You can also use the CK31 diagnostics to help analyze and solve
problems. For help, see Chapter 4, "Running Diagnostics," on
page 95.
If you send the CK31 in for service, it is your responsibility to
save the computer data and configuration. Intermec is
responsible only for ensuring that the keypad and other
hardware features match the original configuration when
repairing or replacing your computer.
Solution
Make sure the contrast is not set all the way to the
•
darkest or lightest setting. Press B and then E
repeatedly until you reach the desired contrast level.
Make sure the backlight is on by pressing E.
•
Make sure you have a charged battery installed
•
correctly.
The battery may be discharged. Replace the battery
•
with a spare charged battery, or charge the battery
and try again.
The battery charge is low. You have a few minutes of
power left. Immediately replace the battery with a spare
charged battery, or charge the battery.
Recalibrate your touch screen. For help, see
"Calibrating the Touch Screen" on page 19.
You may have accidentally locked a modifier key on the
keypad. Check the CK31 taskbar to see if it contains an
icon with a locked symbol. Press the necessary key
sequence to unlock the key. For help, see "Using the
Keypad" on page 7.
The SD card may not be seated correctly. Push in on
the SD card until you hear it unlatch and the card is
ejected. Insert the SD card as described in Steps 3 and 4
of "Installing the SD Card" on page 34. If this does not
solve the problem, try another SD card.
