Beam Width Adjustment Bar Code
For down-facing reader port model
For forward-facing reader port model
[Handling Precautions]
• The Data Collector is shipped with the laser beam width already
adjusted. So, the laser beam width need not be adjusted. Adjustment is
necessary only when the laser beam does not switch to the correct
position when the beam width is switched.
* Adjustment results are stored in memory.
* Factory settings are returned to if the Data Collector is reset or all
built-in batteries are removed, preventing memory backup.
• If adjustment is not successful, an error message is displayed. If this
happens, retry adjustment.
