Introduction
The RS409 ring scanner is a modular, wearable laser scanner that allows the
operator hands-free bar code scanning capability. The scanner is used with the
WT4070/90 wearable terminal.
The RS409 is worn on the operator’s index finger, and utilizes a thumb-operated
trigger. The RS409 connects via an interface cable to the wearable terminal,
which provides power and performs the data collection functions. The RS409 is
available in two configurations; a short cable version for connection to a wrist
mounted wearable terminal, and a long cable version for connection to a hip
mounted wearable terminal.

Changing Trigger Position
The trigger assembly of the RS409 rotates to provide left-hand or right-hand use.
1. Determine whether the RS409 is used on the right or left hand.
2. Rotate the trigger assembly so that the scan trigger is positioned next to the
thumb when the RS409 is placed on the index finger.
CAUTION The trigger assembly only rotates 180° around the back of the
scan assembly. Do not rotate the trigger assembly past the
designed stops.

Installation
The RS409 connects to the wearable terminal and mounts on the index finger.
1. On the wearable terminal, remove the connector cap.
2. Connect the RS409 interface cable to the wearable terminal interface
connector. If connecting to a wrist mounted wearable terminal, connect to the
interface connector closest to the wrist.
3. Slide the RS409 onto the index finger with the scan trigger next to the thumb.
4. Tighten the finger strap.

5. If required, cut excess finger strap material.
6. Warm boot the wearable terminal.
Using the Scanner
To scan bar codes:
1. Turn on the wearable terminal.
2. Launch a scanning application.
3. Press the scan trigger and aim the RS409 at a bar code.
The scan LED lights red to indicate the RS409 is on.
4. Adjust the aim so that the thin, red laser beam covers the entire length of the
bar code.

5. If the decode is successful the LED turns green. The terminal beeps if
programed accordingly.
Scanning Tips
• For larger bar codes, hold the RS409 farther away from the bar code.
• For bar codes with bars that are closer together, hold the RS409 closer to the
bar code.
• The optimal scanning distance varies with bar code density, but 10 to 25 cm (4
to 10 inches) generally works. Practice to determine what distances to work
within.
• Do not position the RS409 exactly perpendicular to the bar code being
scanned. In this position, reflected light can bounce back into the exit window,
and possibly prevent a successful decode.
Finger Strap Assembly Replacement
The finger strap assembly can be changed for each user or for replacement. To
replace the finger strap assembly:
1. Press down on the finger strap assembly release tab.
2. Slide the finger strap assembly out of the trigger assembly.
3. Align a new finger strap assembly with the slot in the trigger assembly.
4. Push the finger strap assembly into the trigger assembly until the release tab
clicks into place.

Cleaning
Wipe the exit window periodically with a lens tissue or other material suitable for
cleaning optical material such as eyeglasses.
Troubleshooting
CAUTION Do not pour, spray, or spill any liquid on the RS409.
Symptom Probable Cause Action
Laser beam does
not display when
pressing the
trigger.
Interface cable is not
secure. Verify that the interface cable connection is connected
properly.
Power is not applied to
RS409. Power for the RS409 is provided by the wearable
terminal. Verify that the
wearable terminal has a
charged battery installed.
Scan enabled
application on the
wearable terminal is not
running.
Launch scanning application
on the wearable terminal.
RS409 does not
decode a bar code. Bar code is unreadable. Verify that the bar code is not defective, i.e., smudged or
broken.
Exit window is dirty. Clean exit window with a lens
tissue. Tissues for
eyeglasses work well. Do not
use tissues coated with lotion.
Symbology is not
enabled. See your system administrator.
