SAFETY INSTRUCTIONS ENG Converts the display value into exponential notation, with the exponent as a multiple of “3“ and the mantissa between 0 - 999 (See Page 35) Please read the following instructions carefully before using the calculator. Please keep the operating instructions in a safe place in order to have them quickly at hand, if questions should arise regarding operation.
3. C ALCULATION STEPS AND HIERARCHY Calculations are carried out with the following priorities: 1. Functions 4. +, 2. yx, x y, RpP, PpR 5. AND BASE N mode 3. x, ÷ 6. OR, XOR, XNOR Procedures with the same priority are carried out from left to right, whereby functions in brackets are carried out first. If brackets are nested, the calculations in the innermost brackets are carried out first. 4.
5. CORRECTIONS If you determine an error during entry of the values, you can clear the last number entered with . If you determine an entry error prior to pressing an arithmetic and re-enter it. function key, you can clear this value using In a calculation sequence, you can correct errors in interim results, by carrying it out again using the correct values and then continuing the sequence of calculations where you left off.
7. ENTRY OF CALCULATIONS 7. ENTRY OF CALCULATIONS Calculations can be entered in formula notation (e.g. in algebraic logic). You can enter up to 15 brackets on 6 calculation levels. 7.2) Constant calculations 7.1) Four basis types of calculation (including bracket calculations) EXAMPLE The PROCDURE key must not be used prior to the 16 DISPLAY key.

9. CALCULATIONS WITH FUNCTIONS 9. CALCULATIONS WITH FUNCTIONS The keys for scientific functions can be used as subroutines for the four basic calculation types (including brackets). This calculator utilises the values for π = 3.141592654 and e = 2.718281828 With several scientific functions, the display fades briefly while carrying out complicated formulae. During this time, you should not attempt to enter new values or press the function keys, before the result of the calculation is displayed.

12. BATTERY CHANGE Power supply This calculator uses two power supplies: A solar cell and an alkaline battery (LR43). Change the batteries under the following circumstances As soon as the memory content is cleared. If the display can no longer be read with poor lighting conditions and can not be restored again using the AC key. Precautionary measures regarding the battery Through improper handling, a battery can leak or explode.
12. BATTERY CHANGE 13. DISPOSAL a) Switch the calculator OFF before beginning with the battery change. b) Release the screw on the battery cover on the back of the calculator. (Fig. 1) DO NOT LOSE THE SCREWS! c) Slide the cover in the direction of the arrow and open the battery compartment. d) Remove the empty battery by putting a sharp object into the side indentation in the battery compartment and pressing the battery out. Dispose of the empty battery later, as described under “Disposal”.
