Operation
Keypad Operation
In the default application supplied with the RF scanner, the keypad is enabled. If your
application has enabled the keypad, you can enter the bar code’s data using the keypad on
the top of the scanner. To enter numeric characters, press the number key on the keypad. A
high-pitched click lets you know that the entry was accepted. See Figure 3-3 on page 3-6.
To enter alpha characters, press the MODE key once to put the scanner in Alpha Mode. Press
the numeric key with the letter you want above it - once for the first letter, quickly twice for
the second letter, or quickly three times for the third letter. Every time you press the key, you
hear a low-pitched click to let you know that the entry was registered but not accepted yet,
and a high-pitched key click after a second or so to let you know that the entry was accepted.
You can go from one key to another before hearing the high key click (i.e., from the “a” to
the “d”), but you must first hear the high click to go to a different letter on the same key (i.e.,
the “a” to the “c”).
To return to numeric mode, press the MODE key again.
To put a decimal point into numeric data, type in the numbers before the decimal point. Then
press the Shift key, press the decimal, and press the Shift key again. Now resume typing in the
numeric entry.
The * key and the “FNumber” key combination are special keys that can be
programmed for custom operations. To use the “FNumber” key combination, press
the Function key, release it, and then press the number key associated with the operation to
perform. For more information on how to program these keys and what they mean, refer to
the
MCL Designer User’s Guide .
