The fex21 case Is built utilising the latest plastics technology to ensure the
optimum ruggedness for the case style. Utilising High impact Polycarbonate
ABS, also known as Impact Modified Plastic, the fex21 is built to withstand harsh
working conditions whilst retaining the weight advantage that modern plastics
technology offers.
Sealing
Sealed to the internationally recognised environmental standard IP65, the tex21
is designed to withstand water ingress as a result of driving rain over sustained
periods. This Is achieved through a total of nine water resistant rubber seals
around the case
Temperatures
The fex21 is designed to work through a wide range of temperatures in line with
it’s rugged capabilities. For the mono unit the operating temperature ranges from
-10°C to +50°C. For the colour screen this range changes to 0°C to +40°C.
The storage temperatures for all devices range from -20°C to +60°C.

Serial Label
The fex21 serial label contains three main pieces of information, Serial Number,
Configuration String and model number.
Serial Number
The serial number is the ten digit number on the unit. This number will be
unique to the device on which it Is placed.
Model Number
The model number signifies which particular subset of fex21 build the unIt
belongs to. This number is utilised withIn the Husky factory to denote
required build components or by the customer to re-order identical units.
Configuration String
The configuration string gives a brief coded overview of the machine build
configuration. When talking to customers it will be this information that will
be of most use to the engineer. This will tell the engineer exactly what
components the unit contains.
The following is an example of an fex21 configuration string:
70-MONI092MHZ/16MBINO-CFN34US/16FLS
This gives us the following information:
70-MON = Mono fex21 model 70-
092MHZ = 92 MHz processor
16MB = 16MB RAM
NO-CF = No compact flash fitted in factory
V34US = V34 United States approved modem
16FLS = 16 MB flash (Operating System storage only)

Display
The fex21 has three display options, STN, TRN and Mono. Each of these screen
types are suited to specific conditions and uses.
STN
The STN screen is the standard colour transmissive screen. This screen
provides the best colour option for Indoor use as It is both bright and easily
visible indoors. However this screen suffers significant degradation for
outdoor use. This screen option is not recommended If the unit is to be
used outdoors or in direct sunlight.
TFiN
The Transflective screen utilises the latest display technology to provide
the optimum visibility in both indoor and outdoor conditions. if a colour
screen is required for outdoor use then this would be the recommended
solution.
Mono
The fex21 monochrome screen is the ideal choice tor indoor/outdoor use
when colour is not an issue to the software. This option offers a 16-
greyscale display and has good visibility both indoors and outdoors.
All screens are 6.5“ ‘A VGA 640x240 LCD with integral backlight. The STN
screen requires the backlight to be active at all times (When powered up) but
does allow stepped dimming. Mono and Transflective screens can both be used
without backlight therefore offering Improved power consumption.

The fex21 incorporates a battery-charging indicator situated behind the IrDA
window. This red LED Indicates the state of charging in the following ways:
0 LED off: AC Adapter not connected or AC adapter not switched on
0 LED On: The unIt Is running on AC adapter power. This state also indicates
that charging is complete, disabled or not allowed (battery too hot/cold, or no
rechargeable battery fitted).
- Slow regular flashing (once per second): The unit is running on AC power and
the battery is charging.
0 Fast irregular flashing: The unit Is running on AC adapter power. Battery
charging has not started or has been aborted. This may be indicative of a
battery fault or that a battery has over-heated. Please refer to the battery
section in the trouble-shooting guide for further details.

Microphone
The fex21 has a built in microphone, as indicated above by a small opening just
below and to the right of the erA window. This can be used to record and store
sound such as spoken dictation utilising the Windows CE voice recorder. The
recordings can be stored in either Mobile Voice or PCM formats and in a variety
of different sample rates. Optimum sound quality can be achieved by recording
in PCM format at a sample rate of 11,025Hz. This can be altered in the
Recording Format option under the Tools menu within the Microsoft Voice

Batteries
Location and Housing
The fex21 battery is located in the back of the unit lying parallel to the
primary COM port (COM1). The battery can be removed by pulling the
two small catches forward until they click open. Please note that the
stylus must be removed from its housing before attempting to remove the
battery
About the Battery
The fex21 is designed for use with either a rechargeable NiMH battery
pack or 4 AA-slze alkaline cells. Both types are contained within a
specially designed battery holder. The fex21 is supplied as standard with
a rechargeable battery. The alkaline battery holder is available as an
optional extra upon request from ltronix (UK).
Use of non-rechargeable alkaline batteries is only recommended as an
emergency measure. The quality of alkaline cells cannot be guaranteed,
as they are not supplied by ltronix (UK).
in addition to the main NIMH battery the tex21 has a built in rechargeable
backup battery. This internal cell is used to retain the contents of the unit
RAM in the event of complete power loss from the main cell. This backup
battery will retain the RAM contents of the unIt for up to 72 hours
(depending upon charge state). This backup cell also allows the user to
safely swap the main cell without compromising the machine data
integrity.

Keyboard
The fex21 keyboard is made up of 67 hardened rubber keys. The keys are
arranged in colour coded groupings and Incorporate a separate numeric keypad.
The keyboard can currently be supplied in the following language variants:
UK/US
Swedish
French
German
Danish
Spanish
There is also a membrane keyboard option available upon request.
Special Keys
In addition to the standard keys normally available on an HP/C keyboard the
fex21 has an added function key, the PAW key. This extra key Is located Just to
the left of the numeric keypad next to the number 1. The PAW key allows access
to extra key options printed on the keyboard overlay. The extra keys provided
vary depending upon the country specifications of the unit.
To access the extra characters It Is necessary to hold down the PAW key in
combination with other keys on the keyboard. On the UK/US keyboard for
example, to access the ‘#' key it is necessary to hold down the PAW+P keys.
These keys can also be used in conjunction with the SHIFT key to produce
further combinations. Again on the UK/US keyboard holding down the
PAW+SHIFT+P keys will produce the ‘-' key.
Many international languages require the use of accents in conjunction with
specific letters. The fex21 also caters for these options by use of what are
known as ‘Dead Keys'. Use of a dead key In isolation will not produce a character
output but will provide an accent In conjunction with the next key pressed.

Power Key
The power key is located at the top centre of the keyboard. This key performs
two main functions, it turns the unit power on and off and also forms part of the
unit reset function.
When the fex21 is first powered on after having a new battery fitted the power
key will need to be pressed twlce In order to start the unit.
Contrast Keys
The two contrast keys are located to the left of the power key. One is marked
with a '+' symbol and the other with a '-‘ symbol. To increase the screen contrast
press the key marked '+' and to decrease the contrast press the key marked '-'.
The fex21 also has a default contrast setting that the unit can be reset to at any
time. To attain the default contrast setting, press both contrast keys at the same
time.
Backllght Keys
To the right of the power key are the two backlight keys, again marked ‘+' and ‘-'.
These keys have slightly differing functions depending on the screen
configuration of the unit,
On a mono fex21 the backlight keys simply turn the EL backlight on and off. To
power on the EL backlight press the '+‘ key and to power it off press the '-' key,
The Transmissive colour fex21 screen, (STN), requires the backlight to be active
at all times, In this instance the backlight keys reduce and Increase the Intensity
of the CCFL backllght. To increase the Intensity of the backlight press the ‘+‘ key
and to reduce the intensity press the ‘-' key. Note that the brighter the backlight
intensity the more power the unit consumes. it is recommended that the
backlight be reduced to the minimum comfortable intensity in order to maximise
battery llfe.
The Transflectlve colour fex21 screen, (T RN), does not require the backlight to
be powered at all times. As with the transmissive screen the backlight keys can
be used to Increase and decrease the backlight Intensity but will also power the
backlight on and off at the extremes of adjustment.

Numeric Keypad
Unlike many other Windows CE devices the fex21 is also equipped with a
separate numeric keypad. This colour coded keypad section is located on the
right hand side of the keyboard and is arranged in much the same way as a
standard PC keyboard keypad.
A standard H/PC unit has the numeric keys placed along the top row of the
keyboard. It was decided early in the development of the fex21 that this
configuration would probably be unacceptable to most of the traditional Husky
users. The majority of Husky unlts are used for field data collection, a task that
traditionally requires large quantities of numeric data input. Most users have
become accustomed to the standard numeric keypad layout and Husky have
always provided this keyboard deslgn. It Is for this reason that the tex21 has the
numeric keys implemented in a separate colour coded keyspace within the
keyboard design.
Version 1.00 20 24/08/00
@rrnomx° mas-«553621
Touch Screen
The fex21 is primarily designed to maximise the use of the touch screen
technology. The screen itself is a 6.5" VGA 640x240Aplxel LCD display utilising
the latest resistive touch screen technology. The screen is made using a glass
plate covered with a layer of Mylar separated by a small gap. Each of these
components contains one half of a resistive grid. When pressure is applied to
the top layer of the grid it moves to touch the bottom layer therefore creating a
point of altered resistance. This point is interpreted as a grid position and is used
by the fex21 to determine where the user has tapped the screen. The 0/8
Interprets this grid position in the same way that a mouse click would be
interpreted by a desktop PC application.
The use of a resistive screen enables the pointing system to be much simpler.
Previous touch screen devices required the use of an active pen specific the
system being used. This could cause problems In the field if the pen was lost or
the pen batteries became drained. WIth the resistive technology the user can
simply substitute their finger for the stylus if required.
Stylus
The fex21 stylus is designed to be easy to use, lightweight and gentle on the
touch screen. it is stored in a channel placed along the length of the battery
tube.
The stylus tip is made of a soft material and spring loaded to avoid excessive
wear on the screen coating. As the touchscreen requires a point contact, your
fingernail can be used in place of a lost or damaged stylus. Hard or metal tipped
objects such as ballpoint pens should not be used as this may scratch or damage
the touch screen. A replacement pen can be ordered from itronix (UK) it
required.
Note on Stylus Location
As previously mentioned the tex21 stylus can be stored in a specially cut channel
that runs the length of the battery pack. Before attempting to remove the battery
the stylus must be removed from It's housing. Attempting to remove the battery
pack while a pen is fitted may result in damage to the battery pack, fex21 case
and pen.

Operating System
The current fex21 operating system ls Windows CE Handheld PC Edition Version
3.01. This version Includes Pocket Internet Explorer Version 3.01 and Pocket
Outlook Version 3.01.
Windows CE is a processor dependent operating system and as such requires
care when selecting ore-written software. The lex21 system Is built around a
Toshiba FISOOO family MIPS RISC processor. When selecting software the user
must look for packages written specifically for this processor type. This Is not
usually a problem as this processor family is one of the most popular with the
majority of H/PC software being available for this hardware platform.

Bundled Applications
In addition to the standard operating system functionality the fex21 also includes
a bundle of Microsoft Pocket Office applications:
Pocket Word v3.01
Pocket Excel v3.01
Pocket Access v3.01
Pocket PowerPoint v3.01
Together these applications form a formidable mobile office solution for the Sales
Rep or mobile engineers.
‘ Meson Podcet Excel 13.01
mesons Pocket powerpointe v3.01
. musqtm Peder Access v3.01
These apps are bundled as part of the operating system build in ROM. In the
event of total power loss or hard reset the applications will not be lost or
corrupted. However, any data contained within the applications or stored in the
machines RAM will be lost.
As these applications can be relied upon to always be present on the system any
application can be written to use their functionality. For example database
applications need not be written from the ground up but can be designed to
utilise the pocket Access system already available on the device.
it is beyond the scope of this course to detail the differences between these
applications and their desktop equivalent. Descriptions of these differences can
be found on the Microsoft web site:

Basic System Set-up
When the fex21 is first removed from the box there a few system set-up
procedures that will need to be followed. The following sections cover the basic
fex21 set-up procedure.
Fitting the Battery Pack
If your fex21 is supplied for use with Alkaline
batterles then they will need to be fitted into
the battery pack - you should insert four AA
size alkaline cells into the battery holder,
taking care that the polarity of each Is correct.
If in doubt check the label fitted to the battery
holder.
Rechargeable NiMH (Nickel Metal Hydride)
batteries, if supplied, are in a sealed pack ;
ready to be fitted to the unIt.
To fit either battery pack, slot the battery pack into the fex21 by locating the two
small lugs in the side of the device and pressing the battery pack firmly in place
until the two small catches click into position.
Powering the unit on for the first time
After fitting the battery, press the power key, located at the top centre of the
keyboard, TWICE to power the unit on. The fex21 screen will be blank during the
first few seconds of power up, to check if the unit ls powerlng up press the
backlight plus key once. If the backlight comes on the unit Is powering up.
Note
The power key will need to be pressed twice to activate the unit only after total
power loss or after inserting the battery after a long absence.
It may take a few seconds before the screen displays data, however this is
normal. To power the unit off again simply press the power key once.
It may also be necessary to place the unit on external power as the battery may
have discharged completely during transit.
If the unit falls to power up refer to the trouble shooting section of this document
for reset procedures.

The Timeout Resume mode determines under what conditions the backlight is
allowed to timeout.
When set to backlight timeout always allowed the backlight will time-out after the
specified period regardless of keyboard or pen activity. The time-out timer will
not be reset after a system event.
If the system is set to ‘Backlight time-out when no keyboard/pen activity‘ then the
backlight will reset It's backlight time-out clock each time a key Is pressed or the
screen is tapped. This effectively means that if the unit is being constantly used
the backlight will not time-cut.
When set to ‘Backlight time-out when no keyboard/pen activity+resume on
activity' the backlight will behave in the same way as the previous option but will
automatically switch back on whenever the screen is tapped or a key is pressed.
The user Is not required to manually power on the backlight with the backlight
key.
The backlight time-out period can be shortened or lengthened by using the scroll
arrows at the side of the control. It is recommended that this time-out period he
as short as possible to conserve battery power. The backlight time-out can be
disabled by reducing the time-out perlod below 30 seconds. This will have the
effect of leaving the backlight on constantly.

tex21 Utll Applet
The fex21 UtiI Applet provides access to the many utilities required to make the
most of the device. This is where the power management and communications
settings can be controlled.
Power
The power tab within the applet allows the user to view the status of the power
system and gain detailed information on how the battery is performing.
Main Battery Level
The Main Battery Level displays the current percentage remaining in the
main power cell. This Is an accurately estimated value based on the time
active since last full charge and takes into account any self discharge of
the cell whilst the device is powered off. The value also accounts for the
battery power consumed maintaining the RAM contents of the unit. If the
system thinks for any reason this value may be inaccurate then there will
be a question mark (7) displayed adjacent to the value. if this happens
then the unit will need to be placed on charge until the value reaches
100%, at this point the gas gauge will be reset and the value will once
more be accurate.
Please note that if the unit has recently been charged to 100% charging
will not restart until the gas gauge value has gone below 96% or for 24
hours after last charge. ThIs feature was introduced Into micro version
9900 and above to prevent damaging charge regimes.

Main Battery Status
The main battery status can display four possible states:
High
Low
Crltlcal
Charging
The HIgh, Low and critical values are taken as a voltage reading from the
battery and further reinforce the main battery level percentage. It is also
from these values that the battery wamlngs are taken.
When the battery is charging an accurate voltage reading cannot be taken
from the battery as it constantly changing so the flag Charglng is used in
it's place.

Charge Remainan
The charge remaining denotes the value in mAh left In the main cell. This
value is calculated in the same way as the charge percentage remaining.
Ac Llne Status
The AC line status denotes whether or not the external charger is
connected to the fex21. This status will read either connected or not
connected.
Enable Charging
Charging can be enabled or disabled by use of this checkbox. When
checked the unit will begin to charge automatically whenever the AC line
is connected to the device. When not checked the unit will not charge
regardless of what the AC line status is.
Allow suspend with Ac adapter connected
if this box is checked then the unit can be powered off by use of the power
key whilst the AC adapter is connected. ThIs ls not allowed by default, as
the fex21 must be powered on in order to charge. Immediately the unit is
powered off the device will cease charging. The device will not suspend
automatically whilst on external power even with this option selected.

This line will tell the user whether the smart battery status is OK or FAILED. if it
reads FAILED then the reason for failure can be displayed in the Diagnostics box
opposite. If the unit is working on external power or contains alkaline cells this
option will display ‘None Fitted’ and the remaining Information will be greyed out.
Serial Number
This value displays the serial number of the battery not the serial number of the
unit into which it is inserted.
Date of Manufacture
This value displays the date the battery was manufactured, (Date format is British
dd-mm-yyyy). This can be useful in determining when the battery is due for
replacement, as can the charge cycles. It is recommended that the battery be
replaced every 18 months or 500 charge cycles, whichever Is sooner.
Chemistry
This displays the battery chemistry in use. Currently this is limited to NiMH only
however other battery types may become available in the future.
Max Capacity
This displays the design capacity in mAh of the battery being used.
Charge Cycles
This value represents the number of times the battery has been charged and
discharged.

Gas Gauge
This value denotes whether the gas gauge is deemed by the system to be OK or
inaccurate. If set to inaccurate then the battery will need to be charged to 100%
In order to reset the gas gauge.
E2PROM 8. E2PROM CBC
These two values denote whether the E2PROM (Smart battery information store)
is working correctly. if either of these values read anything other than OK then
all data from the smart battery may be incorrect. If this happens then the battery
will have to be replaced.
Thermlstor
The fex21 contains a NiMH cell, which it is dangerous to charge at extreme
temperatures. The on board thermistor is the temperature control for charging. If
the thermistor Is set High or Low then this indicates that the thermistor itself is
faulty. In this instance charging will be aborted and will not re-commence. This
failure also means the battery will have to be replaced.
Temperature
This value denotes whether the battery temperature is too low, too high or OK.
The battery will not charge if the temperature value Is set to anything other than
OK due to the danger presented by charging NiMH batteries at temperature
extremes.
The battery will not charge above 52°C or below 0°C
Charging
This line will denote whether charging is OK, failed or aborted. If this is set to
any value than OK then the other information stored within the info screen will
usually point to a reason for failure. There will also be an error code displayed if
charging has failed The codes are interpreted as follows:
0 = Incorrect chemistry (Battery not a NiMH cell therefore the
system will not attempt charging)
Battery Over Temperature (Battery is too hot to safely
charge)
2 = Battery over volts (Battery voltage Is too hIgh. This
indicates a battery failure)
3 = Time out (Battery has not completed charging within the
maximum time limit of 2.5 hours, this code is also an
indication of a battery problem)
If charging Is aborted for any of the above reasons than the aborted flag will
remain in place. The charging flag will not be reset until the charger is removed
and the unit powered off then back on.

Reset Mechanism
The fex21 contains two sets of reset sequences dependent upon the hardware
revision of the unit. There are currently two main revisions in the field, rev05 and
Rev06. The rev05 units are all 75mhz units and rev06 are all 92mhz systems.
The processor clock speed can be determined by Inspecting the configuration
string on the unit serial label. Refer to the serial number section earlier In this
guide for more details on the serial label.
Rev05 and earlier
Warm Reset
To warm reset 3 rev05 device the user is required to hold down the two
contrast keys and the power key for 4-6 seconds. This will reset the
device and close all running applications whilst keeping the RAM contents
intact. The unit should be powered off before attempting a warm reset,
unless the unit cannot be powered off utilising the power key.
Cold Reset
To achieve a cold reset on an older device the user should hold down both
contrast keys and the power key for in excess of 16 seconds. This wlll
reboot the machine, clear the contents of RAM and reset the system to
factory defaults. Any data stored on compact flash will not be affected by
this reset unless a file was open at the time of reset.
Revos and later
Warm Reset
To warm reset a newer device, hold down the two contrast keys only for 4-
6 seconds. Unllke earlier Rev units it is not necessary to power the unit
off to achieve this.
Cold Reset
To cold reset the system, hold down the two contrast keys, the power key
and the backlight plus key for 4-6 seconds.
Both these reset mechanisms will have exactly the same effect on the
devices. The reset key combination has changed only and not the effect.
The above reset mechanisms will provide a solution to a majority of fex21
problems. However, they should only really be used once all other options have
been considered and not as a primary solution.

Communications Problems
Charging Studs
One of the most common communications problems with the fex21 is users
attempting to use charging studs communications without redirecting comms
from the main connector. To redirect ccmms from the main connector to
charging studs the user must navigate to the comms tab of the fex21 Util Applet
and check the charging studs radio button. This will then cut off the oomms
facility of the main 9-way d-type and route all ccm1 serial communications
through the charging studs connector.
You will also notice that this screen also allows the user to redirect port two
output in the same way. As the secondary COM port on the fex21 utilises com4
the IR port has to be disabled and redirected to main connector to allow 9-way
oomms.

Internal Soft Modern
If a user is having problems connecting via the fex21 internal soft modern there
are two main ways to test the unit.
Baslc modem functionality
To test that the modem is attempting to connect, set up a basic termlnal session
on the device using an arbitrary value in the telephone number section.
Select the Emulation tab and in the emulation type drop down list select TTY
(Generlc) then tap 0K.
fimwwx” nus-«55x21
Double tap the icon just created and the terminal screen will open and display the
manual dial screen.
At the prompt type AT then press REI'URN. If the modem is working correctly
the session will return OK after pressing RETURN.
The next test is to attempt to dial out to a physical connection using a PSTN
network. To do this simply connect the Itronix supplied phone cable to the tex21
and a nearby phone socket. Once connected select a simple text based bulletin
board to dial and enter the following command:
ATDT xxxxmxx (Where xxxxxxxx Is the number of the chosen bulletin
board).
Upon successful connection a screen similar to the following will be displayed

If both of these tests work then the internal SoftModem Is working correctly.
If either test indicates failure then the modem has failed and will require return to
factory for replacement.

Modem Speed
The fex21 Internal modem can sometimes become slow and laboured for
communications. If this happens there Is a way to speed up the communications
process. By issuing a dial string command within the extra settings option of the
dial properties the user can force the system to amend it’s baud rate and
increase the throughput of data.
The dial string to use is:
ss1=15f10%co
Increasing Comms Baud Rate
The iex21 default baud rate for serial communications when using Active Sync Is
19200. This can be changed by use of the communications option within the
Control Panel.
Tapping the change button will display a drop down list box from which you can
select the required baud rate. The option ‘Serial Port @ 115k‘ is the fastest
available speed.

Battery
Gas Gauge
One subject that has arisen many times in connection with the fex21 Is charge
life. The fex21 gas gauge does not become accurate until the battery has been
charged to 100%. Many users charge the battery to 99% and believe that this
will be sufficient for a working day. It is actually the case that a 99% charge Is
usually more indicative of a charging failure. This value has previously been used
in the Micro Controller as a default dlsplay value. This practice has now been
changed in newer Micro verslons.
In order to ensure the gas gauge is accurate the user must charge the unit to
100% prior to use. At this level the gas gauge resets all it’s values and begins to
display accurate information.
in later versions of the Micro Controller the gas gauge value will have an
adjacent question mark if the system believes it to be inaccurate. One example
of this is when a battery from another unit Is placed in the fex21. The gas gauge
value will not be known by the unit and therefore question mark will be placed
adjacent to the reading.
Please note that as this Information is controlled by the Micro Controller this is
not O/S version specific.
Battery Temperature
The fex21 contains a 1600mAh NIMH main cell for its primary power supply.
Due to the battery chemistry charge temperature is of great importance. The
fex21 battery system will abort charging at 52°C. When this happens, the battery
indicator LED will flash Irregularly.
When the battery is charged for the first time it will almost certainly reach this
critical temperature before it reaches full charge. This means that charging is
aborted before completion and the gas gauge is not reset. If this does happen
then remove the charger and power the unit down for about an hour to allow the
battery to cool, Re-insert the charger and power the unit back up to continue
charging. In this instance charging may complete within a few minutes.
Back-up Battery
The lack of back-up battery information has caused some confusion with many
customers. Unlike many other CE devices the fex21 is equipped with a
rechargeable backup cell. This cell is constantly trickle charged from the main
battery. An unfortunate side effect of this recharge procedure is that a value
cannot be obtained for remaining battery life. It is for this reason that the backup
battery power remaining screen within the operating system is greyed out. This
is normal for the fex21 and does not indicate battery failure.
45 24/08/00
Qrmomx“ mfifixfl
Cards
CF Insertion
As with all CE devices the compact flash slot does not provide hot swap
capability. The fex21 should be powered down before a compact flash card is
inserted and it must be warm reset before the card is used.
If a compact flash card Is inserted with the unIt powered up it will usually cause a
system lockup. This lockup will not be disastrous and can usually be recovered
by warm resetting the unit. However, this situation can be easily avoided by
ensuring the system is powered off before card Insertion and warm reset
immediately after card insertion. This is done so that Windows CE can register
the card during reset.
Unknown PC card
All PC cards require windows CE drivers to be installed before use in the fex21,
or any CE device. A wide variety of cards already have support built into
Windows CE by default, particularly many communications cards. However,
some cards require drivers to be obtained from the manufacturer before use, If a
card does not have support built into the system an error message:
Unknown Card In Slot x (Where x is the slot number Into which the card
was inserted)
Will be displayed within a dialog box on screen. The appearance of this error
message will require the user to obtain CE specific drivers for that card. If no
drivers are available then the card cannot be used within the Windows CE
operating system.
There was previously a fault whereby the system reported this error message
when the drivers were installed. This fault was fixed in the Husky Service Patch
and subsequently incorporated In the update to Operating System version 3.01,
therefore this will not affect correctly configured systems.
Screen Noise When Writing to CF
The fex21 will generate mild screen interference when writing large files to a
compact flash card. This Is not causing damage to any part of the device and
can be safely ignored.
46 24/08/00
ernomx" mwfix“
Active Sync
Baud Rate Changes
As mentioned In ‘Increasing Comms Baud Hate’ earlier in this guide it is
possible to change the CE default communications baud rate. When this
baud rate is changed It can cause minor problems to the Active Sync
connection. Active Sync has an auto-baud facility that allows the PC
software to detect the baud rate being used by the handheld and adjust
accordingly. Usually when the handheld baud rate is changed the PC will
fail to connect on the first attempt. If this happens the user should initiate
another comms attempt manually by utilising the PC link option.
Utilising this option will force the handheld to retry communications.
Cable Requirements
Many customers have attempted to use their existing PC comms cables to
communicate wIth the fex21. Although this can work with basic
communications it is not recommended. The fex21 is supplied with it’s
own custom designed cable. This cable has been thoroughly tested for
use and also contains the correct level of shielding. This is the only cable
approved for use with the 19x21. When attempting to diagnose any
communications problem it is the cable that should be checked first.

Qrmomx“ m‘bfixn
b Storage Requirements
Handheld Device
For optimum performance the fex21 should be stored In a dry environment
free from direct sunlight at room temperature when not in use.
The maximum storage temperature for the fex21 is +60°C and the
minimum storage temperature is -20°C. Unlike the operating
temperature the storage temperature Is the same for all devices.
The device should not be stored at extremes of temperature. For example
leaving the fex21 on the dashboard of a vehicle In direct sunlight could
cause damage to the unit.
Any Important data held on the device should be backed up before placing
the unit In storage as this can be lost if the batteries are allowed to go flat.
Data stored on Compact Flash will not be lost.
Battery Management During Storage
Allowing the battery to drain completely during storage will cause
irreversible damage to the cells and lower the overall charge capacity this
can be avoided by using the correct storage method.
If the fex21 is being stored for extended periods with the main power cell
installed the battery must be fully charged before storage and
subsequently re-charged every 30 days thereafter. By doing this the user
will avoid capacity loss within the cell.
An fex21 battery that is being stored externally to a unit will need to be re-
charged every 90 days to avoid capacity loss.

Battery Life Too Short
One thing that causes problems on any mobile computer ls battery life. Users
will always complain that battery life is too short. Below are a few things that can
be done to maximise battery life on the fex21.
System time-outs
The system time-outs, l.e. the backlight and power down time-outs, should
be set to as short a period as possible. The unit should be allowed to
enter suspend at the earliest opportunity. On entering suspend the devlce
will automatically save the current settings and the system will resume
where the user left off. This means that all the user has to do is press the
power key to resume work.
Backllght Usage
The unit backlight should be used only when necessary. Although the
system deslgn makes use of low power components the backlight still
draws a signlficant amount of power over normal usage. The backlight
should be used only when necessary and allowed to time-out at the
earliest opportunity.
Ac Power
It is recommended that the fex21 be used on external power wherever
possible. This will help to conserve battery power and top up the battery
level where allowed.
PCMCIA
When using PC Cards the user should look specifically for low power
versions. The PC Cards should be allowed to power down at the earliest
opportunity and should not remain active when not In use.
Care should be taken when choosing the style of card to use, for example
when deciding on mass storage media a flash card should be used in
preference to a spinnlng disk drive wherever posslble. Spinning drives
draw significantly more current than flash cards.
Damaged or Old Batteries
Batteries that have exceeded their useful life (500 charge cycles) or have
been damaged as a result of extended storage without charging can have
a significantly reduced charge capacity. In this instance the batteries will
need replacing.
Version 1.00 49 24/03/00
Qrmomx“ nus-«WEN
Unit WIII Not Power Up
Occasionally the fex21 will fall to power up at first attempt. This is almost always
due to power problems within the unit and usually occurs after a prolonged
period of storage. There are several options to try when this happens:
As a first option attempt to warm reset the device.
If the Warm Reset does not work then a cold reset should be tried, note that this
will destroy all RAM stored data on the device.
If both of these options fall It suggests the unit does not contain enough power to
re-boot, the system should be placed on external power and the reset sequences
tried again.
If this option fails then leave the unit on charge for as long as possible, up to a
maxlmum of 24 hours, and try to reset again.
It all of the above tail then leave the unit on charge without a main battery
installed for a period of several hours and once again try to power the machine
up.
Finally, If one is available, try powering the unit with a battery from a known good
fex21. This may prove a damaged battery Is belng used.
Usually one of the above methods will re-start the system, however if they all tell
it is usually an indication of hardware failure and will require the unit to be
returned for repair.
