gani solvents. The housing may be
marred or the paint may ome off.
• Never rub or strike the liquid rystal dis-
play (LCD) with anything hard. The LCD
surfa e will be easily s rat hed or bro-
ken.
• When leaning the keypad, do not s rub
the surfa e too hard, and do not pull on
the keys. Doing so may break the keys
or ause the keypad to dislo ate.
• If the BHT or CU be omes smudged, moisten a soft loth with neutral detergent and
wring it out thoroughly. Wipe the BHT or CU with the loth and then go over it
again with a dry loth.
Dust or dirt a umulating on the lear plate of the bar- ode reading window will affe t
reading performan e. If you use the BHT in dusty areas, therefore, periodi ally he k
the lear plate of the bar- ode reading window and lean it if dusty.
• To lean the plate, first blow the dust away with an air brush. Then wipe the plate
with a otton swab or the similar soft one gently.
• If sand or hard parti les have a umulated, never rub the plate; doing so will
s rat h or damage it. Blow the parti les away with an air brush or a soft brush.

• If the BHT fails to read due to spe ular effe ts or other
fa tors, hange the s anning angle of the reading win-
dow or the distan e from odes as shown at right, and
try it again. (Spe ular effe ts o ur when the refle -
tion of the light from the bar ode be omes ex es-
sively strong. This an easily happen when the re-
fle ting surfa e is polished or overed with vinyl.)
• The BHT an read bar odes at a maximum distan e of 40 m (15.7")** from the
bar- ode reading window. (**For details about the s anning onditions, refer to
Appendix A.)
• The bar ode reading pro edure may differ depending upon the appli ation
used, so follow the appli ation's manual.
• 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, align the center of the reading window with
that of the target bar code.
• When you pull the bar-code reading window away from the bar codes, the actual
scanning range will become narrower than the range covered by the illumination
LED.
• The light intensity of the illumination LED will vary depending upon the scanning
conditions and variation of their elements.
1.1 Reading Bar Codes
Turn on the BHT power, bring the bar- ode reading window to the bar ode to be
s anned, and press the trigger swit h. The BHT turns on the illumination LED and
reads the bar ode. Keep the BHT in a position where the bar ode lies within the
illumination range.
When the BHT has read the bar ode su essfully, the indi ator LED will illuminate in
green.
