Thank you for choosing the WORKABOUT PRO. You’ve pur­chased a flexible hand-held computer with a wide range of options
that make configuring and upgrading the unit fast and easy, enabling
you to meet your changing needs now and in the future.

1. Basic Preparation

Thank you for choosing the WORKABOUT PRO.You’ve purchased
a hand-held with a wide range of options to help you tailor the unit to
meet your exact requirements now and in the future.

Your WORKABOUT will provide many years of productive use.

Important:

All approval and safety information is outlined in the
‘WORKABOUT PRO C, M-E & S Regulatory & Warranty
Guide’, PN 8000084. It is important that you review all
safety guidelines before charging a battery or operating
a scanner.

This quick start guide provides basic information on the operation
and features of the Psion Teklogix WORKABOUT PRO S Hand­Held Computer. For more detailed information, refer to the WORK-
ABOUT PRO M-E, C & S Hand-Held Computer User Manual or the
documentation supplied with the application you are using.

Typically, WORKABOUT PRO S hand-helds are configured at the
factory and arrive ready for use.

1.1 Charging The Battery

Batteries shipped from the factory are not charged. They must be
fully charged prior to use. Full capacity may not be reached until at
least 5 full charge/discharge cycles have been performed.

Keep in mind also that, along with the main battery, the WORKA­BOUT PRO S is equipped with an internal, backup battery that pre­serves data stored on the unit while the main battery is swapped.

Important:

Psion Teklogix WORKABOUT PRO S Hand-Held Computer Quick Reference Guide 3

The backup battery is trickle charged from the main battery.
To maximize battery life, avoid excessive discharging and

recharging of the backup battery by keeping the main
battery fully charged.

IF YOU ARE POWERING UP A NEW UNIT, a warning
message may appear on the screen indicating that the
backup battery capacity is low. To recharge the backup bat­tery, you must fully charge the WORKABOUT PRO with
the main battery installed in the unit. An overnight charge is
recommended.

1.2 Installing The Battery

• Turn the fasteners at the base of the battery cover counter­clockwise to unlock the cover and remove it. The top of the
stylus is shaped to help you loosen the fasteners.

• Insert the charged battery. Replace the battery cover, and turn
the fasteners at the base of the battery cover clockwise to lock
the battery in place.

Note: If you are using a docking station, you can insert an

uncharged battery, dock the unit and switch it on.

1.3 Switching The Unit On

• Press and hold down the [ENTER/ON] key for at least
one second to switch the unit on.

• When the LED flashes green, release [ENTER/ON].

The startup desktop is displayed.

Note: If the unit was already in use – the unit may be off (suspend

state) – pressing [ENTER/ON] ‘wakes’ the unit from this
state. The screen in which you were working prior to the sus­pend state is displayed.

1.4 Switching The Unit Off (Suspend)

• Press the [FN/BLUE] key, and then press [ENTER/ON] to
switch off the WORKABOUT PRO S.

Psion Teklogix WORKABOUT PRO S Hand-Held Computer Quick Reference Guide 7

ALPHA/

Orange Key

The keyboard is equipped with a set of standard keys along with a
[ALPHA/ORANGE] and a [FN/BLUE] modifier key to provide
access to additional keys and system functions. These extra keys are
colour coded in orange and blue print above the standard keys.

2.2.1 Modifier Keys

The [CTRL], [ALT], [ALPHA/ORANGE] and [FN/BLUE] keys are
modifier keys. Pressing a modifier key changes the function of the
next key pressed. For example, alpha keys are displayed in orange
print above the numeric key [1]. Pressing the [ALPHA/ORANGE]
key followed by the [1] key displays the letter a rather than the
number 1.

The [CTRL] and [ALT] keys operate much like a desktop keyboard
except that they are not chorded – two keys cannot be held down
simultaneously. The modifier key must be pressed first followed by
the key whose function you want modified.

Activating Modifier Keys

When a modifier key is pressed once, the modifier key icon displays the
key in lowercase letters in the taskbar. For example, pressing [CTRL]
once displays ctrl key in the taskbar. Once the next key is pressed, the
modifier key becomes inactive and disappears from the taskbar.

Locking Modifier Keys

When a modifier key is pressed twice, it is ‘locked’ on. A ‘locked’
modifier key icon displays the key in uppercase letters in the taskbar.
For example, pressing the [FN/BLUE] key twice locks it on – it is
displayed as BLUE KEY in the taskbar at the bottom of the screen. The
locked modifier key remains active until it is pressed a third time to
unlock or turn it off.

entered key stroke.

[DEL] key ([FN/BLUE] [BKSP]) erases the character at the cur-

sor position.

The [CTRL] And [ALT] Key

Modify the function of the next key pressed and are application

dependent.

The [TAB] Key

Usually moves the cursor to the next field to the right or down-

ward. Pressing [ALPHA/ORANGE] [TAB] move the cursor
backward.

The [ESC] Key

Generally used as a keyboard shortcut to close the current menu,

dialog box or activity and return to the previous one.

Psion Teklogix WORKABOUT PRO S Hand-Held Computer Quick Reference Guide 9

The [SPACE] Key

Inserts a blank space between characters. In a Windows dialog

box, the [SPACE] key enables (√) or disables a checkbox. This
key is accessed by pressing [ALPHA/ORANGE] followed by the
numeric key [0].

The [SCAN] Keys

Activate the scanner beam while pressed. For units without inter-

nal scanners, these keys are inoperable.

The Function Keys – [F1] to [F4]

[FN/BLUE] followed by the appropriate numeric key to access a
function key. These keys are provided to support user applica­tions that require [F] keys.

4. General Maintenance

4.1 Caring For The Touchscreen

The touchscreen can be permanently damaged by harsh chemicals and
is susceptible to abrasions and scratches. Using sharp objects on the
touchscreen can scratch or cut the plastic or crack the internal conduc­tive coating. Protect the touchscreen from the following chemicals:

• mustard, ketchup,

• sodium hydroxide,

• concentrated caustic solutions,

• benzyl alcohol, and

• concentrated acids.

If touchscreens are used in harsh environments, apply disposable
screen protectors to dramatically extend the life of the touchscreen.

4.2 Cleaning The WORKABOUT PRO S

Important: Do not immerse the unit in water. Dampen a soft cloth with

mild detergent to wipe the unit clean.

•Use only mild detergent or soapy water to clean the unit.

• Avoid abrasive cleaners, solvents or strong chemicals. The
plastic case is susceptible to harsh chemicals. The plastic is
partially soluble in oils, mineral spirits and gasoline. The
plastic slowly decomposes in strong alkaline solutions.

• To clean ink marks from the keypad and touchscreen, use
isopropyl alcohol.
