Introduction 1
1.0 Introduction
The RL-650 Series Neonatal Scale provides precise weighing of infants and neonates. The scale is equipped with
Motiontrap™, a special motion sensing weighing technology, which compensates for involuntary movement caused
by an active infant. The infant’s weight can be displayed in pounds/ounces or in kilograms/grams. The weight is
displayed until reweighing is performed or until the scale zeros out.
There are precautions that must be taken to prevent injury to the baby and damage to the scale. See Section 1.2 on
page 2.
Follow all instructions for installation and usage, included in this manual. The manufacturer is not responsible for
any damage or injury from incorrect operation or manipulation by the user.
