M90 PDE Unit

""""""""""""""""""""""""""""

INTERMECRhand-held terminals are used in a variety of
applications throughout the world whenever data needs to
be collected.

Introduction

The M90 Portable Data Entry (PDE) Unit is one of the
most versatile and flexible data collection devices available
today.

Your M90 PDE unit comes with sufficient memory for most
data collection applications with added features to ensure
data storage integrity, barcode scanning, and communica­tion options.

Intermec International Inc. of Intermec Technologies Corpo­ration hopes that this manual will help you get acquainted
with the M90 features and allow you maximum productiv­ity and satisfaction from us ing this unit.

General

The M90 PDE unit allows you to enter data with the key­board or integrated barcode scanner. Pen and paper are
now redundant. The stored data is later transferred to your
host computer either directly via a cable or over the tele­phone network via a modem.

M90 Series Portable Data Entry Unit User’s Guide 1

M90 PDE Unit

Customized Version

Your M90 PDE unit has more than likely been adapted to
suit your specific requirements. This has been achieved by
programming your unit with your special version of the
M90 program. The functions described in this manual can
therefore vary from your customized version. For details,
refer to separate instructions supplied by your System Part­ner.

M90 PDE Unit

Start Up of New M90 PDE Unit

Before you can use the M90 PDE unit after unpacking it,
you must do two things:

1. Insert the main batteries and wait for the prompt to
appear in the “Ready” mode.

2. Start the internal program by loading an application
program from a host computer.

"

NOTE: It is only necessary to follow these steps once after taking delivery of

the M90. If your M90 is delivered with inserted batteries and applica­tion program these procedures normally do not apply.

On the next two pages are instructions for r eplacing either
the main battery or the backup battery. Have the M90

Main Battery Replacement

1. Slide tab from right to left (see Figure 1-1).

2. Slide the main battery pack down and out from the
battery compartment.

3. Insert the new main battery pack up into the battery
compartment.

4. Slide the tab from left to right to secure the battery.

Backup Battery Replacement

"

NOTE: The main battery must remain in place during replacement of the

backup battery, otherwise the data in the RAM will be lost.

1. Unscrew and remove the backup battery cover with a
Phillips screwdriver, then carefully remove the old
lithium battery.

2. Insert a new lithium battery into the holder. Be sure
to align the “+” symbol on the lithium battery with the
screw hole in t he M90 (see Figure 1-2).

3. Securely tighten the backup battery cover back onto
the M90.

Battery Replacement

Replacing Main Battery

Replace alkaline batteries when the M90 PDE unit dis­plays:

! WARNING !
MAIN BATTERY
VOLTAGE LOW

or if you s ee small battery icons to the right of the display.
These indicate t hat the main battery should be replaced
within approximately one hour, otherwise, the keyboard
will be set in the “Off” position (see page 15). These warn­ing will periodically repeat until the battery is replaced.

If the main battery is not replaced, the M90 will be Off and
if the backup battery is at its full capacity, the data w ill be
safe for two years. If, however, the backup battery is low
on power, the data will remain safe for three weeks.

M90 PDE Unit

If you are using a rechargeable battery, the M90 will have
to be charged for approximately half an hour after the bat­tery low warning occurs. See page 22 for details.

WARNING: Data will be lost if the main battery is exhausted and the

backup battery is too low.

Replacing Backup Battery

Replace the lithium backup battery if the M90 displays the
following message. See page 6 for details.

Dock

A connection box that charges the M90 while connected to a
modem or a host computer. Each dock holds one M90. The
docks are powered by an external wall charger supplied
with the unit. Each dock has a spare battery charger.

Using the Dock

To use the dock, connect the charger and the wall socket.
Then, slide the M90 into the dock. The LED marked
“Charge” should turn solid RED, if rechargeable batteries
are being used. The Charge LED will turn solid GREEN
when the batteries are over 80 percent full. The unit is now
ready for use.

The spare battery will start changing only when the unit
battery is fully-charged, or there is no unit in the dock. It
will take four hours to fully charge the battery in the M 90,
and then an additional four hours to charge the spare bat­tery.

M90 PDE Unit

Vehicle Dock

A connection box, in a vehicle, that charges the M90 PDE
unit while connected to a modem or a host computer. Each
vehicle dock holds one M90. The vehicle docks can be pow­ered by the vehicle battery via a power cable.

Using the Dock

To put the M90 in the vehicle dock , enter it with the top
section first so that the hooks of the vehicle dock grip
around the rubber grommet at the top of the M90. Then,
push the bottom end of the M90 forward so that it will slide
into the vehicle dock. The dock provides power and regular
charging.

Battery Pack Charging

When the M90 shows the “Main battery low” message or
icons, the battery pack in the M90 needs to be recharged.
There are two ways to charge the battery: regular and
quick charging.

M90 PDE Unit

Regular Battery Charging

Plug one end of a 9-volt DC power adapter into the DC-jack
of the M90 PC Cable (P/N: M90402) and the other end into
an ac wall outlet. The battery pack will be fully recharged
after 14–16 hours.

The dock also has a pocket for charging a spare battery
pack. To charge a battery pack, put the spare battery in
the battery pocket of the dock. The battery will be fully
charged in four hours providing that there is no M90 PDE
unit in the dock. If an M90 is in the dock, the spare battery
does not start charging until the battery within the M90 is
fully charged (as in Figure 1-4).

When the spare battery is waiting for the battery in the
M90 to be charged, the charge LED for the spare battery
flashes red. When charging starts, the LED changes to a
solid red. The LED changes to a solid green when the spare
battery is fully charged.

The act of moving data records from the M90 PDE unit to a
host computer or printer. During transfer, the M90 sends
the entered data via a communication link to the host
computer. After transfer, the entered data is retained
unaltered by the M90. This is to allow a second transfer to
take place if the first was unsuccessful.
