Introduction
The Symbol LS4278 scanner combines excellent scanning performance and
advanced ergonomics to provide the best value in a lightweight laser scanner.
Whether used as a hand-held scanner or in hands-free mode in a stand, the
scanner ensures comfort and ease of use for extended periods of time. Before
programming the scanner, scan the appropriate bar code(s), beginning on page 8,
to communicate with the host.

Scanning
Beeper Definitions
The scanner issues different beep sequences and patterns to indicate status. The
table below defines beep sequences that occur during both normal scanning and
while programming the scanner.
Beeper Sequence Indication
Standard Use
Low/medium/high beeps Power up.
High beep A bar code symbol was decoded (if decode beeper is
enabled).
Four long low beeps A transmission error was detected in a scanned symbol.
The data is ignored. This occurs if a unit is not properly
configured. Check option setting.
Five low long beeps Conversion or format error.
Low/high/low beeps ADF transmit error.
High/high/high/low beeps RS-232 receive error.
Parameter Menu Scanning
Long low/long high beeps Input error, incorrect bar code or “Cancel” scanned, wrong
entry, incorrect bar code programming sequence; remain
in program mode.
High/low beeps Keyboard parameter selected. Enter value using bar code
keypad.
High/low/high/low beeps Successful program exit with change in the parameter
setting.
Long low/long high/long low/long
high beeps
Out of host parameter storage space. Scan Set Defaults
on page 8.
Wireless Operation
High/low/high/low beeps Pairing bar code scanned.
Low/high beeps Bluetooth connection established.

LED Definitions
In addition to beeper sequences, the scanner communicates with the user using a
two-color LED display. The table below defines LED colors that display during
scanning and charging.
High/low beeps Bluetooth disconnection event.
Long low/long high beeps Page timeout; remote device is out of range/not powered.
Long low/long high/long low/long
high beeps
Connection attempt was rejected by remote device.
Code 39 Buffering
High/low beeps New Code 39 data was entered into the buffer.
Three long high beep Code 39 buffer is full.
Low/high/low beeps The Code 39 buffer was erased or there was an attempt to
clear or transmit an empty buffer.
Low/high beeps A successful transmission of buffered data.
Host Specific
USB only
Four high beeps Scanner has not completed initialization. Wait several
seconds and scan again.
Scanner gives a power-up beep
after scanning a USB Device Type.
Communication with the bus must be established before
the scanner can operate at the highest power level.
This power-up beep occurs more
than once.
The USB bus may put the scanner in a state where power
to the scanner is cycled on and off more than once. This is
normal and usually happens when the host PC cold boots.
RS-232 only
High beep A <BEL> character is received and Beep on <BEL> is
enabled.
Scanning LED Indication
Green Flash A bar code was successfully decoded.
Charging LED Indication
Green - Slow Continuous Flash Non-critical battery temperature fault.
Green - Fast Continuous Flash Scanner is charging.
Green - Solid Scanner is fully charged.
Amber - Continuous Flash Critical battery temperature fault.

Troubleshooting
Problem Possible Cause Possible Solutions
LED indicates a
battery temperature
fault.
Battery is above or
below normal
operating
temperature.
Do not use the scanner. Move the scanner to a
location within normal operating temperature.
The scanner can remain in the cradle while the
battery warms or cools to normal operating
temperature. Refer to the Product Reference
Guide for more information.
Nothing happens
when the trigger is
pulled.
No power to the
scanner.
Battery may be discharged; charge scanner in
cradle.
Check that battery door is closed
Ensure that end cap to battery chamber is
secured.
Scanner is disabled. Some host interfaces (e.g., Synapse, IBM-468x)
can disable the scanner. If this applies, enable
the scanner via the host interface.
Laser comes on,
but symbol does not
decode.
Scanner is not
programmed for the
correct bar code
type.
Ensure the scanner is programmed to read the
type of bar code scanned.
Refer to the Product Reference Guide for more
information.
Bar code symbol is
unreadable.
Check the symbol to ensure it is not defaced. Try
scanning test symbols of the same bar code type.
Distance between
scanner and bar
code is incorrect.
Move the scanner closer to or further from the bar
code.
Symbol is decoded
but not transmitted
to the host.
Cradle is not
programmed for the
correct host
interface.
Check scanner host parameters or edit options.
Scanner not paired
to host-connected
interface.
Pair the scanner to the cradle (using PAIR bar
code on the cradle).
Interface cable is
loose.
Ensure all cable connections are secure.
Cradle has lost
connection to host. In this exact order: disconnect power supply;
disconnect host cable; wait three seconds;
reconnect host cable; reconnect power supply;
reestablish pairing.
Scanned data is
incorrectly
displayed on the
host.
Scanner is not
programmed to work
with the host.
Ensure proper host is selected.
Check the scanner’s host type parameters or
editing options.
For RS-232, ensure the scanner’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.
Refer to the Product Reference Guide for more
information.

Programming Bar Codes
Following are some frequently used programming bar codes.
Set Defaults
Scan SET DEFAULTS to set all parameters to their default values.
SET DEFAULTS
Scanning Modes
Scan the appropriate bar code below to determine the scanning pattern.
•SINGLE LINE ONLY - No up and down scan line movement (no raster).
•MULTI-LINE SMART RASTER - The scan line begins as a single line and
moves up and down (rasters) when a partial scan of a bar code is detected, or
no bar code is decoded 500 ms after the trigger is pulled.
•MULTI-LINE ALWAYS RASTER (default) - Rastering (up and down scan line
movement) begins immediately.
SINGLE LINE ONLY
MULTI-LINE SMART RASTER

NOTE For additional host types, refer to the Symbol LS4278 Product
Reference Guide, p/n 72E-69834-xx, available on the
Symbol LS4278 CD, or on the website:

Quick Reference Guide 9
Host Types
If a Synapse cable is used (i.e., part number STIxx-xxxx), the scanner autodetects
the Synapse cable and there is no need to scan bar codes to enable the Synapse
host.
If a USB interface is used, the scanner autodetects the USB and defaults to the
HID keyboard interface. See page 12 to select the IBM hand-held host type.
If a Keyboard Wedge, RS-232, Wand Emulation, Scanner Emulation, or IBM
46XX is used, the appropriate host type must be scanned. Select the appropriate
host type from the bar codes that follow.
