Maintenance
Smudges and dirt on the unit’s window can interfere with the unit’s performance.
If the window requires cleaning, use only a mild glass cleaner containing no
ammonia. When cleaning the window, spray the cleaner onto a lint free, non-
abrasive cleaning cloth then gently wipe the window clean.
If the unit’s housing requires cleaning, use a mild cleaning agent that does not
contain strong oxidizing chemicals. Strong cleaning agents may discolor or
damage the unit’s exterior.

Cable Installation and Removal
Installation
1. Insert the cable’s modular connector into the socket on the scanner.
2. Pull gently on the cable strain relief to ensure the cable is installed.
Figure 3.
Removal
Turn off power to the host system before removing the cable from the scanner.
1. Locate the small pinhole on the
front side of the scanner nearthe
end of the handle.
2. Bend an ordinary paper clip into the
shape shown.
3. Insert the paper clip (or other small
metallic pin) into the small pinhole.
There will be a faint ‘click’ when the
connector’s lock releases.
4. Pull gently on the cable’s strain
relief to remove the cable.

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.
