Denso BHT-6000 - Manual (Page 17)

• When reading bar codes, slightly tilt the
BHT-6000 down towards you relative to
those codes, as illustrated at right.
• If the BHT-6000 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-6000 can read bar codes at a maximum distance of 24
cm (9.4") [35 cm (13.8") for the BHT-6000D]** 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.)
• The bar code reading procedure may differ depending upon the application
used, so follow the application’s manual.
• Before reading labels, clean them if stained.
• Avoid using the BHT-6000 in direct sunlight. The BHT-6000 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.
• The further you pull the bar-code reading window away from bar codes, the
wider the quiet zones required, in relation to bar code lengths in the illumination
range covered by the illumination LED.
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 M1 or M2 key (Magic key 1 or 2)*. The BHT-6000 lights the
illumination LED and reads the bar code.
When the BHT-6000 has read the bar code successfully, the reading confirmation LED
will illuminate in green.
