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.

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.
5. Insert your index finger through the finger strap. Tighten the strap and press
the hook and pile together.
6. If required, cut excess finger strap material.
