level for the operator. The
volume is increased or decreased one step each time the volume key is pressed.

Enter Data
You can enter data into the MX3 through several different methods. The Scanner window
provides barcode data entry, the RS-232 or the IR port are used to input/output data, and the
keypad provides manual entry.
Keypad Entry
Refer to “Appendix A - Key Maps” sections titled “IBM 3270 Specific Maps” and
the “IBM 5250 Specific Maps” for 3270 and 5250 specific keypresses.
The keypad is used to manually input data that is not collected otherwise. Almost any function
that a full sized computer keyboard can provide is duplicated on the MX3 keypad but it may take
a few more keystrokes to accomplish a keyed task.
Almost every key has two or three different functions. The primary alpha or numeric character is
printed on the key.
For example, when the 2nd key is selected pressing the desired second-function key will produce
the 2nd character. The specific 2nd character is printed above the corresponding key.
Please refer to “Appendix A - Key Maps” for instruction on the specific keypresses to access all
keypad functions.
