For forward-facing reader port model
[Handling Precautions]
• The Handheld Terminal 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 resumed if the Handheld Terminal is reset or
all installed batteries are removed causing memory backup not to
be performed.
• If adjustment is not successful, an error message is displayed. If this
happens, retry adjustment.
