Installing the Batteries

Always use AA alkaline batteries, and remember to remove the batteries when your scale will not be in use for an extended period of time to prevent corrosion.
Remove the battery door. Follow the printed icons inside the battery compartment for correct polarity.

Insert the four batteries one at a time with the negative end (-) first so that they depress the spring inside the battery compartment. Gently push the batteries into place until they have fully seated in the compartment.
Replace the battery door by sliding the tabs into the battery compartment parallel to the back of the scale then pressing the door down until it is seated.

Replacing the Batteries

When the batteries are depleted the scale will display the low battery indicator.
Please remove the batteries and replace them with fresh ones as soon as possible.

Using the Removable Tray (#688330 Only)
With the scale placed on a fl at surface, reach underneath the scale with both hands and gently squeeze the two release handles so that they move in an outward direction.

Once the release handles have disengaged, the tray will lift off of the scale platform. The scale is now ready to be used by a standing child or toddler who weighs less than 44lbs.
To reattach the tray, simply align the tray with the scale platform and press down to gently snap it back into place.

Using the AC Adapter (#688340 Only)

The Hopkins Featherweight XL Baby Scale can be powered using either the included four AA batteries, or with the included AC Adapter. Always inspect the AC Adapter to make sure the cord is not cut or frayed and the prongs in the plug and the connector jack are not bent or corroded. For safety, it is recommended to plug the AC Adapter into a surge protector or GFIC outlet.
*Note: The scale will automatically shut off when switching power sources.
The AC Adapter jack is located in the back of the scale

Operating Instructions

2. Press the “ON/TARE” button to turn on the scale. Wait until the scale displays all zeros.

1. When the scale is at zero, press the “RECALL” button to recall the previous reading. Press the “RECALL” button to return to zero.

Change Units
You can toggle the units between Pounds, Pounds & Ounces and Kilograms at any time. The scale will display both active and stored readings in both units.

Tare Function
The Tare Function allows the scale to subtract the weight of an item from the total weight reading, such as when using a blanket or scale liner under the baby.

2. When the scale displays the weight of the item you wish to subtract, press the “ON/TARE” button again and the display will return to a zero reading.

Maintaining Your Scale

Before you use your scale for the first time, and if your scale has not been used for an extended period of time, please check the scale to make sure it is functioning correctly. If you find that your scale is not functioning correctly, please contact Hopkins Medical Products for assistance. Always examine your scale to make sure that there are no obvious signs of damage. Always inspect the AC Adapter to make sure the cord is not cut, abraded, or frayed and the prongs in the plug and the connector jack are not bent or corroded.
Also check the battery compartment to make sure there is no corrosion. If you are not going to use your scale for an extended period of time, please remove the batteries to prevent corrosion (battery compartment corrosion is not covered under the limited warranty.)

Cleaning Your Scale

Follow these guidelines for proper cleaning of your scale. Improper cleaning methods may damage your scale and void the warranty.

• Always remove the batteries and disconnect the AC Adapter before cleaning.

• Never immerse your scale in water or any other liquid.

• Never use isopropyl alcohol or any solvent to clean the LCD display.
  Always wipe with a clean, soft cloth.

• You may clean the external surfaces of your scale with a mild soap and water solution and a clean, lightly damp cloth. Always be sure to keep any liquid from pooling anywhere on the scale. Wipe dry with a clean, soft cloth.

• To clean your scale, you may wipe the external surfaces with SaniZide PRO 1 (available as wipes – Item #695926, or spray bottle – Item #695910) or another hospital-grade disinfectant. Follow the disinfectant manufacturer’s directions for application and dry time. Take care to avoid the LCD screen when using a disinfectant.

Calibration

To perform a calibration, place your scale on a sturdy, level surface and make sure the batteries are installed, or that the AC Adapter power supply is connected. To calibrate your Hopkins Baby Scale you will need two certified 10kg weights. These weights can be purchased through Hopkins Medical Products (Item #685295).

3. Press the “RECALL” key twice. Then press the “ON/TARE” key. The LCD display will show “CAL 10”.

4. Place a 10kg certified weight on the scale.
   

5. The LCD Display will show “CAL 20”.

6. Place a second 10kg weight on the scale.

7. Remove two 10kg weights from the scale.

8. The LCD Display will show “PASS” and then show “20.000” Calibration is complete.

9. Turn scale on again, and weigh the 10kg certified weight to check the calibration for accuracy. If the scale is still out of calibration, repeat the process. If the scale readings remain inaccurate, please contact Hopkins Medical Products. (Contact Info Pg.15)
