Physical Controls

Programmable Scan Buttons

There are two buttons, one on each side of the display. The buttons can be programmed to perform
specific functions. The programmable keys have no effect on barcode scanners tethered to the
device. When there is no integrated scanner installed, both buttons default to Enter buttons (with
the exception of IBM 5250 terminal emulation devices – in this case, the left button is labeled and
functions as "Field Exit").
Note:
To edit the button parameters, select Start | Settings | Control Panel | KeyPad. Change the
parameter values and tap OK to save the changes.

Field Exit Key Function (IBM 5250/TN5250 Only)

The Field Exit key is used to exit an input field. If the field is an Auto Enter field, the
auto transmit function is activated. This key function is present on the IBM
5250/TN5250 specific keypad only.

Scan Buttons and the SCNR LED

The SCNR LED, located above the keypad, illuminates during an integrated barcode scanner
function. It is affected by internal scanner algorithms.
The Scan buttons have no effect on tethered barcode scanners connected to a serial port. Tethered
scanners read barcode scans only when the trigger on the tethered scanner is pressed. Pressing the
trigger on the tethered scanner has no effect on the mobile device's Scan buttons.
