Memory Overflow Errors

NOTE:

Problem:

The random access memory (RAM) space of the Test Set is shared by IBASIC programs and the Save/Recall storage registers. If you have saved a large number of registers in your Test Set, you may encounter a “memory overflow” error when you first attempt to load the Software.

Solution:

You will need to clear up some RAM space by deleting some or all of your saved registers. You can do this selectively (one register at a time) or you can clear all storage registers at once (globally).

Clearing the registers, whether selectively or globally, is permanent. You cannot retrieve the registers once deleted. You have an option to save registers to a RAM memory card, as well. Consult the HP 8921 User’s Guide for instructions on this procedure.

To Clear a Single Register at a Time:

1Press the RECALL key.

2Scroll the cursor to the register to be deleted.

3Press the ON/OFF key.

4Press the YES key (same key) to confirm.

5The register is cleared.

To Clear All Save Registers:

1Press the RECALL key.

2Scroll down to *Clr All* and press the knob.

3Press the YES (ON/OFF) key to confirm.

4All Save registers are now cleared.
