Chapter 5 Maintenance and T oubleshooting

Introduction

This chapter includes instructions on cleaning and stor g the mob le computer, and provides troubleshooting solutions for potential problems during mobile computer operat on.

Maintaining the Mobile Computer

For trouble-free service, observe the fo ow ng t ps when using the mobile computer:

For trouble-free service, observe the fo ow ng t ps when using the MC31XX:

• Preliminaryrotect 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 scratch the scr		n of the MC31XX. When working with the MC31XX, use the supplied stylus or
plastic-tipp	d p ns int	nd d for use with a touch-sensitive screen. Never use an actual pen or pencil or other
sharp object on the su face of the MC31XX screen.
Moto ola	comm nds using a scr n protector, p/n KT-122010-01R.
• The touch-s nsitive sc		n of the MC31XX is glass. Do not to drop the MC31XX or subject it to strong
impact.

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

• Use 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

• 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

• nearPreliminaryradiator or other heat source. Do not place battery into a microwave oven or dryer. Battery usage by children should be supervised.

• Quick and easy installation.

Battery Safety Guidelines

•	The area in which the units are charged should be clear of debris nd combustible materials or chemicals.
	Particular care should be taken where the device is charged in		non comme ci l envi onment.
•	Follow battery usage, storage, and charging guideli es fou d in the user's guide.
•	Improper battery use may result in a fire, explos o	, or other h z	rd.
•	To charge the mobile device battery, the battery a	d 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 ncompatible 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 Enterpr se Mob l ty 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 co p eted the USB-IF co pliance 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 f t any battery without checking it has the Motorola authentication hologram.

• Do not disass mble or op n, crush, bend or deform, puncture, or shred.

• Seve e impact f om d opping any battery-operated device on a hard surface could cause the battery to

overheat.

• Do not sho t ci cuit a batte y 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

• 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.

Maintenance and Troubleshooting 5 - 3

Cleaning

CAUTION Always wear eye protection.

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

Preliminary! If you have to use any other solution for medical reasons please contact Motorola 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 acco dance with these guidelines.

Materials Required

• Alcohol wipes

• Lens tissue

• Cotton tipped applicators

• Isopropyl alcohol

• Can of compressed air with a tube.

Cleaning the MC31XX

Housing

Using the alcohol wipes, wipe the hous ng nc ud ng keys and in-between keys.

Display

The display can be wip d down with the alcohol wipes, but care should be taken not to allow any pooling of liquid around the edges of the display. Imm diately 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 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

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.	Preliminary
	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			pplic tor.
5.	Spray compressed air in the connector area by poi ti g the tube/		ozzle	bout ½ inch away from the surface.
	CAUTION: do not point nozzle at yourself and others, e sure the		ozzle or tube is pointed away from your
	face.
6.	Ensure that there is no lint left by the cotton t pped appl cator, remove li			t if found.
7.	If grease and other dirt can be found on other areas of the cradle, use li			t free cloth and alcohol to remove.
8.	Allow at least 10 to 30 minutes (depending on a bient te perature and humidity) for the alcohol to air dry
	before applying power to cradle.
	If the temperature is low and hu	d ty s h gh, longer drying time is required. Warm temperature and dry
	humidity requires less dry ng t	e.

Cleaning Frequ ncy

The cleaning f equ ncy is up to the customer’s discretion due to the varied environments in which the mobile

devices are used. Th	may be cl	an d as frequently as required. However when used in dirty environments it
may be advisable to p	iodically cl	an the scanner exit window to ensure optimum scanning performance.
