INTRODUCTION

The Model 6745 Baby Scale is a 30 pound (15 kilogram) capacity, battery-operated baby scale
housed in a painted steel enclosure. The scale is equipped with a removable baby tray and a
color coded membrane keyboard. The Model 6745 has a number of special features that make
it both easy to use and maintain. This manual contains information on the operation of the
scale. Please take time to read the manual before using your new Model 6745.

QUICK START

Although it is recommended that you read this manual before attempting to operate the scale,
this section is included to provide a condensed set of instructions on installing and using the
scale. At a minimum, please make certain you read all of the caution and warning statements.

Step 1 Install the baby tray by sliding the baby tray onto the weighbridge. Make sure the

release knob “clicks” and locks the tray in place.

INSTALLATION

Unpacking

Begin the installation by removing your new Model 6745 Baby Scale from the shipping carton.
Examine the scale and baby tray for any damage that may have taken place during shipment.
If you find evidence of shipping damage, the shipping company should be contacted at once. It
is a good idea to keep the scale shipping carton and packing material for later use should
storage or transport of the scale become necessary.

Level Adjustment

Check to make certain the scale is level. The level indicator is located in the center of the
weighbridge under the baby tray. Remove the baby tray and observe the level bubble (see
Figure No. 1). If the scale is not level (the bubble will not be centered), loosen the locking nut
on all four (4) mounting feet (see Figure No. 2) and adjust them as required to center the
bubble and attain a level scale. Once a level condition has been obtained, lock the mounting
feet in place by tightening the adjustment nuts against the bottom of the scale.

Step 1 Place the scale on a table top.
Step 2 Position the baby tray onto the weighbridge.
Step 3 Slide the baby tray onto the weighbridge until you hear the release knob “click”.
Step 4 Verify the baby tray is locked in place by making certain that it cannot be slide to

the left or right.

WARNING! Make absolutely certain that the baby tray is locked in place before
using the scale. Be sure that the locking knob is in the locked position. Failure
to lock the baby tray in place can result in serious injury to the baby should
the tray separate from the scale.

INSTALLATION, CONT.

Battery Installation

The 6745 Baby Scale can use 6 "C" size Alkaline, Ni-Cad or NiMH batteries (not included). If
you wish to operate the scale from batteries, you must first obtain and install batteries before
operations can begin. The batteries are contained in a battery holder inside the scale. Access
is via a removable panel on the bottom of the scale.

The scale can operate for 200 hours of continuous use when using alkaline batteries or with
fully charged Ni-Cad or NiMH batteries, 50 hours of continuous use.

NOTE: When using Alkaline batteries, make sure the niCAd setup option is disabled (set to

0). Refer to Setup and Calibration or Setup Review.
Use the following procedure to install the batteries.

Step 1 With the baby tray installed, turn the scale upside down on a stable surface.
Step 2 Locate the rectangular panel on the bottom of the scale and remove the thumb

screw retaining it.
Step 3 Remove the panel (lift straight up and slide it out) exposing the battery holder.
Step 4 Install 6 "C" size batteries in the holder, making certain they are positioned in

accordance with the polarity markings located in the battery holder. Refer to Figure

No. 4.
Step 5 After placing all 6 batteries in the battery holder, replace the panel on the bottom of

the scale (slide the tab in the slot on the scale) and install the thumb screw.

Step 6 Turn the scale over and press the ON key.
Step 7 If the display turns on, the batteries have been installed correctly. If not, turn the

scale over, remove the panel and check for one or more improperly positioned

batteries.

The 6745 Baby Scale can be operated from a power supply or from Alkaline,
Ni-Cad or NiMH batteries. All six (6) batteries must be of the same type. They
must all be Alkaline, all Ni-Cad or all NiMH. DO NOT mix Alkaline and Ni-Cad or
NiMH batteries. The power supply is also used to recharge the batteries, when
the scale is operated from Ni-Cad or NiMH batteries. DO NOT connect a power
supply to the scale if using alkaline batteries.

INSTALLATION, CONT.

Low Battery Indicator

When the batteries are near the point they need to be replaced (Alkaline) or recharged (NiCad
or NiMH), the low battery annunciator on the display will turn on (see Figure No. 5) If the
battery voltage drops too low for accurate weighing, the scale will automatically shut off and
you will be unable to turn it back on.

If using Alkaline batteries when the low battery annunciator turns on, turn the scale off, remove
the old batteries and replace with new ones. Follow the same procedure for installing batteries
when battery replacement becomes necessary.

If using NiCad or NiMH (and the niCAd setup option is enabled, set to 1 or 2), plug the power
supply into the scale and then into the proper electrical wall outlet. The scale will begin
charging the batteries.

Battery Status

If batteries are used, the scale will show the battery status on power up. The display will show
bAttry then change to ð YY ð, where YY indicates the remaining battery voltage expressed
as a percentage (%) of the total battery voltage.

Battery Charging

To recharge the Ni-Cad or NiMH batteries, the power supply must be connected to an AC
power outlet and plugged into the scale. It will take approximately 15 hours to fully recharge
the batteries in the scale. While the batteries are charging the scale can still be operated. Note
that charging the batteries for more than 15 hours will not damage them.

When the scale is to be turned off, pressing the OFF key once will display “dashes" scrolling
across the display indicating the batteries are being charged. Pressing the OFF key again, will
display OFF and turn the scale off. If the power supply is disconnected before the 15 hours, the
scale will continue to charge the batteries when the power supply is plugged back in. Note that
the auto-shutdown feature (if enabled during setup and calibration) will be disabled when the
scale is charging the batteries.

NOTE: When the scale is turned off, it is NOT charging the batteries.

Placing the Scale

After the batteries have been installed, the scale may be prepared for use. Place the scale on
a stable, vibration-free level surface away from direct sunlight and from any rapidly moving air
source (heating/cooling vents, fans, etc.). Make certain the power cord and peripheral cables
are routed out of the way of normal traffic. If the scale is unstable, adjust the front legs up or
down as necessary until the scale is stable.

WARNING! Make certain that the structure beneath the scale is of sufficient
strength to hold both the scale AND the maximum load to be placed on the
scale. Failure of the supporting structure can result in a serious injury to the
baby in the baby tray, as well as damage to the scale.

Installation of the scale is now complete. Please read the operating instructions contained in
this manual before attempting to operate your scale.
