Maintenance and

Troubleshooting

Introduction

This chapter includes instructions on cleaning and storing the device, battery maintenance and provides troubleshooting solutions for potential problems during device operations.

Maintaining the WT6000

For trouble-free service, observe the following tips when using the WT6000:

• Protect the WT6000 from temperature extremes.

• Do not store or use the WT6000 in any location that is extremely dusty, damp, or wet.

• If the surface of the WT6000 screen becomes soiled, clean it with a soft cloth moistened with a diluted window-cleaning solution. Do not use bleach, ammonia or hydrogen peroxide products.

• Take care not to scratch the screen of the WT6000.

• The display of the WT6000 contains glass. Take care not to drop the WT6000 or subject it to strong impact.

Battery Safety Guidelines

• The area in which the device units are charged should be clear of debris and combustible materials or chemicals. Particular care should be taken where the device is charged in a non-commercial environment.

• Do not use incompatible batteries and chargers. If you have any questions about the compatibility of a battery or a charger, contact Zebra Support. See

<em_Emphasis>Service Information on page 12 for

contact information.

• Do not crush, puncture, or place a high degree of pressure on the battery.

• Follow battery usage, storage, and charging guidelines found in the device Quick Reference Guide.

• Improper battery use may result in a fire, explosion, or other hazard.

• To charge the mobile device battery, the battery and charger temperatures must be between +32°F and

+104°F (0°C and +40°C)

• Do not disassemble or open, crush, bend or deform, puncture, or shred.

• Severe impact from dropping any battery-operated device on a hard surface could cause the battery to overheat.

• Do not short circuit a battery or allow metallic or conductive objects to contact the battery terminals.

154

Maintenance and Troubleshooting

• Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse or expose to water or other liquids, or expose to fire, explosion, or other hazard.

• Do not leave or store the equipment in or near areas that might get very hot, such as in a parked vehicle or near a radiator or other heat source. Do not place battery into a microwave oven or dryer.

• Battery usage by children should be supervised.

• Please follow local regulations to promptly dispose of used re-chargeable batteries.

• Do not dispose of batteries in fire.

• Seek medical advice immediately if a battery has been swallowed.

• In the event of a battery leak, do not allow the liquid to come in contact with the skin or eyes. If contact has been made, wash the affected area with large amounts of water and seek medical advice.

• If you suspect damage to your equipment or battery, call Customer Support to arrange for inspection. See

<em_Emphasis>Service Information on page 12 for contact information.

Cleaning

CAUTION : Always wear eye protection.

Read warning label on compressed air and alcohol product before using.

If you have to use any other solution for medical reasons please contact Symbol Technologies for more information.

WARNING

: Avoid exposing this product to contact with hot oil or other flammable liquids. If such exposure occurs, unplug the device and clean the product immediately in accordance with these guidelines.

Approved Cleanser Active Ingredients

100% of the active ingredients in any cleaner must consist of one or some combination of the following: isopropyl alcohol, or mild dish soap.

Harmful Ingredients

The following chemicals are known to damage the plastics on the device 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, TB-lysoform, bleach products and hydrogen peroxide.

Cleaning Instructions

Do not apply liquid directly to the device. 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 device. The device should not be handled while wearing vinyl gloves containing

155

Maintenance and Troubleshooting 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 device, such as hand sanitizer that contain ethanolamine, hands must be completely dry before handling the device to prevent damage to the plastics.

Cleaning Materials Required

• Alcohol wipes

• Lens tissue

• Cotton tipped applicators

• Isopropyl alcohol

• Can of compressed air with a tube.

Cleaning the WT6000

Housing

Using the alcohol wipes, wipe the housing.

Display

The display can be wiped down with the alcohol wipes, but care should be taken not to allow any pooling of liquid around the edges of the display. Immediately dried the display with a soft, non-abrasive cloth to prevent streaking.

Power Connector

Remove the main battery from the WT6000.

Dip the cotton portion of the cotton tipped applicator in isopropyl alcohol.

Rub the cotton portion of the cotton tipped applicator back-and-forth across the connector inside the handle of the WT6000. Do not leave any cotton residue on the connector.

Repeat at least three times.

Use the cotton tipped applicator dipped in alcohol to remove any grease and dirt near the connector area.

Use a dry cotton tipped applicator and repeat steps 3 through 5.

Spray compressed air on the connector area by pointing the tube/nozzle about ½ inch away from the surface.

CAUTION : Do not point nozzle at yourself and others, ensure the nozzle or tube is away from your face.

Spray compressed air in the connector area by pointing the tube/nozzle about ½ inch away from the surface.

CAUTION

: Do not point nozzle at yourself and others, ensure the nozzle or tube is pointed away from your face.

8.

Ensure that there is no lint left by the cotton tipped applicator, remove lint if found.

If grease and other dirt can be found on other areas of the cradle, use lint free cloth and alcohol to remove.

Allow at least 10 to 30 minutes (depending on ambient temperature and humidity) for the alcohol to air dry before applying power to cradle.

If the temperature is low and humidity is high, longer drying time is required. Warm temperature and dry humidity requires less drying time.

Cleaning Frequency

The cleaning frequency is up to the customer’s discretion due to the varied environments in which the device units 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.

Cleaning the Wrist Mount

It may be necessary to wash the wrist mount strap and replaceable comfort pad when they become soiled.
