Before using the scale, it must be balanced (zeroed). To zero the scale, perform the following:
1. Place the scale on a level, stable surface.
2. Referring to the illustration, move both poises to zero.
3. Locate the BALANCE SCREW on the left end of the beam and turn it in or out as
required, until the BEAM POINTER is in the center of the opening in the TRIG LOOP.
4. The scale is now ready for operation.

459-CH OPERATING INSTRUCTIONS
1. Place the scale on a level, stable surface.
2. With the child seat empty, move both poises to the Zero position. Be sure the BEAM
POINTER is in the center of the opening in the TRIG LOOP.
3. Slide the LARGE POISE to the approximate weight of the child. I.E. If the child weighs
approximately 25 pounds, slide the LARGE POISE to 25 pounds.
4. Lay the child being weighed in the center of the seat. This will distribute the weight
evenly across the scale.
5. Slide the SMALL POISE to the middle of the beam (between 2 and 3 pounds).
6. Continue sliding the SMALL POISE until the BEAM POINTER is centered in the TRIG
LOOP opening.
7. Read the SMALL POISE at the pointer and add to the weight from the LARGE POISE.
I.E. If the LARGE POISE is at 25 pounds and the SMALL POISE is at 4 pounds, 6
ounces, the child weighs 29 pounds, 6 ounces.
Do not leave the child unattended in the child seat. Failure to
maintain continual control of the child can result in serious
injuries should the child fall from the child seat.
NOTE! The seat straps have been intentionally omitted!
