Chapter 1. Quick Guide
•
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.
• Do not use the BHT near a magnetic body (e.g., equipment that generates a
magnetic field). Doing so will deflect the optical axis of the laser light, resulting
in scanning failure or 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.
