The "MODE" key switches between DEG, RAD, nd GRAD.
The SUM key adds values to the summation registers and displays the
number of values entered so far. It is unclear how the summation
registers can be cleared other than by turning the unit off.
Inside the plastic cover the function of the red "INV" key are described:
| INV SUM |
DELETE |
Remove value from summation registers. |
| INV sin, cos, tan |
arcsin, arccos, artan |
Inverse trig functions. |
| INV EXP |
CN |
? |
| INV MR |
sigma |
Standard deviation of SUM values. |
| INV STO |
mean |
Mean of SUM values. |
| INV M+ |
variance |
Variance of SUM values. |
