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 [^]
