Problems While Scanning Bar Codes (continued)
Problem Solution
You scan a reader command, such as
Backlight On, and nothing happens.
The reader commands are disabled. Scan the Enable
Override command shown here to temporarily enable all
of the reader commands. When you are finished,
remember to disable the override so that your data is not
interpreted as a command.

You scan a valid bar code label to enter
data for your application. The data
decoded by the scan module does not
match the data encoded in the bar code
label.
The terminal may have decoded the bar code label in a
symbology other than the label’s actual symbology. Try
scanning the bar code label again. Make sure you scan
the entire label.
To operate the terminal quickly and efficiently, you
should enable only the bar code symbologies that you
are going to scan.
Booting the CK30
You seldom need to warm or cold boot the CK30. The CK30
uses the configuration currently saved in flash memory during
the boot process. Once the CK30 finishes booting, your
application appears on the screen.
You need to cold boot the CK30 when an application is locked
up and will not respond, when you upgrade the firmware, or
when you reflash the computer. The next instructions explain
how you warm and cold boot the CK30.
Warm Booting the CK30
If your CK30 does not resume after pressing Power, you may
need to warm boot it.
To warm boot the CK30
• Press and hold the Power key for five seconds. The CK30
will tell you it is performing a warm boot and the screen will
come back up to the splash screen or your application.
