SAFETY PRECAUTIONS
Be sure to observe all these safety precautions.
■Please READ thro gh this man al caref lly. It will enable yo to se the BHT-5000
correctly.
■Always keep this man al nearby for speedy reference.
WARNING Alerts yo to those conditions which co ld ca se seri-
o s bodily inj ry or death if the instr ctions are not
followed correctly.
CAUTION Alerts yo to those conditions which co ld ca se minor
bodily inj ry or s bstantial property damage if the in-
str ctions are not followed correctly.
Meaning of Sy bols
A triangle ( ) with a pict re inside alerts yo to a warning of danger. Here
yo see the warning for electrical shock.
A diagonal line thro gh a circle ( ) alerts yo to something yo sho ld not
do; it may or may not have a pict re inside. Here yo see a screwdriver
inside the circle, meaning that yo sho ld not disassemble.
A black circle ( ) with a pict re inside alerts yo to something yo MUST
do. This example shows that yo MUST npl g the power cord.
Strict observance of these warning and ca tion indications are a MUST for preventing
accidents which co ld res lt in bodily inj ry and s bstantial property damage. Make
s re yo f lly nderstand all definitions of these terms and related symbols given
below, before yo proceed on to the text itself.

WARNING
Handling the battery cartridge
• Never disassemble or heat the battery
cartridge, nor p t it into fire or water;
doing so co ld ca se battery-r pt re or
leakage of battery fl id, res lting in a
fire or bodily inj ry.
• Do not carry or store the battery car-
tridge together with metallic ball-point
pens, necklaces, coins, hairpins, etc.

nal pins, ca sing the batteries to r p-
t re or the battery fl id to leak, res lt-
ing in a fire or bodily inj ry.

cloth.
• Never se benzene, alcohol, or other or-
ganic solvents. The ho sing may be
marred or the paint may come off.
• Never r b or strike the liq id crystal dis-
play (LCD) with anything hard. The LCD
s rface will be easily scratched or bro-
ken.
• If the BHT or CU becomes sm dged, moisten a soft cloth with ne tral detergent and
wring it o t thoro ghly. Wipe the BHT or CU with the cloth and then go over it again
with a dry cloth.

1.1 Reading Bar Codes
Turn on the BHT power, bring the bar-code reading window up to the bar code to be
scanned, and press the trigger switch. The BHT-5000 lights the illumination LED and
reads the bar code.
When the BHT-5000 has read the bar code successfully, the reading confirmation LED
will illuminate in green.
•If the BHT-5000 fails to read, change the reading angle of the bar-code reading
window or the distance from bar codes, and try it again.
•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 for long-range scanning
so that the entire bar code comes into the illumination range covered by the
illumination LED. The BHT-5000 can read bar codes at a maximum distance of 20
cm (7.9")* from the bar-code reading window.
*Under the following conditions:
- Ambient illuminance: 500 lux (fluorescent lamp)
- ITF conforming to the UPC Shipping Container Code
- PCS value: 0.9 or more
- Minimum narrow bar width: 1.2 mm min. (47.2 mils min.)
Before reading labels, clean them if stained.
Avoid using the BHT-5000 in direct sunlight. The BHT-5000 might fail to read
correctly.
To read bar codes on curved surfaces, apply the bar-code reading window to the
center of each bar code at a right angle.

1.4 Using the Keypad
■Entering Numerical Data
To enter numerical data, e.g., the quantity of goods, use the ten numerical keys and
ENT key.
For example, to enter the number "120," press 1 , 2 and 0 keys and then press ENT
key.
If you key in any wrong value, press C key (or press C key while holding down SF
key) and then enter the correct one.
■Selecting Tasks
If the LCD shows the selection items (xxx) prefixed by numerals (e.g., 1: xxx, 2: xxx),
use the numerical keys to select a desired item and press ENT key to execute.
If a YES/NO screen (e.g., 1: YES, 2: NO) appears, press 1 key for YES response and 2
key for NO response.
