Page 5: Section 1: Installation
The Model 25 Olympic Smart Scale is an electronic baby scale attached to a roll-around mobile base. Calibration Check Every Smart Scale is calibrated at the Olympic Medical factory before shipment. However, the calibration of the scale should be checked before it is put into service. (See Calibration instructions on page 3-1.)
Page 6: Instructions For Cart Mounting
Installation Instructions for Cart Mounting CAUTION: When using the scale on a cart, ensure that it is securely anchored. Four threaded (10-32 UNF) holes are provided in base plate of scale for bolting it to a cart or table (Fig. 1B). Rubber feet do not have to be removed.
Page 7: Initial Battery Charge
Installation 2. Lift tray straight up (Fig. 1D). Tray Tray Feet (4) Tray Mounts (4) Fig. 1D To attach the tray: 1. Lower tray so four feet fit into tray mounts. 2. Securely tighten all four Phillips screws (Fig. 1C). Initial Battery Charge The Smart Scale has an internal rechargeable battery pack that automatically charges when it is connected to a wall outlet.

(Ounces to 0.1 ounce.) 2 Reweigh: Press to weigh the baby again (after initial weighing is completed and green “Read”...
Page 11: On/Off
Operation On/Off Press On/Off (see Fig. 2A) to turn the Smart Scale display on or off. When the Smart Scale display is on, the “Standby” light blinks for a few seconds while the scale warms up and automatically zeros. Wait for the “Standby” light to dim and “0” to appear on the weight display before placing the baby on the scale.
Page 12: Setting Caster Brakes (Model 25)
Operation Setting Caster Brakes (Model 25) The front two casters have foot brakes. Step on one side of the brake lever to set the brake. Step on the other side to release (Fig. 2D). CAUTION: Always lock casters before placing baby in the tray.
Page 13: Baby Moving
Operation Baby Moving If the baby is moving, the Smart Scale will automatically compute the weight within a few seconds. During this time, the yellow “Averaging” light will blink and the beeper will sound. NOTE: You can adjust the sound using the On/Off Volume Control knob, which is located below the control panel to the right (see page 2-3).
Page 14: Tare Function
Operation Tare Function There are two ways to cancel (tare out) the weight of blankets or other objects: If the scale display is on (“0” shown on the display), place blanket on tray and press Zero. The blanket weight will be If an object is on the tray cancelled and the display will show weight of baby without the and the display shows “0”,...
Page 15: Cleaning
Operation Cleaning CAUTION: Do not allow liquid to enter the case as this may damage the electronics and provide an electric shock hazard. CAUTION: To avoid damage to tray, do not wipe with alcohol. Regularly wipe the Smart Scale clean using a cloth dampened with any ordinary hospital disinfectant.

(PCB) level. These instructions will assist you in isolating the problem PCB or component. The faulty PCB must then be returned to Olympic Medical for repair or replacement. If the loadcell is found to be damaged, return the scale to Olympic Medical for repair.
Page 18: Calibration Procedure
Service Calibrate Before First Use: The Smart Scale was calibrated at our factory in Seattle before it was shipped. However, it should be calibrated before being put into service because local variations in the force of gravity can affect calibration by as much as 20 gm. Calibration Frequency: Smart Scale calibration should be checked , at minimum, every 12 months as well as each time after a tray is changed.
Page 19: Off-Center Load Test
Service Fig. 3D 4. Perform the off-center load test. Off-Center Load Test Do the following to check the accuracy of the load cell after calibration: 1. Place the 7500-gram test weight in the center of the tray and press Reweigh. Record the displayed weight. 2.
Page 20: How Olympic Smart Scale Averages The Weight Of An Active Baby
Service How Olympic Smart Scale Averages the Weight of an Active Baby The Olympic Smart Scale uses a sensitive loadcell together with a proprietary software algorithm to detect the most accurate weight and motion of an infant. When weight-force is applied to the tray, electronic signals from the loadcell are processed by a series of electronic filters and a microprocessor to detect motion and determine averaged weight.
Page 21: Disassembly
Disassembly on page 3-5 and then follow the instructions in Problems & Solutions on page 3-9. If the loadcell is damaged, return the scale to Olympic Medical for service. After identifying a problem PCB, see Removing Internal Compo- nents on page 3-12.
Page 22 Service 3. For Model 25 scales, open door on base and remove the four screws securing the scale to the base (Fig. 3G). Lift back of scale and slide scale backwards until the Volume Control Knob clears the front of the skirt.
Page 23 Service 6. Remove the eight screws around the lower edge of the case (Fig. 3I). Phillips Screws (8) Fig. 3I 7. Ensure that the ribbon cable is still connected to the display. Carefully lift off the upper case and rotate it 180º, pivoting around the ribbon cable in the front.

Page 25: Problems & Solutions
Service Problems & Solutions Schematics, wiring diagrams, and PCB drawings are at the back of the manual. Use the troubleshooting measurements described below to test printed circuit boards and components that are suspected of being defective (see Troubleshooting on page 3-17). Before conducting troubleshooting measurements on the Smart Scale, do the following: 1.
Page 26 Service Scale does not turn on and “Standby” does not blink. On main PCB, U1-1 should go logic low when On/Off is pressed. 1. If it does not go low: a. Test the membrane switch panel. Replace if defective. b. Test display PCB ribbon cable. Replace if defective. 2.
