Short Cable Version Shown
The RS419 ring scanner is a modular, wearable laser scanner that allows the operator hands-free bar
code scanning capability. The scanner is used with the WT4090 and WT41N0 wearable terminal.
The RS419 is worn on the operator’s index finger, and utilizes a thumb-operated trigger. The
RS419 connects via an interface cable to the wearable terminal, which provides power and
performs the data collection functions. The RS419 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 RS419 rotates to provide left-hand or right-hand
use.
1. Determine whether the RS419 is used on the right or left hand.
CAUTION The trigger assembly only rotates 180° around the
2. Rotate the trigger assembly so that the scan trigger is positioned next to
the thumb when the RS419 is placed on the index finger.
back of the scan assembly. Do not rotate the trigger
assembly past the designed stops.
Installation
The RS419 connects to the wearable terminal and mounts on the index finger.
1. On the wearable terminal, remove the connector cap.
2. Connect the RS419 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 RS419 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
Not to be used in condensing environments.
To scan bar codes:
1. Turn on the wearable terminal.
2. Launch a scanning application.
3. Press the scan trigger and aim the RS419 at a bar code.
The scan LED lights red to indicate the laser is on.
4. Position the red laser beam so that it 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 RS419 farther away from the bar code.
• For bar codes with bars that are closer together, hold the RS419 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 RS419 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.
Release Tab
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.
Replacing the Trigger Assembly
To replace the trigger assembly:
1. Remove the finger strap assembly.
2. Turn the RS419 upside-down.
3. Remove the set screw with
screwdriver.
4. Turn the trigger assembly
counter-clockwise until the exit
window and scan trigger align.
5. Lift the trigger assembly off the scan
assembly.
6. Align replacement trigger assembly
with scan assembly.
7. Rotate trigger assembly 1/4 turn
clockwise.
8. Tighten the set screw with
screwdriver.
9. Replace finger strap assembly.
Cleaning
CAUTION Always wear eye protection.
WARNING! AVOID EXPOSING THIS PRODUCT TO CONTACT WITH HOT OIL
Approved Cleanser Active Ingredients
100% of the active ingredients in any cleaner must consist of one or some combination of the
following: isopropyl alcohol, bleach/sodium hypochlorite
or mild dish soap.
Read warning label on compressed air and alcohol product before using.
If you have to use any other solution for medical reasons please contact
Zebra for more information.
OR OTHER FLAMMABLE LIQUIDS. IF SUCH EXPOSURE OCCURS,
UNPLUG THE DEVICE AND CLEAN THE PRODUCT IMMEDIATELY
IN ACCORDANCE WITH THESE GUIDELINES.

, hydrogen peroxide
IMPORTANT Use pre-moistened wipes and do not allow liquid to pool.
1
When using sodium hypochlorite (bleach) based products always follow the
manufacturer's recommended instructions: use gloves during application and remove
the residue afterwards with a damp alcohol cloth or a cotton swab to avoid prolonged
skin contact while handling the device.
Due to the powerful oxidizing nature of sodium hypochlorite, the metal surfaces on the
device are prone to oxidization (corrosion) when exposed to this chemical in the liquid
form (including wipes). Avoid allowing any bleach based product to come in contact with
the metal electrical contacts on the device, the battery, or the cradle. In the event that
these types of disinfectants come in contact with metal on the device, prompt removal
with alcohol-dampened cloth or cotton swab after the cleaning step is critical.
Harmful Ingredients
The following chemicals are known to damage the plastics on the RS419 and should not come in
contact with the device: ammonia solutions, compounds of amines or ammonia; acetone; ketones;
ethers; aromatic and chlorinated hydrocarbons; acqueous or alcoholic alkaline solutions;
ethanolamine; toluene; trichloroethylene; benzene; carbolic acid and TB-lysoform.
Cleaning Instructions
Do not apply liquid directly to the RS419. Dampen a soft cloth or use pre-moistened wipes. Do not
wrap the device in the cloth or wipe, but gently wipe the unit. Be careful not to let liquid pool around
the display window or other places. Allow the unit to air dry before use.
Special Cleaning Notes
Many vinyl gloves contain phthalate additives, which are often not recommended for medical use
and are known to be harmful to the housing of the RS419. The RS419 should not be handled while
wearing vinyl gloves containing phthalates, or before hands are washed to remove contaminant
residue after gloves are removed. If products containing any of the harmful ingredients listed above
are used prior to handling the RS419, such as hand sanitizer that contain ethanolamine, hands
must be completely dry before handling the RS419 to prevent damage to the plastics.
Materials Required
• Alcohol wipes
• Lens tissue
• Cotton tipped applicators
• Isopropyl alcohol
• Can of compressed air with a tube.

Housing
Using the alcohol wipes, wipe the housing.
Exit Window
Wipe the scanner exit window periodically with a lens tissue or other material suitable for cleaning
optical material such as eyeglasses.
Connector
1. Disconnect the RS419 from the WT41N0.
2. Dip the cotton portion of the cotton tipped applicator in isopropyl alcohol.
3. Rub the cotton portion of the cotton tipped applicator back-and-forth across the connector. Do
not leave any cotton residue on the connector.
4. Repeat at least three times.
5. Use the cotton tipped applicator dipped in alcohol to remove any grease and dirt near the
connector area.
6. Use a dry cotton tipped applicator and repeat steps 4 through 6.
CAUTION Do not point nozzle at yourself and others, ensure the nozzle or tube is
7. Spray compressed air on the connector area by pointing the tube/nozzle about ½ inch away
from the surface.
8. Inspect the area for any grease or dirt, repeat if required.
away from your face.
Cleaning Frequency
The cleaning frequency is up to the customer’s discretion due to the varied environments in which
the mobile devices are used. They may be cleaned as frequently as required. However when used
in dirty environments it may be advisable to periodically clean the scanner exit window to ensure
optimum scanning performance.
