### Machine wont power on, cord and power going to it are good.

Could be a bad power supply or bad function board. EBM has both parts available 800-832-6522. You would have to remove plastic cover over the function board and check for voltage on the wires from the power supply (where the on/off switch is to the function board. If no dc voltage is present at function board, then power supply has failed. Power supplies are wearing out due to age.

### How to use the exp key

I think it is case of mistaken identity. There is a function called the power function. The general form of it is a*(b)^x or a times (b) to the power of x. a is just a constant factor (not equal to 0) and b is the so-called base ( also different from zero). Personnally I call this function the power function, but you find it is often called the exponential function.
The exponential function e^x is similar to the power function. The main difference is that its base is a certain irrational number called e (=2.718281828...).
What you want to do, as far as I can guess is to calculate 2000*(1+0.12)^20.
Simplify your life and set 1+0.12 as 1.12, and type in 2000 [*]1.12^20=
1.12^20=9.646293093. Multiplied by 2000, this gives you a final result 19 292.58
To enter the the power use the key marked as [X^y], [Y^x] or [^]
