Scan Buttons
Figure 2-5 Scan/Enter/FLD EXIT Buttons
There are two buttons, one on each side of the display. The buttons are programmable. Depending
on the type of unit purchased (e.g. IBM specific or batch), the buttons will function as an internal
barcode scanner key or a numeric keypad Enter key. Scan keys have no effect on scanners
tethered to the MX3.
The 5250/TN5250 specific MX3 uses the left scan key as the Field Exit key. It is labeled FLD
EXIT.
See next section titled “Keypads”, subsection “Programmable Buttons”.
Scan Buttons and the SCNR LED
The SCNR LED, located above the keypad, illuminates during a barcode scanner function. It is
affected by internal scanner functions. The 5250/TN5250 specific MX3 FLD EXIT button, when
pressed, has no effect on the SCNR LED.
• Red - scanning.
• Green - good scan.

Figure 2-6 Speaker Location
The MX3 Speaker has a loudness of at least 90 dB at 10 cm measured from the front of the unit.
The Speaker volume is adjustable via the keypad or by the application through the use of an API
call. There are 8 distinct volume levels. The minimum volume level is 0 (no sound) with a default
setting of midrange. The volume sticks at maximum and minimum levels. The Speaker beeps
when the main battery is low otherwise it is under the control of the application and other software
currently active.
