RL-DBS-2 Dual-Range Digital Baby Scale

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 a spontaneous movement of the baby and the weight can be displayed in pounds/ounces or in kilograms.

1.1 Safety
Safety Signal Definitions:

****DANGER Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. Includes hazards that are exposed when guards are removed.
****WARNING Indicates a potentially hazardous situation that, if not avoided, could result in serious injury or death. Includes hazards that are exposed when guards are removed.
****CAUTION Indicates a potentially hazardous situation that, if not avoided, could result in minor or moderate injury.
IMPORTANT Indicates information about procedures that, if not observed, could result in damage to equipment or corruption to and loss of data.

General Safety

Do not operate or work on this equipment unless this manual has been read and all instructions are understood. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any Rice Lake Weighing Systems dealer for replacement manuals.
****WARNING Failure to heed could result in serious injury or death.
Ensure every individual operating or working with this unit has read and understands the following safety information.
Do not transport the scale with an infant on the weighing tray.
Clean the scale regularly to avoid cross-contamination.
Do not allow minors (children) or inexperienced persons to operate this scale.
Do not use in the presence of flammable materials.
Do not use this product if any of the components are loose or cracked.
Do not drop the scale or subject it to violent shocks.
For accurate weighing, the scale must be placed on a level, stable surface.
Weight exceeding the maximum rated scale capacity may damage the scale.
Avoid contact with excessive moisture.
Do not make alterations or modifications to the scale; any alterations void the warranty.
For accurate weighing, verify the proper setup is complete prior to first use. See Section 3.2 on page 4.
Operation at voltages and frequencies other than specified could damage the scale.
Utilizing adapters not supplied by Rice Lake Weighing Systems voids all warranties.

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.

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.

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.
