Magnetic Stripe Reader (MSR)
This section describes how to set up and use the snap-on MSR with the MC75A. The MSR snaps on to the bottom
of the MC75A and removes easily when not in use.
When attached to the MC75A, the MSR allows the MC75A to capture data from magnetic stripe cards. To
download MSR data capture software, visit the Motorola web site at http://www.symbol.com/support.
With the MSR attach, the MC75A can still be charged by placing the MC75A with MSR into a cradle or connecting
to a charging cable.
Attaching and Removing the MSR
To attach, slide the MSR onto the bottom of the MC75A and secure by snapping the arms into the MC75A housing.
Figure 7-11
MSR Installation
To remove the MSR open the arms and pull the MSR from the MC75A.
Using the MSR
Install an MSR enabled application onto the MC75A.
To use the MSR:
1. Attach the MSR to the MC75A.
2. Power on the MC75A.
3. Launch the MSR application.
4. Swipe the magnetic stripe card through the MSR, with the magnetic stripe on the card facing down. Swipe the
card in either direction, from left to right or from right to left. For best results, gently press down on the card
while swiping to ensure contact with the bottom of the reader.

Chapter 8 Maintenance & Troubleshooting
Introduction
This chapter includes instructions on cleaning and storing the MC75A, and provides troubleshooting solutions for
potential problems during MC75A operation.
Maintaining the MC75A
For trouble-free service, observe the following tips when using the MC75A:
•
Do not scratch the screen of the MC75A. When working with the MC75A, 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 MC75A screen.
•
A screen protector, p/n KT-67525-01R, is applied to the MC75A. 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.
•
The touch-sensitive screen of the MC75A is glass. Do not to drop the MC75A or subject it to strong impact.
•
Protect the MC75A 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 MC75A in any location that is dusty, damp, or wet.
•
Use a soft lens cloth to clean the MC75A. If the surface of the MC75A 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.

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)

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.
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 Main Battery on page 1-9.
2. Close battery door.
3. Dip the cotton portion of the cotton tipped applicator in isopropyl alcohol.
4. Rub the cotton portion of the cotton tipped applicator back-and-forth across the connector on the bottom of the
MC75A. Do not leave any cotton residue on the connector.
5. Repeat at least three times.
6. Use the cotton tipped applicator dipped in alcohol to remove any grease and dirt near the connector area.
7. Use a dry cotton tipped applicator and repeat steps 4 through 6.
8. Spray compressed air on the connector area by pointing the tube/nozzle about ½ inch away from the surface.
9. 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.
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.
CAUTION Do not point nozzle at yourself and others, ensure the nozzle or tube is away from your face.

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.

Battery is low. If the scanner stops emitting a laser beam upon a trigger press,
check the battery level. When the battery is low, the scanner shuts

When trying to
connect a Bluetooth
phone and MC75A,
the phone thinks a
previously paired
MC75A is used.
The phone
remembers the
name and address
of the MC75A it last
paired with via the
Bluetooth radio.
Manually delete the pairing device and name from the phone. Refer
to the phone’s user documentation for instructions.
There is a delay in the
Bluetooth stack
re-initializing during a
resume from
suspend.
This is normal
behavior. No solution required.
The Bluetooth
connection drops. The MC75A
suspends and the
Bluetooth radio
power turns off.
When the MC75A suspends the Bluetooth connection is dropped.
Re-connect the Bluetooth connection when the MC75A returns from
