FCC and RSS-210 Regulations

This device complies with Part 15 of the FCC Rules and RSS-210 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.

FCC WARNING : Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipm ent.

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 in 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.

FCC Radiation Exposure Statement

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. The Wireless LAN adapter
(KCS) has been tested and found to comply with the Federal Communications Commission (FCC) guidelines
on radio frequency energy (RF) exposures. The maximum SAR level tested for the Wireless LAN adapter
(KCS) has been shown to be 1.2 W/kg at Body.

IC Exposure of Humans to RF Fields

The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not
emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable
from Health Canada’s website www.hc-sc.gc.ca/rpb

1.5 Transferring Data

r

A

 Using radio link

Using radio waves, the BHT can transfer data to an access point in a spread spectrum communications
system.

If ther e are too many communi cations err ors, first make sur e that the built- in antenna in the BHT
points directly at an access point because the 2.4-GHz band requires a mor e or less straight line path.

Host compute

ccess point

Built in antenna

For data transfer using radio li nk, it is necessary to configure a wire less local area network (wireless
LAN) connecting the BHT and access points.

6

Chapter 1 Quick Guide

 Using infrared link

The BHT uses infrared rays to transfer data to IrDA-compliant devices (communication unit CU or other
BHTs).

Communication with the CU

Place the BHT on the CU (option) as shown below.

The CU-301 or CU-321 can be connected to the host with an RS-232C or USB interface cable,
respectively.

In a LAN communications system, use the CU-311 that can be connected to Ethernet with an Ethernet
interface cable.

Communication between BHTs

BHT

• 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 15 cm (5.91") or less.

• 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.

 CU-301/321 and RS-232C/USB Interface Cable (options)

The CU-301/321 is an optical communication unit for the BHT-300 series. It controls data and program
transfer between the BHT and host computer. It communicates with the BHT using infrared (Ir) light and
with the host computer over an RS-232C cable (for CU-301) or USB cable (for CU-321).

You can 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-301/321 where you

 BHT-BASIC4.0 Transfer Utility (option)

Running on the host computer, this utility transfers files between the BHT and the host computer, using
YMODEM or BHT-Ir protocol.

Software Structure

System Programs and JIS Level 1 & Level 2 fonts are resident in the system area and user area,
respectively.

To execute user programs, you should download the program files (*.PD4) into the user area.

To use data files (e.g., good master files) required for execution of user programs, you should download
those data files before execution of user programs. Those files will be stored in the user area.

Host compute

 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 can 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 BHT-BASIC.

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 Kanji characters of 16-dot and 12-dot fonts and their double-width ones 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 Section 2.5.3, "[ 10 ] Deleting Font 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 the BHT-BASIC4.0 Transfer Utility.

• 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 battery cartridge where any inflammable
gases may be emitted; doing so could cause fire.

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

• The BHT has an integrated rechargeable backup power source which backs up the memory an
calendar clock in the BHT when no battery cartridge is loaded or the voltage level of the batter
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 unuse

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.

• If you leave the BHT without a battery cartridge loaded for a long time, the memory contents will
no longer be backed up so that the message "Contact your administrator.

ote the err or 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 Section 2.3.6,
"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 battery cartridge or stain them. Doing so could result in
BHT failure or cartridge charging failure. It is recommended that you wipe those battery cartridge
terminals and the BHT's charge terminals with a dry, soft cloth periodically.

 Checking the Battery Voltage Level

Pressing the ENT key while holding down the SF key displays the current voltage level of the power
source (battery cartridge) as a bar indicator. (Releasing those keys erases the indication.)

• Before battery replacement, be sure to turn the BHT off. Within three minutes from the removal of
the battery cartridge, load the battery cartridge to avoid data loss. After battery replacement, turn
the BHT on and check its operation.

• You may charge the battery cartridge with the optional CU-301/321/311 communication unit o
optional CH-351/CH-201 charger. For the charging procedure using the CU-301/321/311, refer to
Chapter 5. For that using the CH-351/CH-201, refer to the "CH-351 User's Manual"/"CH-201
User's Manual."

• If the "Replace the batteries!" or "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 batter
may not have run out.

Only use the dedicated charger (CU-301/321/311 or
CH-351/CH-201) for charging the rechargeable battery
cartridge.

Using a different type of charger could cause battery-rupture or
leakage of battery fluid and result in a fire, bodily injury, or
serious damage to property.

Never charge a wet or damp battery cartridge.

[ 2 ] Downloading

If you download a file having the same name as one already used in the user area of the target memory
in the BHT, then the newly downloaded file replaces the old one.

If no auto-start executable program has been specified (in Section 2.5.3, [4.1]), turning the BHT on
lets the directory manager start the first loaded one out of user programs (.PD4) in the BHT--the
program that appears on the top of the EXECUTE PROGRAM menu shown on the previous page.
Taking this into account, determine the file downloading order. For details, refer to Section 2.7,
"Starting Up User Programs."

On the SYSTEM MENU, selecting "2: DOWNLOAD calls up the

To return to the SYSTEM MENU, press the C key.

Preparation for Copying between the BHTs

Before downloading to the BHT from another BHT, make the following preparation:

• At each BHT, set the interface port. The default is an IrDA interface (Optical).

Interface setting procedure: Starting on the SYSTEM MENU, select "4:SET SYSTEM,"

"5:COMMUNICATION," and "3:COM PORT." On the SET COM DEFAULT PORT screen,
select the IrDA interface (Optical) or direct-connect interface (Connector) of "2:SYSTE
MODE."

• At each BHT, set the FIELD SPACE to "Ignore" on the communications protocol option screen to

trim trailing spaces in data fields. The default is "Ignore." For the setting procedure, refer to Section

2.5.3, [4.5].

• When using the direct-connect interface, pull out the connector cover on each BHT to expose the

direct-connect interface port. Connect the BHTs via those ports with the direct-connect interface
cable (having 3-pole mini stereo plugs). For the details about the cable, refer to Chapter 3, Section

3.2.

• On the uploading BHT, run System Mode and select "3:UPLOAD" and "3:HT<-->HT COPY."

INVERT (Black-and-white inverted label reading function)

This function makes it possible to read white bars on a black background.

Activating this function might increase the frequency of bar-code reading errors. This function shoul
usually be set to OFF.

DECODE LEVEL

You can set the decode level. Decreasing the level value increases the bar-code 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 entry range of the level value is from 1 to 9 and the default is 4.

62

Chapter 2 Getting Started the BHT and System Mode

MINIMUM DIGITS (Minimum number of digits to be read for ITF, STF, or Codabar)

You can determine 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 entry 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 3 for STF.
