Page 54 in Operating Instructions
The problem is due to the information the user
entered into the printer:
The AGE of the individual is outside the limits built into
the predicted values (for Knudson 3, the limits are age 5
to 83 for males and 87 for females). These can be found
on Pages 54 through 58 of the operating instructions.
Pages 52 & 53 of the operating instructions gives the
formula for calculating predicted values manually.
Or the HEIGHTis entered wrong. You can use either
inches or centimeters, and in using inches the “O” must
go in the first space. Example: Patient is 5 foot 6 inches
tall. Info entered into machine: 066
