POTENTIOMETER DESCRIPTION/PROCEDURE
VOLUME Adjusts the audible decimal level for error indication. Power on the printer, place
on-line, and open the print head. When the beep is emitted, adjust the volume
level accordingly.
PITCH Is to be used in conjunction with the configuration adjustments. Make course
adjustments there and then fine tune here. If unable to achieve the desired
setting here, the course adjustment must be reset. Adjust this potentiometer as
labels are being printed. Allow two labels to be printed for each adjustment to
ensure a desired setting.
