Chapter 10: The SOLVER Feature

3. Recalling a Previously Saved Equation

To recall a stored SOLVER equation:

1.  Go to the SOLVER menu, 

and press 

B

 to select the 

B EQTN sub-menu.

2.  A list of saved equation 

names appears in the sub-
menu. Select the equation you wish to call back.

3.  Press 

E

. The stored equation is called back.

 

Note:  Any changes unsaved prior to recalling will be lost. Also be aware 

that any changes to the recalled equation will not be retained 
unless saved manually.
