-OPERATING MANUAL-
 Emerald scales only differ in weighing units and capacity. Unless
otherwise specified, the content of this manual applies to all models.
 For best results, use the scale in the specified optimum operating
temperature.
 For best accuracy, perform your mass measurements in clean
environments, free of electrostatic and magnetic fields, dust and dirt,
moisture, vibration and air currents.
 Use your scale with care, gently loading items to be weighed onto the
center of the pan. Avoiding rough treatment will aid in the life of your
hand-held scale.
 Calibration weights are not provided with the scale.
