Handling the BHT

• The BHT-100B uses a laser light for indicating the scanning range.
The intensity of the laser light might be too low to inflict bodily injury.
However, do not look into the laser beam.

The BHT-100B complies with Laser Safety Standard, Class II of 21 CFR
Chapter 1, Subchapter J.

The BHT-100B does not mount beam attenuator and laser radiation
emission indicator required by this standard. Instead, the software­controlled trigger switches (see Section 2.2 "Components and Func­tions") function as them because the laser light is not enabled without
the trigger switches pressed.

■ Proper Care of the BHT and CU

Clean the housings, battery cartridge terminals, and CU-7001 charge terminals with a
dry, soft cloth. Before cleaning, be sure to turn the BHT power off and unplug the AC
adapter of the CU.

• 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, and do not pull on
the keys. Doing so may break the keys
or cause the keypad to dislocate.

• If the BHT or CU becomes smudged, moisten a soft cloth with neutral detergent and
wring it out thoroughly. Wipe the BHT or CU with the cloth and then go over it
again with a dry cloth.

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

• To clean the plate, first blow the dust away with an air brush. 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 air brush or a soft brush.

1.1 Reading 2D Codes and Bar Codes

BHT-100Q

Turn the BHT power on, bring the reading window to the target code, and press the
trigger switch. The BHT-100Q turns three marker LEDs on to indicate the scanning
range and the illumination LED to scan the code. Keep the BHT stationary in a position
where the target code lies between the right and left markers and the center marker
comes to the center of the target code.

Hold the reading window 4 to 14 cm (1.6 to 5.5 inches) away from codes to be scanned.
When the BHT has read the code successfully, the indicator LED will illuminate in

green and the markers will go off.

• The markers show the left-to-right scanning range. When the scanning distance
is 8.5 to 9.5 cm (3.3 to 3.7 inches), they indicate almost the center of the up-down
scanner’s view. If the distance is out of the range, those markers will deviate
from the center.

• 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 code becomes excessively
strong. This can easily happen when the reflecting
surface is polished or covered with vinyl.)

• The code reading procedure may differ depending upon
the application used, so follow the application's
manual.

2

Chapter 1. Quick Guide

• Before reading 2D codes or bar codes, clean those labels if stained.

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

• To read 2D codes or bar codes on curved surfaces, apply the BHT to the target
code so that the code comes to the center of the scanning range indicated by the
markers.

• Depending upon the code size or cell pitch, the proper scanning distance from
2D codes or bar codes will differ.

• Do not use the BHT in the vicinity of radio equipment. The BHT may malfunction.
At the scanning time, the marker LEDs and illumination LED will come on. The

illumination LED may not come on where it is bright enough for the BHT to
scan. The light intensity of those LEDs will vary depending upon the scanning
conditions and variation of their elements.

3

BHT-100B

Turn the BHT power on, bring the bar-code reading window to the bar code to be
scanned, and press the trigger switch. The BHT-100B emits a laser light to indicate the
scanning range and turns on the illumination LED to scan the bar code.

When the BHT has read the bar code successfully, the indicator LED will illuminate in
green.

• 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 BHT can read bar codes at a maximum distance of 40 cm (15.7")* from the
reading window. (*For details about the scanning conditions, refer to Appendix
A.)

• The bar code reading procedure may differ depending upon the application
used, so follow the application's manual.

Chapter 1. Quick Guide

•

Before reading bar codes, clean those labels 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 BHT to the target bar code so that the
code comes to the center of the scanning range indicated by the laser beam.

•

When you pull the bar-code reading window away from bar codes, the actual
scanning range will become narrower than the range covered by the laser beam.

• Do not use the BHT in the vicinity of personal or amateur radio equipment. The
BHT may malfunction.

The light intensity of the laser light or illumination LED will vary depending
upon the scanning conditions and variation of their elements.

1.5 Transferring Data

■ Using infrared link

Using infrared rays, the BHT may transfer data directly to the host computer equipped
with an IrDA interface port and other IrDA-compliant devices.

• Make sure that there is no obstruction in the light path between the BHT and any
target stations. In infrared communication, you need to keep the BHT and any
target stations within the effective infrared radiation range, usually 10 to 80 cm
(3.94 to 31.50").

• Shield the IrDA interface from direct sunlight, ambient intense lighting (inverter­driven 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.

■ CU-7000 and RS-232C Interface Cable (option)

The CU-7000 is an IrDA-compliant communications unit which is required when your
host computer is not equipped with an IrDA interface port. The CU-7000 exchanges
data and programs with the BHT optically, and with the host computer via the RS-232C
interface cable.

You may directly connect two BHTs with each other by using a commercially available
metal cable having 3-pole mini stereo plugs (as a direct-connect interface cable). You
also connect the BHT directly with the host computer or with the modem by using the
direct-connect interface cable compatible with the target equipment. (NOTE: The
direct-connect interface port of the BHT is not designed to stand frequent connecting/
disconnecting. You are, therefore, recommended to use the CU-7000 where you
expect to do a lot of connecting and disconnecting of the BHT to/from a host compu­ter.)

■ BHT-BASIC Compiler (option)

This Compiler compiles a source program written in BHT-BASIC by an editor of the
host computer running the MS-DOS, into the object program (user program) which
can be used in the BHT. The compiled and linked program file is named "XXX.PD3."
(XXX: File name you can set arbitrarily under the MS-DOS rules) You should download
it to the BHT by using Ir-Transfer Utility C/Ir-Transfer Utility E/Transfer Utility.

13

■ Ir-Transfer Utility C (option)

Running on the host computer, this utility transfers files between the BHT and the host
computer. For its file transfer control procedure, the utility uses the BHT-Ir protocol.
(For the details about the BHT-Ir protocol, refer to Chapter 3, Subsection 3.4.2.)

To transfer files under any of the following conditions, use Ir-Transfer Utility C:

- At transmission speeds of 115200 or 57600 bps (This may be impossible de­pending upon the host computer type.)

- When the BHT is placed on the CU-7000

- Via the direct-connect interface of the BHT

■ Ir-Transfer Utility E (option)

Running on the host computer, this utility transfers files between the BHT and the host
computer. For its file transfer control procedure, the utility uses the BHT-Ir protocol.
(For the details about the BHT-Ir protocol, refer to Chapter 3, Subsection 3.4.2.)

To transfer files under any of the following conditions, use Ir-Transfer Utility E:

- Via an external IR transceiver

- Via an IR port integrated in a computer

■ Transfer Utility (option)

Running on the host computer, this utility transfers files between the BHT and the host
computer. For its file transfer control procedure, the utility uses the BHT-protocol.
(For the details about the BHT-protocol, refer to Chapter 3, Subsection 3.4.1.)

To transfer files under any of the following conditions, use Transfer Utility:

- When the BHT is placed on the CU-7000

- Via the direct-connect interface of the BHT

■ System Programs

The system programs include the following three sets of programs:

Drivers

Drivers is a set of programs that directly controls the BHT hardware. It may be called
up by the BHT-BASIC Interpreter or System Mode.

BHT-BASIC Interpreter

The interpreter interprets and executes instructions in user programs written in BHT­BASIC.

15

System Mode

System Mode is a system program exclusively designed for the effective use of user
programs in the BHT. It sets up the execution environments for those programs; e.g.,
it prepares downloading/uploading conditions, sets the calendar clock, and tests the
BHT components including the LCD, beeper, and keypad. Shown below is the System
Mode menu (SYSTEM MENU).

■ JIS Level 1 and Level 2 Font Files

These files contain font data required for displaying Kanji characters on the LCD.
The BHT can display the Kanji characters not only in the conventional standard-size

font (16 dots wide by 16 dots high) but also in the small-size font (12 dots wide by 12
dots high) in application programs. It can also display the double-width, double­height, and quadruple-size (double-width & -height) Kanji characters of those 16-dot
and 12-dot fonts in application programs.

If you do not need to display Kanji characters, you may delete these JIS font files.
After deletion, the memory area which was occupied by these files can be used as a
user area. For the deleting procedure, refer to Section 2.4, "Initializing the BHT
System" or Subsection 2.5.3, "[ 7 ] Deleting Files."

The names of the JIS font files are:

FNT16J1.FN3 (JIS Level 1 font, 16-dot)
FNT16J2.FN3 (JIS Level 2 font, 16-dot)
FNT12J1.FN3 (JIS Level 1 font, 12-dot)
FNT12J2.FN3 (JIS Level 2 font, 12-dot)

■ User Programs

You can develop application programs to meet individual job requirements by using
the BHT-BASIC Compiler. To download those user programs to the BHT, use Ir­Transfer Utility C/Ir-Transfer Utility E/Transfer Utility.

(3) As shown below, slide the battery cartridge into the BHT until it clicks into place.

(To remove it, press the release button after making sure that the BHT power is
off.)

WARNING

Battery cartridge

Release button

• Never disassemble or heat the battery cartridge,
nor put it into fire or water; doing so could
cause battery-rupture or leakage of battery fluid,
resulting in a fire or bodily injury.

• Do not carry or store the battery cartridge to­gether with metallic ball-point pens, necklaces,
coins, hairpins, etc.

Doing so could short-circuit the terminal pins,
causing the batteries to rupture or the battery
fluid to leak, resulting in a fire or bodily injury.

• Avoid dropping the battery cartridge or letting
it undergo any shock or impact.

Doing so could cause the batteries to break,
generate heat, rupture or burn.

• Never charge the rechargeable battery cartridge
where any inflammable gases may be emitted;
doing so could cause fire.

CAUTION

• Do not use batteries or power sources other
than the specified ones; doing so could gener­ate heat or cause malfunction.

19

• Never charge the dry battery cartridge.

• The BHT has an integrated 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 10
minutes or more after that loading. This is for charging the memory backup
source integrated in the BHT.

• Be sure to turn the BHT off before battery replacement. Replace the battery
cartridge quickly. Load a charged battery cartridge within 3 minutes from the
removal of the cartridge to avoid data loss.

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

• If you leave the BHT with no battery cartridge loaded for a long time, the memory
contents will no longer be backed up so that the message "Contact your adminis­trator. Note the error number. (XXXX)" or "Set the current date and time." may
appear on the LCD.

If you will not be using the BHT for a long time, follow the instructions given in
Subsection 2.3.5, "Battery Replacement Notes."

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

• Do not touch the charge terminals of the rechargeable battery cartridge or stain
those terminals. Doing so could result in a charging failure.

■ Battery Voltage Level on the Status Indicator Line

The battery voltage level is always displayed on the status indicator line.
(For details, refer to Subsection 2.3.4 "Battery Voltage Display.")

20

Chapter 2. Getting Started the BHT and System Mode

■ Low Battery Indication

Low battery indication—Level 1
If the battery output voltage drops below a specified lower level limit while the BHT is

in operation, the BHT displays the following Level 1 message for approx. 2 seconds
and beeps three times. After that, it will resume previous regular operation.

The battery recharge or replacement time will come soon. If the BHT is driven by the
rechargeable battery cartridge, recharge or replace it; if it is driven by the dry battery
cartridge, replace the dry cells.

Low battery indication—Level 2
If you continue to use the BHT without recharge or battery replacement after the Level

1 message appears, the BHT displays the following Level 2 message, beeps five times,
and then turns itself off. Depending upon the battery level, the beeper may not sound
five times.

(When driven by the

rechargeable battery cartridge)

(When driven by the dry battery cartridge)

If the BHT is driven by the rechargeable battery cartridge, recharge or replace it; if it is
driven by the dry battery cartridge, replace the dry cells.

21

•When replacing dry cells, always replace both of them with new alkaline manga­nese batteries (LR6).

• You may charge the rechargeable battery cartridge with the optional CU-7001
communication unit or optional C-700/C-750 charger. For the charging proce­dure using the CU-7001, refer to Chapter 5. For that using the C-700/C-750, refer
to the "C-700 User's Manual"/"C-750 User's Manual."

• If the "Charge the battery!" or "Replace the batteries!" message appears after the
BHT undergoes any shock or impact, turn the power off and on and then check the
battery output level. The battery may not have run out.

WARNING

CAUTION

reading efficiency, but the BHT might misread low-quality bar codes (split or stained).
To the contrary, increasing the level value decreases the bar-code reading efficiency,
but it will diminish the possibility of misreading.

The setting range of the level value is from 1 to 9 and the default is 4.

Marker

You may select the marker ON/OFF mode from the following:

0: Driven by the trigger switch
1: Fixed to ON
2: Fixed to OFF

If you select "1" (Fixed to ON), the markers will keep ON so that power consump­tion is higher than that in other modes and the battery working time becomes short.
Do not disturb this setting unless necessary.

Minimum number of digits to be read for ITF, STF, or Codabar

You may set the minimum number of digits to be read for ITF, STF, and Codabar.
Setting a small number of digits increases the frequency of digit-missing reading or
misreading depending upon how to scan bar codes or the quality of bar codes. On the
other hand, setting a large number will diminish the possibility of those errors.

The setting range is from 2 to 20 for ITF, from 1 to 20 for STF, and from 3 to 20 for
Codabar. The default is 4 for ITF and Codabar, and 2 for STF.

* The minimum number of digits to be read depends on

To return to the TEST menu, press the C key.

• The "QR Code" system supports a split QR code feature ("Structured Append")
which can divide data in a QR code into a maximum of 16 blocks and encode
each of them into a split QR code.

When reading split QR codes, the BHT-100Q beeps in a different way from
usual. That is, when the BHT-100Q reads the first split code, it beeps twice and
enters the split code scanning mode. After that, each time it reads the subsequent
split code, it beeps once. If the BHT-100Q reads the last split code, it beeps three
times and completes the sequence of split code scanning.

The scanned data will not be displayed on the LCD until a sequence of split code
scanning is completed.

If you scan any non-split code midway in a sequence of split code scanning, the
BHT-100Q displays the scanned non-split code, cancels the split code scanning
mode, and discards those split codes being scanned. The same occurs also if you
release the trigger switch or the split code scanning interval exceeds approx. 5
seconds.

The scanning order of split codes is arbitrary. The same split code will never be
double-scanned.

• If the OPTION DATA is set to ON on the SET QRCODE screen in the SET
SYSTEM menu (see [4.4] Setting the special scanning parameters), then the
option data will follow QR code data read.
