?

If the BHT fails to read due to specular effects or

other factors, change the scanning angle of the
reading window or the distance from codes as
shown at right, and try it again. (Specular effects
occur when the reflection of the light from the bar
code becomes excessively strong. This can easily
happen when the reflecting surface is polished or
covered with vinyl.)

?

The laser light indicates the scanning range as a

guide. The indicated scanning range will deviate a
little bit from the actual one. Keep the BHT so that
the laser light comes to almost the center of the
bar code height.

?

The bar code reading procedure may differ depending upon the application used,

so follow the application’s manual.

?

Before reading labels, clean them if stained.

?

Avoid using the BHT in direct sunlight. The BHT might fail to read

correctly.

?

To read bar codes on curved surfaces, apply the bar -

code reading window

to the center of each bar code at a right angle.

?

If you pull the bar-code rea

ding window away from bar codes, the actual

scanning range will become narrower than the range covered by

the

illumination LED.

The light intensity of the laser light or illumination LED will var

y

depending upon the scanning conditions and variation of its elements.

17

Using Radio Link and Bluetooth® Wireless

Communication Link

The BHT-400BB- CE/400BWB-CE supports spread spectrum communication.

• If there are too many communications errors, first make sure that the
BHT-400BB- CE/400BWB-CE points directly at an access point because the

2.4-GHz band requires a more or less straight line path. Note also that the
low-power radio waves have trouble passing through human bodies and other
obstacles along that path.

• This link will not operate properly in the vicinity of microwave ovens, industrial
heaters, high-frequency medical equipment, and other sources of radio waves in
the 2.4-GHz band.

• Electromagnetic noise from personal computers, refrigerators, and other home
appliances can also interfere with link operation.

• Environmental factors that can also interfere with link operation include large
metallic objects, metallic dust, or metallic walls in the vicinity of the path and
vibration at either end.

• In the vicinity of wireless LAN devices using radio waves in the 2.4 GHz band,
Bluetooth® wireless communication link operation may cause interference to radio
communications, resulting in decreased communications speed or
communications failures.

To System Designers:

•

Before developing the application, make sure that the intended

environment is free of the interference factors above and thus actually

capable of supporting link operation.

•

Assume that there will be communications failures requiring robust retry

capabilities in the software.

• When introducing the BHT link operation into an environment where
equipment using radio waves in the 2.4-

GHz band operates or when

introducing such

equipment after the introduction of the BHT link

operation, be sure to confirm that the BHT radio link operates properly

with all equipment being in operation beforehand.

•

If the environment of the radio communications system is changed after

the introdu

ction (e.g., newly installed household appliances and

movement/addition of shelves or objects), then confirm that the radio

link

operates properly again before the actual use.

18

Using Infrared Link

??CU- 400

Make sure that the BHT is securely in the CU-400.

Shield the IrDA

interface from direct sunlight, ambient intense lighting

(inverter-driven fluorescent lighting, in particular), and other potential
sources of infrared radiation. Sources to watch out for include remote
control units for television sets and the like.

19

Loading the Battery Cartridge

Before the first use of the BHT, be sure to load the battery cartridge as shown below.
The battery cartridge is not loaded in the BHT when shipped from the factory.

(1) Turn the BHT upside down.
(2) Slide the release buttons in the direction shown below and remove the battery

cartridge cover.
(3) Push the battery cartridge into the BHT.
(To remove it, first make sure that the BHT is turned off. Slide the release

buttons, remove the battery cartridge cover, and pull up the battery pull strap.)
(4) Set the battery cartridge cover back into place and slide the release buttons to

the original position.
(5) Place the BHT on the CU-400 to charge the rechargeable battery cartridge.

• The BHT integrates a rechargeable backup power source which backs up
the memory and calendar clock in the BHT when no battery cartridge is
loaded or the voltage level of the battery cartridge drops below the
specified level. The backup power source is automatically charged by the
battery cartridge.

When you first load the battery cartridge after purchase or you load it

after leaving the BHT

unused for a long time, do not remove the battery

cartridge for at least 48 hours after that loading. This is for charging

the

memory backup source integrated in the BHT.

• For handling notes to be observed at the time of battery replacement,

refer

to the "Battery Replacement Notes" on page 20.

21

Calibrating the Touch Screen

At the first use of the BHT, you need to calibrate the touch screen and set up the
calendar clock. Press the power key to turn on the BHT. The calibration screen
appears, so follow the on-screen instructions. If nothing appears, first perform a
"cold boot" (described on the "Warm and Cold Booting" on page 21).

?

message and starts preparation for shutdown.

When the above message is displayed, do not remove the battery cartridge.
If you do so, the data stored in the BHT may be lost.

23

Battery Replacement Notes

??When is battery replacement needed?

If the "Charge the battery!" appears on the LCD, replace the rechargeable battery
cartridge with a fully charged one.

If you leave the BHT without replacing the rechargeable battery cartridge, the
integrated calendar clock and data stored in the BHT’s RAM can no longer be
backed up. The calendar clock may stop and RAM data may be lost.

• Be sure to turn the BHT off before battery replacement.

• Replace the bat tery cartridge quickly. Load a charged battery cartridge
within 3 minutes after the removal to avoid data loss.

• After battery replacement, turn the BHT on and check the BHT operation.

• If you leave the BHT with no battery cartridge loaded for a long tim

e, the

contents of the memory may no longer be backed up so that the data

stored in the BHT’ s

RAM may be lost. It is recommended that important

data be saved into the FLASH folder or uploaded to the host computer.

• The battery cartridge will gradually det

eriorate during the repeated cycles

of charging and discharging due to its properties. When the battery

operation period becomes shortened due to its deterioration even if it has

been charged for the specified hours, replace the battery cartridge with a

new one.

• Use only DENSO WAVE-authorized battery cartridges and chargers.

•

Never dispose of battery cartridges into a fire. They should be recycled

properly. Do not throw them in a trash.

If some error occurs when the power is turned on or during program execution, one
of the following error messages will appear on the LCD.

System Program error

? Problem

A System Program error has occurred.

? Solution

Contact your system administrator.

Low battery warning

? Problem

When the BHT

is turned on or off or during

execution of program, the battery output level has
dropped below a specified lower limit.

If low battery is det

ected, the BHT displays

this

message for approx. 2 seconds and

beeps three

times (for 0.1 second per beep).

After that, it

will resume previous regular

operation.

? Solution

The battery cartridge will need to be

recharged

before long. Replace or recharge

the battery

cartridge.

35

Shutdown due to low battery

? Problem

When the power is turned on or off or during

execution of programs,

the battery output level has

lowered to the ex

tent the BHT can no longer

operate.

If lower battery is detected, the BHT beeps

five

times (for 0.1 second per beep) and

then turns

itself off. Depending upon the

battery level, the beeper may n

ot sound five

times.

? Solution

Replace or recharge the battery cartridge.

Service life warning for backup battery

? Problem

The backup battery has been charged/discharged

by the specified number of times so that the battery

capacity lowers below the specified level.

? Solution

Replace the backup battery. For the replacement
procedure, refer to the
BHT-400BB- CE/400BWB-CE User's Manual.

36

Proper Care of the BHT

Wipe the BHT's charge terminals and battery cartridge terminals with a cotton swab
or the like periodically. Clean the BHT housing with a dry, soft cloth. Before cleaning,
be sure to turn the BHT off.

?

Never use benzene, alcohol, or other

organic

solvents. The housing may be

marred or the

paint may come off.

?

Never rub or strike the liquid crystal

display

(LCD) with anything hard. The

LCD surface will

be easily scratched or broken.

?

When cleaning the keypad, do not

scrub the

surface too hard or

pull on the keys. Doing so

may break the keys.

?

If the BHT becomes smudged, wipe it with a soft cloth that has been moistened in

soapy water (always use neutral detergent) and wrung out thoroughly.

Dust or dirt accumulating on the clear plate of the bar-code reading window will
affect reading performance. If you use the BHT in dusty areas, therefore,
periodically check the clear plate of the bar-code reading window and clean it if
dusty.

?

To clean the plate, first blow the dust away with an airbrush. Then wipe the plate

with a cotton swab or the similar soft one gently.

?

If sand or hard particles have accumulated, never rub the plate; doing so will

scratch or damage it. Blow the particles away with an airbrush or a soft brush.

37

Handling Notes

?

An early upload of gathered data is recommended, since the data stored in the

RAM might be affected by the so-called "soft error" or other environmental
phenomena.

?

Do not use the BHT in the vicinity of radio equipment. The BHT may malfunction.

?

Avoid storing the battery cartridge in a hot place. The battery capacity may be

decreased.

?

Do not touch the battery cartridge terminals or BHT's charge terminals by hand or

stain them. Doing so could result in BHT's malfunction or cartridge charging
failure.

?

When connecting or disconnecting cables, do not plug or unplug at an angle and

do not pull them strongly. Doing so will result in a machine failure.

?

If the BHT has been stored in a hot (50?C to 60?C, 122?F to 140?F) and humid

place, allow it to sit at room temperature and humidity for at least one day before
use. Using the BHT with its inside being hot will fail to scan or result in a machine
failure.

?

If the stylus wears so that its tip becomes sharpened, replace it.

?

In environments where static electricity can build into significant charges, do not

operate the BHT. Doing so will result in malfunction or machine failure.

?

Avoid dropping the BHT or letting it undergo any shock or impact. Doing so will

break or damage the BHT.

?

If the "Charge the battery!" message appears after the BHT undergoes any shock

or impact, turn the BHT off and on and then check the battery output level. The
battery may not have run out.

?

Battery cartridges should be recycled properly in conformity with local codes and

regulations.

US and Canada Regulations

BHT-400BWB- CE(BHT-420BWB-CE/470BWB-CE) complies with Part 15 of FCC
rules and RSS-Gen of IC rules.

Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and

(2) this device must accept any interference received, including interference that

may cause undesired operation.

NOTE: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used on
accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to correct
the interference at his own expense.

NOTE: This Class A digital device apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003 du

Canada.
FCC WARNING: Changes or modifications not expressly approved by the party

responsible for compliance could void the user’s authority to operate the
equipment.

CAUTION: Radio Frequency Radiation Exposure
The available scientific evidence does not show that any health problems are

associated with using low power wireless devices. There is no proof, however,
that these low power wireless devices are absolutely safe. Low power Wireless
devices emit low levels of radio frequency energy (RF) in the microwave range
while being used. Whereas high levels of RF can produce health effects (by
heating tissue), exposure to low -level RF that does not produce heating effects
causes no known adverse health effects. Many studies of low -level RF exposures
have not found any biological effects. Some studies have suggested that some
biological effects might occur, but such findings have not been confirmed by
additional research. Barcode Handy Terminal (BHT-420BWB-CE,
BHT-470BWB- CE) has been tested and found to comply with FCC/IC radiation
exposure limits set forth for an uncontrolled equipment and meets the FCC radio
frequency (RF) Exposure Guidelines in Supplement C to OET65 and RSS-102 of
the IC radio frequency (RF) Exposure rules. Please refer to the SAR test report
that was uploaded at FCC website.

Do not place hands or body near the antenna section to avoid RF exposure.
This transmitter must not be co-located or operated in conjunction with any other

antenna or transmitter.
