Introduction

The Allegro CE/DOS Field PC is designed to
meet the needs of a user collecting data with a
hand-held computer in a rugged field
environment. This section of the manual
describes the unique hardware components of
the Allegro, including the case, keyboard,
display, communication ports, batteries, PC
card slot, and expansion pods.

Some hardware and software features are only
functional within one operating system. For
example, the touchscreen is used to operate
Windows CE; it is not operational when you are
in DOS. Conversely, the display panning
features only apply to operation while in DOS.

Throughout the manual, one of the following
symbols is shown next to the description of the
features that are unique to one operating
system:

➫ WIN cE
➫ DOS

If one of these symbols is not shown, the feature is functional for both
operating systems.

Case Features

▲▲

The case has the following features:
❏ The polycarbonate ABS material is rugged, shock resistant, and

formulated to resist damage from chemicals.

❏ The ergonomic shape and smooth edges make it

easy to hold, maximizing comfort and usability in
the field.

❏ The weight distribution is balanced.
❏ There are three gaskets used to seal the case from

water and dust:

- between the top and bottom case halves

- around the battery compartment

- around the PC card slot compartment
In most circumstances, these gaskets are not field

replaceable. Contact our Service Department if a
gasket needs to be replaced.

❏ There are two doors: one for the battery

compartment and one for the PC card slot. These doors are user­replaceable. Contact our Sales Department for ordering information.

There are four metal cleats, one on each corner of the Allegro case. Each
cleat has two metal rings that are used to attach the hand strap and
shoulder strap onto the Allegro.

The straps can be attached in numerous configurations, depending on
your preference and whether you are right-handed or left-handed. The
shoulder strap can be used as a neck strap for hands-free operation. The
tension on the hand strap is adjustable.

Special Keys and Key Sequences

▲▲

The standard keyboard letters, numbers, and functions are printed in
dark brown on the off-white keys and in off-white on the dark brown
keys. These standard options are operational unless a GOLD or BLUE
shift key is pressed.

Blue Shift Key Usage

To access the keyboard characters printed in blue, press and release the
BLUE shift key followed by the key with the desired blue-lettered
character. To activate several blue-lettered keys before returning to
standard mode, continue to hold the BLUE shift key down while you
press the desired keys. Once the BLUE shift key is released, the
keyboard reverts back to the standard mode.

Gold Shift Key Usage

To access the gold shift key options, press and release the GOLD shift
key followed by the key with the desired gold symbol. To activate
several gold-lettered options before returning to standard mode,
continue to hold the GOLD shift key down while you press the desired
keys. Once the GOLD shift key is released, the keyboard reverts back to
the standard mode.

Circular Key Usage

The circular key located in the center of the keyboard has three
functions:

1) Standard (no shift keys): Up, Down, Right, and Left arrow keys

2) BLUE shifted functions: Page Up, Page Down, Home, and End

3) GOLD shifted functions ë DOS: Pan the display Up, Down, Right, or
Left

Keyboard Options For Both Windows CE and DOS

The following keys and key sequences are functional in both
Windows CE and DOS.

On/Off (Reset)

This key is used to turn the Allegro on and off. The ridge around the key
helps prevent the Allegro from being accidentally turned on without
your knowledge (while it is in a backpack, for example). Holding down
the On/Off key for about eight seconds performs a hard reset. Release
the key when the reboot process begins.

❖ Note: When you turn the Allegro on or off, there is no "beep." Also, it is
normal for a horizontal line to appear briefly on the screen. When the Allegro is
booting to Windows CE, it takes a minute for the Windows CE Desktop to
appear.

Contrast Keys +
To make the display darker, press the GOLD key and the <F5> key. To
make the display lighter, press the GOLD key and the <F4> key.

Backlight On/Off +
The backlight is toggled on and off by pressing the GOLD key and the
<F3> key.

Tab, Forward and Backward

In a DOS program, the right arrow is a forward tab and the left arrow is
a back tab. In Windows CE the tab keys are used primarily for cursor
movement between fields.

Dirt and debris can get underneath the keyboard bezel. To clean it, use a
coin to pull the bezel up at the recess located at the bottom of the
keyboard and remove it. We recommend that you use warm water, mild
detergent, and a toothbrush to clean the keyboard or simply brush it
out. The Allegro remains sealed during this process. (Do not direct a
high pressure stream of water at the keyboard to clean it. This action
could break the seal, causing water to get inside the Allegro.)

Reattach the bezel by carefully inserting the top ridge under the
function keys and lowering the bezel down flat onto the case. Press
down along the sides while aligning the keys through the holes.

❖ Important Note: After you reattach the bezel, check each key to make sure it
is completely free from the bezel. If any part of a key is caught underneath the
bezel, you may not be able to turn the Allegro on or you may hear a continuous
string of beeps.
