HP15C problem - Mel - 04-26-2006 Hi, Re: HP15C problem - Vieira, Luiz C. (Brazil) - 04-26-2006 Hi, Mel; please, locate the [USER] inscription over the [RCL] key. Because [USER] is printed in yellow (gold?), you should press and release [f] then press and release [RCL] to toggle USER mode on and off. To simplify, we use [f][USER]O.K.? Now locate the [CF] inscriptiopn in blue, in the front, slanted face of the [5] key. Because it is printed in blue, we must press and release [g] then press and release [5] to compose the partial sequence [g][CF] (which stands for Clear Flag). Now press the [8] key and the cannunciator should be turnned off. This sequence is also refered to as [g][CF][8]. This means your calculator is no longer in complex mode, opnly real data and real results are allowed. Now press [g][MEM]and hold the last pressed key for a while ([MEM] is located in the slanted face of the [RCL] key). You should see four numbers, something like this: [ 2 10 0-0 ]This special display tells you how is the HP15C memory organized at this moment. The first number, 2 in this case, is the number of the last available memory register. The maximum possible set for memory registers is the sum of the first and second numbers in the left. In this example, we can set the calculator to work up to register #12. In your case, check what is the second number and compute what you have interms of memory. To change this, please locate the [DIM] function over the [SIN] key and the [(i)] function, over the [COS] key (they are neighbors). As they are printed in yellow... let's consider that you have seen the display shown above when you pressed [g][MEM], so you can set the register size to a maximum of 13, from R0 to R.2 (register #12). Than you can press: 12 [f][DIM][(i)]Now if you press [g][MEM] you'll see: [ 12 0 0-0 ] (based on previous display)Now you can use registers from R0 to R.2. If you do not succed in this (or any other) operation, please post again. Success!

Re: HP15C problem - Karl Schneider - 04-27-2006 Mel -- Well, I certainly couldn't surpass the detail in Luiz' response! I could offer a few insights, however:
