1.0 Introduction
The Rice Lake Dual-Range Digital Baby Scale (RL-DBS-2) provides precise weighing of babies for accurate, reliable and
repeatable weighments. Movement compensation technology eliminates errors caused by spontaneous movement of the
baby and the weight can be displayed in pounds/ounces or in kilograms.
Manuals and additional resources are available from the Rice Lake Weighing Systems website at www.ricelake.com/health

2.0 Setup
The RL-DBS-2 comes fully assembled and includes the scale and a 120 V or 230 V AC adapter. Immediately after unpacking,
visually inspect the RL-DBS-2 to ensure all components are included and undamaged. If parts were damaged in shipment,
notify Rice Lake Weighing Systems and the shipper immediately.
Use the following instructions for scale setup:
1. Place the scale on a sturdy, level surface.
2. Connect the 120 V or 230 V AC adapter to the back of the scale.
3. Plug the AC adapter into a power source.
Figure 2-1. AC Power Connection Site
The RL-DBS-2 can also be powered by four AA alkaline batteries if an additional power source is not available. A battery
powered scale automatically turns off after two minutes of not being used to save battery life. Replace the batteries or connect
to an AC power source as soon as possible if the low battery indicator (Lo) displays.

3.0 Operation
The RL-DBS-2 accurately weighs babies up to 44 lb (20 kg) and features a dual-range capacity for increased precision from
0-22 lb (0-10 kg). The weighing surface also includes a ruler for measuring the length of the baby. The built-in ruler can
measure babies up to 22.5 in (57 cm).
If the scale is battery powered and has not been used for two minutes, it automatically turns off to save battery life.
