• 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 ballpoint 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.

16

Chapter 2 Getting Started the BHT and System Mode

• 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 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 unuse

d

for a long time, do not remove the battery cartridge for 1 0 minutes or more after that loading. T his 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.

N

ote 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 Section 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 battery cartridge or stain them. Doing so could result in

a

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 c urrent voltage level of the power
source (battery cartridge) as a bar indicator. (Releasing those keys erases the indication.)

17

 Low Battery Indication

Low battery warning

If the output voltage (of the battery cartridge) drops below a specified lower level while the BHT is in
operation, the BHT displays the following warning message for approx. 2 seconds and beeps three
times. After that, it will resume the previous regular operation.

The battery cartridge will need to be recharged before long. Recharge it as soon as possible.

Shutdown due to low battery

If you continue to use the BHT without replacement or recharge of the battery cartridge after the low
battery warning message appears, then the BHT displays the following message, beeps five times, and
then turns itself off. Depending upon the battery level, the beeper may not sound five times.

Replace or recharge the battery cartridge.

If you download a file having t he same name as one already used in the use r 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 o n

lets the directory manager start the first loaded one out of user programs (.PD4) in the BHT--the

p

rogram 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
screen shown at left.

[1] FILE: Downloads a user program file or data file to

the user area of the BHT.

[2] HT<-->HT COPY: Downloads all of the files, system

parameters, and calendar clock data stored
in the connected BHT.

This function enables copying between the

BHTs.

For the preparation to be made preceding the

start of this function, refer to

Select a desired item by using the numerical keys or F5 and F6 keys,
and the selected item becomes highlighted. Then press the ENT key.

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:SYSTEM
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 t he 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 cab le, refer to Chap ter 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 ba r-code reading errors. T his function shoul

d

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.

57

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.

If you define the M1 key as a backlight function on/off key, pressing the M1 key activates or deactivates
the backlight function.

In user programs, a string data can be also assigned to these magic keys.

The backlight function on/off key can be assigned only to any one of M1 through M4 keys. The key
defined more recently will act as a backlight function on/off key and one defined earlier will be
ignored.

That is, if you define the M1 and M2 keys a s a backlight fu nction on/off key in this orde r, the M2 key
will work as a backlight function on/off key and the M1 key's entry will be ignored.
