SAFETY PRECAUTIONS
Be sure to observe all these safety precautions.
Strict observance of these warnings and cautions is a MUST for preventing
accidents that could result in bodily injury and substantial property damage. Make
sure you fully understand all definitions of these terms and symbols given below
before you proceed to the text itself.
Alerts you to those conditions that could cause
serious bodily injury or death if the instructions are
not followed correctly.
Alerts you to those conditions that could cause minor
bodily injury or substantial property damage if the
instructions are not followed correctly.
Meaning of Symbols
A triangle ( ) with a picture inside alerts you to a warning of danger.
Here you see the warning for electrical shock.
A diagonal line through a circle ( ) warns you of something you should
not do; it may or may not have a picture inside. Here you see a
screwdriver inside the circle, meaning that you should not disassemble.
A black circle ( ) with a picture inside alerts you to something you
MUST do. This example shows that you MUST unplug the power cord.
To System Designers:
• When introducing BHTs in those systems that could affect human
lives (e.g., medicines management system), develop applications
carefully through redundancy and safety design which avoids the
feasibility of affecting human lives even if a data error occurs..
Handling the battery cartridge
• 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.
• Never put the battery cartridge into a microwave oven or
high-pressure container.
Doing so could cause the batteries to break, generate heat, rupture
or burn.
• Avoid dropping the batter y cartridge or letti ng it underg o any shock or
impact.
Doing so could cause the batteries to break, generate heat, rupture
or burn.
• Never charge the lith ium-ion batter y cartridge where any inflammabl e
gases may be emitted; doing so could cause fire.
• Only use the d edicated charger for charging the 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.

Handling the BHT
• Never put the BHT into a microwave oven or high-pressure container.
Doing so could cause the BHT to break, generate heat, rupture or
burn.
6
Handling the battery cartridge
• Never charge a wet or damp rechargeable battery cartridge.
Doing so could cause the batteries to break, generate heat, rupture
or burn.
Handling the BHT
• If smoke, abnormal odors or noises come from 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 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.
• Do not use batteries or power sources other than the specified ones;
doing so could generate heat or cause malfunction.
Never
disas-
sembly
• Never disassemble or modify the BHT; doing so could result in an
accident such as break or fire.
• Never put the BHT in places where there are excessively high
temperatures, such as inside closed-up automobiles, or in places
exposed to direct sunlight.
Doing so could affect the housing or parts, resulting in a fire.
• Avoid using the BHT in extremely humid or dusty areas, or where
there are drastic temperature changes.
Moisture or dust will get into the BHT, resulting in malfunction, fire or
electrical shock.
• In environments where static electricity can build into significant
charges (e.g., if you wipe off the plastic plate with a dry cloth), do not
operate the BHT. Doing so will result in malfunction or machine
failure.
Handling the BHT
• When connecting or disconnecting the direct-connect interf ace cable
to/from the BHT, do no plug or unplug at an angle and do not pull the
cable 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.
Limited Warranty on Software Products
In no event will DENSO WAVE INCORPORATED be liable for direct, indirect,
special, incidental, or consequential damages (including imaginary profits or
damages resulting from interruption of operation or loss of business information)
resulting from any defect in the software or its documentation or resulting from
inability to apply the software or its documentation.

line, to the preceding character,
and to the next character.
Numerical keys
Used for data input.
Function keys
Used for choosing
functions.

Reading Bar Codes
Turn the BHT on, bring the bar-code reading window to the bar code to be scanned,
and press the trigger switch. The BHT 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.
Illumination range covered
by the illumination LED
Trigger switch (M4 key)*
Indicator LED
(Illuminates in green when the
BHT has read the bar code
successfully.)
* The trigger switch function is
assigned to both of the M3
and M4 keys by default.
• 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.)
• To read bar codes wider than the readable area
of the bar-code reading window, pull the
bar-code reading window away from bar codes.
The BHT can read bar codes at a maximum
distance of 45 cm (17.7") from the bar-code
reading window, respectively. **
** Under the following conditions:
- Ambient illuminance: 500 lux (fluorescent lamp)
- ITF conforming to the UPC Shipping Container
Code
• The bar code reading procedure may differ depending upon the application use d,
so follow the application’s manual.
