Chapter 5 Maintenance and Troubleshooting

Preliminary

Introduction

This chapter includes instructions on cleaning and storing the mobile computer, and provides troubleshooting solutions for potential problems during mobile computer operation.

Maintaining the Mobile Computer

For trouble-free service, observe the following tips when using the mobile computer: For trouble-free service, observe the following tips when using the MC31XX:

•

Do not scratch the screen of the MC31XX. When working with the MC31XX, use the supplied stylus or

plastic-tipped pens intended for use with a touch-sensitive screen. Never use an actual pen or pencil or other

sharp object on the surface of the MC31XX screen.

Motorola recommends using a screen protector, p/n KT-122010-01R.

•

The touch-sensitive screen of the MC31XX is glass. Do not to drop the MC31XX or subject it to strong

impact.

•

Protect the MC31XX from temperature extremes. Do not leave it on the dashboard of a car on a hot day, and

keep it away from heat sources.

•

Do not store or use the MC31XX in any location that is dusty, damp, or wet.

•

Use a soft lens cloth to clean the MC31XX. If the surface of the MC31XX screen becomes soiled, clean it

with a soft cloth moistened with a diluted window-cleaning solution.

•

Periodically replace the rechargeable battery to ensure maximum battery life and product performance.

Battery life depends on individual usage patterns.

5 - 2 MC31XX Series Mobile Computer User Guide

Preliminary

•

A screen protector is applied to the MC31XX. Motorola recommends using this to minimize wear and tear.

Screen protectors enhance the usability and durability of touch screen displays. Benefits include:

• Protection from scratches and gouges

• Durable writing and touch surface with tactile feel

• Abrasion and chemical resistance

• Glare reduction

• Keeping the device’s screen looking new

• Quick and easy installation.

Battery Safety Guidelines

•

The area in which the 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.

•

Follow battery usage, storage, and charging guidelines found in the user's 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 ºF and

+104 ºF (0 ºC and +40 ºC)

•

Do not use incompatible batteries and chargers. Use of an incompatible battery or charger may present a risk

of fire, explosion, leakage, or other hazard. If you have any questions about the compatibility of a battery or a

charger, contact Motorola Enterprise Mobility support.

•

For devices that utilize a USB port as a charging source, the device shall only be connected to products that

bear the USB-IF logo or have completed the USB-IF compliance program.

•

To enable authentication of an approved battery, as required by IEEE1725 clause 10.2.1, all batteries will

carry a Motorola hologram. Do not fit any battery without checking it has the Motorola authentication

hologram.

•

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.

•

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 properly dispose of used re-chargeable batteries.

•

Do not dispose of batteries in fire.

•

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, contact Motorola Enterprise Mobility support to arrange

for inspection.

Cleaning the MC31XX

Housing

Using the alcohol wipes, wipe the housing including keys and in-between keys.

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 dry the display with a soft, non-abrasive cloth to prevent streaking.

Scanner 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. Remove the main battery from mobile computer. See Replacing the Battery on page 1-8.

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 on the bottom of the

MC31XX. 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.

5 - 4 MC31XX Series Mobile Computer User Guide

Preliminary

7. 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.

8. Inspect the area for any grease or dirt, repeat if required.

Cleaning Cradle Connectors

To clean the connectors on a cradle:

1. Remove the DC power cable from the cradle.

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

3. Rub the cotton portion of the cotton tipped applicator along the pins of the connector. Slowly move the

applicator back-and-forth from one side of the connector to the other. Do not let any cotton residue on the connector.

4. All sides of the connector should also be rubbed with the cotton tipped applicator.

5. 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.

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

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

8. 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 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.
