repairs that may not be covered by the warranty. Please observe the following
precautions to insure years of trouble free service from your new scale.
Do not use sharp objects to press any of the buttons.
Do not use the scale if the scale is damaged in any way.
Do not leave patients unattended on the scale.
Do not exceed the scale capacity.
Do not drop the scale.
Do not drop objects on the scale.
When transporting, do not hit other objects, walls or doorframes with the
scale.
Care & Cleaning
With reasonable care, this product will last for many years. Here are some tips to
care for your scale. Failure to comply with these guidelines may void the
warranty.
Hand clean the scale platform and indicator with a moist cloth.
Only clean with a mild detergent.
Do not get water inside the scale.
Do not use strong solvents or abrasive cleaners as this can damage the touch
panel or other plastic parts.
Do not immerse.
Examine the scale periodically for damage and wear and tear before use.
Remove batteries during long periods of non-use.
Installation
Place the scale on a stable flat surface. The scale should rest evenly on all four
feet.

Battery Installation
The DS4500 comes with the ability to take four AA alkaline batteries. These
batteries supply a year’s of typical use with the standard Automatic Shutoff Timer
settings. The standard Automatic Shutoff Timer setting is 10 seconds.
The batteries can be accessed on the bottom of the scale. To access the battery
compartment, turn the scale upside down and open the battery compartment
door. When installing the new set of batteries, be sure the batteries are oriented
properly.

Section 2. Scale Operation
Fig. 2 DS4500 Front Panel
Display Pushbuttons
The Model DS4500 controls consist of FEED, UNIT, REWEIGH, POWER and
ZERO buttons. The display is used to provide weight indications and operator
messages indicating scale operation.
Power On/Off
Press the Power button to turn on and off the scale. The scale has an adjustable
Automatic Shutoff Timer that will power down the scalewhen not in use.
Zero When the zero button is pressed, the scale will be reset to zero weight. This
feature can be used to zero out any weight not desired to be part of the patient
weight.
Unit Press to cycle between lb, lb:oz and kg. The current unit will be displayed to the
right of the weight digits.
Note: Each unit can be disabled individually with the units enable / disable
parameters.
Reweigh
To reinitiate the weighing process, press REWEIGH. This will allow a weighment
to be reinitiated without the patient having to get off the scale platform.
Feed Activates the feed function. See feed function section below.

4
Display Annunciators
The display annunciators will indicate the scale status.
Center of Zero (►0◄)
Indicates that the scale has an accurate zero reading.
Hold Indicates a stable weight has been achieved and held on the display. This
indicates an accurate weight has been achieved.
Low Batt
Indicates when the batteries require replacement.
BEFORE FEED
Indicates the next held weight recorded will be recorded for BEFORE FEED data
string.
AFTER FEED
Indicates the next held weight recorded will be recorded for AFTER FEED data
string.
AMOUNT FED
Indicates the amount of food the baby has retained is displayed and transmitted.

Section 3. Scale Calibration
Multiple Point Calibration
This scale requires multipoint calibration. Do not attempt to calibrate this scale
without using calibrated test weights in the amounts stated below. This calibration
sequence will result in the most accurate calibration possible. CAUTION: Calibrating
this scale improperly will void the warranty and will require field service or return of
the scale to the factory.
1. Turn the scale on by pressing the ON/OFF button.
2. To calibrate in pounds, press FEED. To calibrate in kilograms, press UNIT.
3. Press and hold ZERO and REWEIGH simultaneously.
4. When the display reads Cal 25 lb (CAL10 kg), release ZERO and REWEIGH.
5. Press and hold the FEED button until the display reads CALSP.
6. Press UNIT and the display will read CAL 0.
7. Remove all weight from the scale.
NOTE: During calibration be sure vibration and air currents are not present.
8. Press FEED. The display will count down to zero. The counter will reset if too
much vibration is present.
9. Once the zero calibration is successful, the display will read 10 lb (5 kg).
10.Place 10 lb (5 kg) on the scale and press FEED.
11.When successful, the display will read 20 lb or 10 kg.
12.Place 20 lb (10 kg) on the scale and press FEED.
13.When successful, the display will read 30 lb or 15 kg.
14.Place 30 lb (15 kg) on the scale and press FEED.
15.When successful, the display will read 40 lb or 20 kg.
16.Place 40 lb (20 kg) on the scale and press FEED FEED.
17.When successful, the scale will return to the weigh mode.

8
Calibration Troubleshooting
If Err 0 appears on the display during step 8, the calibration zero is out of range.
Remove all weight from the platform and press FEED to perform the zero calibration
again.
If ErrSp appears on the display during step 10,12, 14 or 16, the span calibration is
out of range. Place the proper weight on the platform and press FEED to perform
the span calibration again.
If scale is unable to calibrate contact Doran’s Technical Assistance department at
630-879-1288.

Section 6. Troubleshooting
General Problem Resolution
Problem
What to Do or Check
Weight reading will not repeat or
scale does not return to zero when
weight is removed.
Person or object other than that being
weighed is touching the scale.
Verify that there is nothing caught in the
feet area or interfering with the feet.
Scale overloads before scale
capacity is reached.
Verify scale calibration is correct. If
problem persists, recalibrate the scale.
Scale will not come to zero when the
ZERO button is pressed.
Make sure that the scale is stabilizing.
After pressing the ZERO button, the scale
should zero as soon as it becomes stable.
Weight readings are not correct.
Verify the scale calibration with an
accurate test weight. If the readings are
not correct, recalibrate.
Be sure the platform is on a flat surface
and all four feet are touching the surface.
Scale drifts off zero.
Check for air currents and/or vibration
around the scale.
