HP 35s Introduction to the training aids

Calculator Settings and Resetting the Calculator

The training aids assume that the HP 35s modes and settings are as they would be when a new HP 35s is turned on the

first time. Changes to these settings needed for examples are described in the training aids. After some examples have

been worked through, the HP 35s settings might be very different from the original ones. A quick way to return to the

standard settings is to perform a MEMORY CLEAR, but note that this will clear all of the calculator memory.

Press and hold down the

key, then press and hold down the

key as well, and press the

key. Now

release all three keys, and the display will show MEMORY CLEAR to say that everything has been cleared from the

calculator memory, and all settings have returned to their original values. DO NOT DO THIS IF YOU WANT TO KEEP

ANY PROGRAMS, EQUATIONS OR DATA THAT ARE IN YOUR CALCULATOR. If you want to keep what is in memory

but return the settings to their original values, you will have to change the settings one by one.
