Chapter 3 Scanning Codes

Operating procedure
(1) Bring the reading window to a target code and press the trigger switch. Pressing the
trigger switch halfway emits a laser light (marker) to indicate the scanning range. Align
the center of the marker with that of the target code.
Pressing the trigger switch fully turns on the illumination LED and scans the code.
(This step is not required in the continuous reading mode 1, 2 and auto sense mode.)

indicated by the marker
(2) When the scanner has read the code successfully, it turns on the indicator LED in blue and
beeps.
NOTE: The actual scanning range is narrower than the marker range. The scanning range
is approx. 2.4" (6 cm) wide by 1.6" (4 cm) high when the scanning distance is approx. 3.9"
(10 cm).
NOTE: Allow only a single code to come within the scanning range. If two or more codes
lie within the scanning range at the same time, the scanner may fail to read or continue
reading those codes alternately.
NOTE: The scanner can read codes omnidirectionally. Note that a target code plus its
margin should lie within the scanning range.
NOTE: If the scanner fails to read due to specular effects or other factors, change the
scanning angle of the reading window or the distance from codes, and try it again.
(Specular effects occur when the reflection of the light from the label surface becomes
excessively strong. This can easily happen when the reflecting surface is polished or
covered with vinyl.)
NOTE: The marker range should be used merely as a guide. It does not assure that a code
within the marker range can be read.
