Solution
Try these possible solutions in order:
• Wait at least 10 seconds and try again. If the CN2A is
still connecting to the Intermec Application Server or
the host, it ignores any input from the keypad or
scanner.
• Press and hold the Power key for 2 to 3 seconds, and
then release it to turn off the CN2A. Press the Power
key again to turn on the CN2A.
• Warm boot the CN2A. For help, see "Warm Booting
the CN2A" on page 111.
• Cold boot the CN2A. For help, see "Cold Booting the
CN2A" on page 112.
• Try reloading the firmware. For help, see "Upgrading
the CN2A" on page 113.
• If the CN2A will not boot or reset, contact your local
Intermec service representative. Before you contact
Intermec, see "Before Calling Product Support" on
page 110.
Try these possible solutions in order:
• Make sure the USB keyboard is either a Dell Model
SK-8115 or a Logitech Model Y-BF37.
• Make sure all cables are securely connected, the CN2A
is firmly seated in the dock, and you are running an
application that accepts keyboard input.
• If the modem dock is attached to an AC power source,
make sure the USB Host Power parameter is set to On
When Powered. If the modem dock is not attached to
an AC power source, make sure the USB Host Power
parameter is set to Always On. For help, see "Attaching
a Keyboard to the CN2A" on page 28.
• Warm boot the CN2A and place it in the dock. For
help, see "Warm Booting the CN2A" on page 111.
