Scanner Operation
Audible Indicators
When the scanner is operational, the scanner provides audiblefeedback to
indicate the status of the scanner and the last scan. Eight settings are available
for the tone of the beep (normal, six alternate tones and no tone).
One Beep – On Power Up
When the unit powers up,the green LED turns on, then the red LED flashes and
the scanner beeps once. The red LED will remain on for the duration of the
beep. The scanner is now ready to scan.
One Beep – During Operation
When the scanner successfully reads a bar code, the red LED will flash and the
scanner beeps once (if programmed to do so). If the scanner does not beep
once andthe red light does not flash, then the bar code has not been
successfully read.
Three Beeps – During Operation
When entering the configuration mode, the red LED flashes whilethe scanner
simultaneously beeps three times. The red LED continues to flash until the unit
exits configuration mode. Upon exiting configuration mode, the scanner beeps
three times and the red LED stops flashing.
When configured for communication timeout, three beeps during operation
indicates that a communication timeout has occurred.

5
Visual Indicators
The scanner is equipped with a red LED and green LED, which indicate the
scanner’s state and the status of the current scan respectively when the unit is in
operation.
Figure 5. LED Location
Green and Red LEDs Are Off
The LEDs will not be illuminated if the scanner is not receiving power from the
host or transformer.
Steady Green
Steady green indicates normal pulse or continuous laser operation.
Accompanied by a razzberry tone, a steady green LED indicates that an invalid
bar code has been scanned.
Flashing Green
After a period of inactivity, the ON time of the pulsing laser will be shortened.
During this time the green LED will flash. This indicates that the scanner is in a
power saver mode. When a bar code enters the laser field, the scanner will
wake up and return to normal pulse mode.
Steady Green and Single Red Flash
When the scanner successfully reads a bar code, the red LED will flash and the
scanner will beep. If the red LED does not flash and the scanner does not beep,
the bar code has not been successfully read.
Steady Green and Steady Red
After a successful read, the scanner transmits the data to the host device. Some
communication modes require that the host inform the scanner when data is
readyto be received. If the host is not ready to accept the information,the
scanner’s red LED will remain on until the data can be transmitted.
Steady Green and Continuous Flashing Red
When entering the configuration mode, the red LED will flash, the green LED will
turn on and the scanner will beep three times. The red LED will continueto flash
and the green LED will stay on until the unit exits the configuration mode.

Failure Modes
One Razzberry Tone – On Power Up
This indicates the scanner has experienced a laser or flipper subsystem failure.
Return the unit for repair to an Authorized Service Center.
Continuous Razzberry Tone with no LEDs
If, upon power up, the scanner emits a continuous razzberry tone, then the
scanner has an experienced an electronic failure. Return the unit for repair to an
Authorized Service Center.
Three Beeps – On Power Up
If the scanner beeps three times on power up, then the non-volatile memory
(NovRAM) that holds the scanner configuration hasfailed. You must return the
unit for repair to an Authorized Service Center.

Verify the bar code being scanned
falls into the configured criteria.
The scanner defaults to a
minimum of three-character bar
code.
Serial Emulation USB Interfaces
The unit scans a
bar code, but
locks up after the
first scan and the
red LED stays
on.
The unit is configured
to support some form
of host handshaking
but is not receiving
the signal.
If the unit is setup to support
ACK/NAK, RTS/CTS, XON/XOFF

Configuration Introduction
Your new scanner has been factory configured with a set of default parameters.
Since many host systems have unique formats and protocol requirements, a
wide range of configurable features that may be selected using this bar code
based configuration tool are provided. Once the configuration is completed, the
scanner stores the settings in nonvolatile memory (NOVRAM). NOVRAM saves
the settings when the power is off.
Note: Bar code descriptions marked with an asterisk ( * ) define a feature that is
afactory default. Bar codes marked with a tilde ( ~ ) require the
Multi-Code configuration method.
Bar Code Configuration Methods
Scanners can be bar code configured in two ways:
the Single-Code Method and the Multi-Code Method.
Single-Code Method
Most features can be enabled or disabled using the Single-Code Method.
1. Power up the scanner.
2. Scan the bar code for the desired feature.
3. The scanner will emit a multi-toned beep to indicate the configuration
has been saved to NOVRAM.
Multi-Code Method
All features can be enabled or disabled using the Multi-Code Method.
Afeature marked with a tilde ( ~ ) requires the Multi-Code Method.
1. Power up the scanner.
2. Scan the Enter/Exit Configuration Modebar code (3 beeps).
3. Scan the bar code for the desired feature (1 beep). Multiple features can
be enabled/disabled before scanning the enter/exit configuration mode
bar code.
4. Scan the Enter/Exit Configuration Modebar code (3 beeps) and save
the new configuration. To abort a configuration change, power off the
scanner before scanning the Enter/Exit code.
