Problem
Scanner emits four long low
beeps after scanning a bar
code.
Bar code is decoded, but data
is not transmitted to the host.
Five long low beeps sound
after a bar code is decoded
Scanned data is incorrectly
displayed on the host.
Scanner emits short high-short
high-short high-long low beep
sequence when it is not in use.

Maintenance and Technical Specifications
Possible Causes
Incorrect host interface
cable is used.
Interface/power cables to
cradle are loose.
Scanner is not paired to a
cradle.
Scanner has disconnected.
A transmission error was
detected.
Cradle has not completed
USB initialization.
Scanner not paired to
host-connected cradle.
Cradle not programmed for
correct host interface.
Interface cable is loose.
Cradle has lost connection
to host.
A conversion error or format
error has been detected.
Cradle host communication
parameters do not match
host's parameters.
RS-232 receive error.
Input error or bar
Cancel
code was scanned.
Possible Solutions
Ensure that correct host interface cable is used.
Ensure all cable connections are secure.
Scan the PAIR bar code on the cradle that is
connected to the host that is to receive data.
See disconnect beep sequence above.
Ensure the cradle's communication parameters
match the host's setting.
Wait several seconds and scan again.
Pair the scanner to the cradle (using PAIR bar
code on the cradle).
Check scanner host parameters or edit options.
Ensure all cable connections are secure.
In this exact order: disconnect power supply;
disconnect host cable; wait three seconds;
reconnect host cable; reconnect power supply;
reestablish pairing.
Ensure the scanner's conversion parameters are
properly configured.
Ensure proper host is selected.
For RS-232, ensure the cradle's communication
parameters match the host's settings.
For a Keyboard Wedge configuration, ensure the
system is programmed for the correct keyboard
type, and the CAPS LOCK key is off.
Ensure editing options (e.g., UPC-E to UPC-A
conversion) are properly programmed.
Normal during host reset. Otherwise, ensure the
scanner's RS-232 parity setting matches the host
setting.
Ensure the correct numeric bar codes, that are
within range for the parameter being programmed,
are being scanned.
