WARNING
Handling the battery cartridge
•Never disassemble or heat the re-
chargeable 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.
Never
put me
into fire!
SAFETY PRECAUTIONS
Be sure to observe all these safety precautions.
Strict observance of these warning and caution indications are a MUST for
preventing accidents which could result in bodily injury and substantial prop-
erty damage. Make sure you fully understand all definitions of these terms
and related symbols given below, before you proceed on to the text itself.

WARNING
Do not
short-
circuit me!
Charge only
with the
dedicated
device.
Undedicated
•Do not carry or store the battery car-
tridge together with metallic ball-
point pens, necklaces, coins, hair-
pins, etc.
Doing so could short-circuit the ter-
minal 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, rup-
ture or burn.
•Only use the dedicated charger (CU-
7001, C-700 or C-750) for charging
the rechargeable battery cartridge.
Using a different type of charger
could cause battery-rupture or leak-
age of battery fluid and result in a
fire, bodily injury, or serious damage
to property.
•Never charge the rechargeable battery cartridge where any in-
flammable gases may be emitted; doing so could cause fire.

Handling the BHT
•The BHT-100BF 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-100BF complies with Laser Safety Standard, Class II
of 21 CFR Chapter 1, Subchapter J.
The BHT-100BF does not mount beam attenuator and laser
radiation emission indicator required by this standard. Instead,
the software-controlled Magic keys (see Section 2.2
"Components and Functions") function as them because the
laser light is not enabled without the Magic keys pressed.
WARNING
•Do not look into the light source through the reading window or
point the light source towards the eyes.
The light emitted through the reading window is harmful to the
eyes.
•Do not poke at the eyes with the stylus that comes with the
BHT.

•If foreign material or water gets into
the BHT, immediately turn off the
power, pull out the battery cartridge,
and contact your nearest dealer.
Failure to do so could cause smoke
or fire.
•If you drop the BHT so as to damage
its housing, immediately turn off the
power, pull out the battery cartridge,
and contact your nearest dealer.
Failure to do so could cause smoke
or fire.
•Never disassemble or modify the BHT; doing so could result in
an accident such as break or fire.
•If smoke, abnormal odors or noises come from the BHT, imme-
diately turn off the power, pull out the battery cartridge, and
contact your nearest dealer.
Failure to do so could cause smoke or fire.
Never
disassemble
CAUTION
•Do not use batteries or power sources other than the specified
ones; doing so could generate heat or cause malfunction.
•In environments where static electricity can build into signifi-
cant charges (e.g., if you wipe off the plastic plate with a dry
cloth), do not operate the BHT. Doing so will result in malfunc-
tion or machine failure.
•Touch the LCD only with the stylus that comes with the BHT.
Using the tip of a pen or any pointed object will result in a dam-
aged or broken LCD.

Reading Bar Codes
•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 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 the BHT-100QF/100BF User’s Manual.)
•The bar code reading procedure may differ depending upon the
application used, so follow the application's manual.
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 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.

• 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.

Using Radio Link
•If there are too many communications errors, first make sure that the BHT
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, in-
dustrial 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.
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.

Using Infrared Link
■CU-7000
Make sure that the BHT is securely in the CU-7000.
Shield the optical 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.

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) Charge the rechargeable battery cartridge.
(2) Turn the BHT upside down.
(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.)
•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 10 minutes or more after that loading. This is for charging
the memory backup source integrated in the BHT.
•If you will not be using the BHT for a long time, take the specified
procedure given in "Battery Replacement Notes."
