DS4800 OM QUICK GUIDE

The DS4800 OM is completely software controlled and software programmable through Genius™ which allows

adjusting the oscillating frequency and the minimum and maximum oscillation angles of two separate reading

zones.

When the oscillating mirror is programmed to read barcode labels at small angles, position the reader to

assure

at least 15°

for the Skew angle. This angle refers to the most inclined or external laser line, so that all other laser

lines assure more than 15° Skew. This avoids the direct reflection of the laser light emitted by the reader.

Otherwise, the scanner can be mounted at an angle of inclination of 15° in order to attain symmetrical deflection

ranges.

In the above case, the zone where the scan line is perpendicular to the reflecting surface corresponds to a neutral

zone at the center of the reading field.

NOTE

By limiting the raster width to the minimum necessary, the number of scans on the reading

surface is increased.
