1.0 Introduction
The Rice Lake Digital Handrail Scale is designed for weighing bariatrics and ensures sound, accurate weighing
information. A non-skid platform paired with side rails assists persons who need extra support and safety. The
scale is set up to use motion sensing weighing technology, to determine the actual weight of a moving patient.
The weight is displayed on the indicator and can be displayed in pounds or kilograms.

Important
Caution
Warning
DANGER
Indicates an imminently hazardous situation that, if not avoided, will result in death or
serious injury.
Indicates a potentially hazardous situation that, if not avoided, could result in death or
serious injury.

Before attempting to operate this unit, make sure every individual who operates or works
with this unit has read and understands the following safety information. Please follow
these instructions carefully.
• Do not drop the scale or subject it to violent shocks.
• For accurate weighing, the scale must be placed on a flat, stable surface.
• Do not transport the scale while someone is standing on it.
• Weight exceeding the maximum capacity (1000 lb/453 kg) may damage your scale.
• Operating at voltages and frequencies other than specified could damage the equipment.
• If the LO Bat indicator activates, for accurate weighing, replace the batteries or connect the scale to an AC
power source as soon as possible.
• To avoid cross contamination, the scale should be cleaned regularly.
• Avoid contact with excessive moisture.
• Do not allow minors (children) or inexperienced persons to operate this scale.
• Do not jump up and down on the scale.
• Do not use in the presence of flammable materials.
• Do not make alterations or modifications to the scale.

3.0 Scale Assembly
3.1 Unpacking Your Scale
Place the unopened box in an open area that has ample room for unpacking the scale.
Parts contained in the shipping box include:
• The scale
• This manual
• 6 mm Allen key
3.2 Repacking
If the Digital Handrail Scale must be returned for modification, calibration or repair, it must be properly packed
with sufficient packing materials. Whenever possible, use the original carton when shipping the scale back.
Important
Damage caused by improper packaging is not covered by the warranty.
3.3 Setting Up Your Scale
Move the scale into the area where the weighing process will occur. Place the scale on a hard, level surface for
the most accurate weighments.
1. Locate the operator’s manual from inside the box and set aside as it will provide instructions on the
proper set up.
2. Using two people, remove the scale out of the packaging material that it came in by lifting the scale out
of the box by the scale base.
Caution
DO NOT lift the scale out of the box by its handle as this can cause the hinges to break.
3. Gently set the scale platform down to the floor.
4. Loosen the handles using the Allen key and unfold handles and set upright.
Lift handles up
Figure 3-1. Set Up Sides to a Vertical Position
5. Adjust the feet to ensure that the base of the scale base is not touching the floor.
6. Screw in all four legs.
7. Attach the wrap around rails.
8. Tighten the hex screw head using the enclosed 6 mm Allen key to stabilize the scale.

4Digital Handrail Scale Technical & Operating Instructions
Inserting Batteries
The six AA batteries that come with the scale offer an average of 25 hours of continuous use.
To install the batteries,
1. Open the battery chamber cover by loosening the thumbscrew.
2. Insert batteries into the battery chamber as shown in Figure 3-2.
Figure 3-2. Battery Chamber
3. Close the battery chamber.
If an external power supply or USB power supply is connected, the battery flag on the display is turned off.
When using battery or USB power supply, the backlight power is deducted to 60%.
AC Power Connections
Use the optional 120 VAC or 230 VAC adaptor when power is available. The optional AC power adaptor plugs
into the back of the indicator as shown in Figure 3-3.

LB/KG
Print
Print
LB/KG
Print — A long key press will send data out from the RS-232 port.
LB/KG — A short key press allows the user to toggle between kilograms
and pounds providing that it’s enabled in configuration mode.
There is no toggling while in the BMI mode.
Zero
Zero Clears the weight off the scale and returns it to zero after three seconds.
It works only if the current weight is stable and zero up to 2% of full weight.
Hold
Release
Hold
Release
Hold & Release — The first press holds the most current weight value shown
on the display.
A second press releases the weight value shown.
This key is not active while in BMI mode.
BMI
BMI Enables the user to access the BMI (Body Mass Index) function. This key
only works if there is a locked weight shown on the display and the BMI
function is turned on in the configuration mode.
TARE
T
TARE Used to subtract the weight off the scale, example: oxygen tank, other
equipment.
CLEAR
CLEAR Allows the user to return to normal weighing when the BMI value is being
displayed.
While in BMI mode, the height display causes the value to return to the
default of 190.0 cm, 5 ft, 7.5 in.

6Digital Handrail Scale Technical & Operating Instructions
Caution
The keys on the front panel display are very sensitive so only a gentle pushing motion is required to
obtain results.
The scales have the capability of performing different operations beyond just calculating weight. The various
operating instructions are described below.
4.1 Weighing
Use the following steps to weigh a person.
1. Press the On/Off key to turn on the scale and 0.0 will appear on the display along with ZERO on the upper
display.
2. When the person step on the scale the display shows the person’s weight. The LOCK annunciator is on in
the upper display and beeps to indicate the end of the weighing process.
3. To change the display from kg to lb and vice-versa, press the LB/KG key.
4. To turn off the scale, press and hold the On/Off key until OFF appears on the display.
4.2 Hold/Release Function
Use the following steps to use the Hold/Release function.
1. When the person is on the scale, press the Hold/Release key.
2. When the person steps off the scale, the weight and the HOLD & LOCK annunciator will remain on the
display.
3. At this stage the Zero key will not work. The only way to return to zero from here is to press the Hold/
Release key one more time.
Note
Pressing the Hold key prior to a person getting on the scale will also work.
4.3 Preset Tare
Use the following steps to use the Preset Tare.
1. When the weight is set to 0.0, place the extra load on the scale. Press the TA RE key until the display
returns to 0.0 and NET appears on the display.
2. Remove the extra load from the scale. The weight will appear with a negative symbol to the left of it.
3. Ask the patient to step on the scale with the extra weight. The display shows the patient’s weight. The
NET annunciator is still on. The weight of the extra load remains stored in memory.
4. To cancel the tare weight, press and hold the TARE key until NET disappears from the display and the
display turns back to 0.0 and GROSS appears. Tare weight is also cancelled when the scale is turned off.
ENTER Used to accept height in BMI mode.
Accepts the value of the parameter last entered and moves to the next stage.
A long press of the ENTER key during the scale’s start up process will enter
the ID display (pre-parameter mode).
Up/Down Arrows Used to adjust height input (0.5 in/0.5 cm) while in BMI mode.
Adjusts the value of the flashing digit/number.
