Problems While Configuring the CN3 Computer
Problem Solution
You scan a configuration command, such as Beeper Vol-
ume, and you hear three low beeps.
If you are working in the Intermec Settings applet, you
cannot scan configuration commands. Exit the applet to
scan configuration commands.
You scan or enter an option for the Scanner Model con-
figuration command and you hear three low beeps.
You may have scanned or entered a Scanner Model com-
mand that does not apply to the type of scanner that you
have installed. Try scanning or entering the Scanner
Model command again and select an option for the type
of device you are using.
You cannot type a character on the keypad or you can
only type uppercase or lowercase letters.
You may have locked a modifier key on the keypad.
Check the CN3 toolbar to see if it contains an icon with a
locked symbol. Press the necessary key sequence to
unlock the key. See
“Using the Keypad” on
page 11.
Problems with Wireless Connectivity
Problem Solution
When you turn on the CN3 Computer after it was sus-
pended for a while (10-15 minutes or longer), it can no
longer send or receive messages over the network.
Host may have deactivated or lost current terminal emu-
lation session. In a TCP/IP direct connect network, turn
off the “KeepAlive” message from host to maintain the
TCP session while a CN3 Computer is suspended.
The No Network Connection icon appears on the tool-
bar. The CN3 Computer is not communicating with the
access point.
CN3 Computer is not connected to access point. Ensure
access point is turned on and operating. Move closer to
access point to reestablish communications. Ensure CN3
Computer is configured correctly for network. CN3 radio
parameters must match all access point values (see
page 113).
If you have an 802.11b/g radio and its radio initialization
process failed, reset the CN3 Computer (see
page 3).
If No Network Connection icon still appears, you may
have a defective radio card. For help, contact your local
Intermec representative.
