1. Enter Rise and Run:
o o 0.
1 0 f 1 i r RISE 10 FEET 1 INCH
1 5 f 5 i R RUN 15 FEET 5 INCH
2. Find Stair values:

s RSRS 16.
s R+/– 0 INCH
s T-WD 12-5/16 INCH
s TRDS 15.
s T+/– – 0-5/16 INCH
s OPEN 12 FEET 2-1/2 INCH
s STRG 18 FEET 0-3/4 INCH
s INCL 31.56°
s RUN 15 FEET 5 INCH
s RISE 10 FEET 1 INCH
s R-HT 7-1/2 INCH
s T-WD 10 INCH
s HDRM 6 FEET 8 INCH
s FLOR 10 INCH
*A in the display means that the calculated riser height exceeds the stored
desired riser height.
