Problem Possible Causes Possible Solutions
Scanner emits short low-short
medium-short high beep
sequence. Scanner is powering up. Normal when scanner battery is inserted.
Nothing happens when scan
trigger is pressed. No power to the scanner. Check battery.
Ensure that end cap to battery chamber is
secured.
Scanner is disabled. For Simple Serial Interface (SSI), Synapse, or
IBM-468x mode, enable the scanner via the host
interface. Otherwise, call Motorola Enterprise
Mobility Support (see
page xv ) for contact
information).
If using RS-232 Nixdorf B
mode, CTS is not asserted. Assert CTS line.
Laser comes on, but scanner
does not decode the bar code. Scanner is not programmed
for the correct bar code
type. Ensure the scanner is programmed to read the
type of bar code being scanned.
Bar code symbol is
unreadable. Check the symbol to ensure it is not defaced. Try
scanning test bar codes of the same bar code
type. See
Appendix C, Sample Bar Codes for test
bar codes.
Bar code is out of range of
the scanner. Move scanner closer to or further from bar code.
Scanner emits four short high
beeps. Battery is low. Charge the battery. See Charging the Scanner
Battery in the Cradle on page 1-8 .
Scanner emits a disconnect
(short high-short low) beep
sequence. Scanner has disconnected
from cradle because it is too
far from the cradle. Move closer to the cradle and listen for a
reconnection beep (short low-short high).
Scanner has disconnected
from the cradle because the
cradle has lost power or
been placed in USB
suspend mode. Check power connections to cradle, and if using a
USB cable, check to make sure PC has not
entered a power save mode.
