Internal Memory Tests

device's internal storage.

The number of bad blocks and the amount of free memory is displayed.

A prompt is displayed to ask whether you want to format the internal memory.

SD Card Tests

The SD Card Tests perform a series of read/write tests on an SD card to verify that
the card is functioning properly.
CAUTION:
POTENTIAL DATA LOSS — This test formats the SD card, which will erase any data
on the card.
Do not use an SD card if it contains data that has not yet been transmitted.
1. Insert an SD card that is not write-protected.
2. Select SD Card Tests.
The tests run and the results display on the screen.
NOTE:
3. If the test fails, replace the SD card and repeat the test.
If the test fails again, the CPU board may need to be replaced. Refer to
"Replacing the CPU Board" on page
56
CAUTION:
POTENTIAL DATA LOSS — Reformatting will erase all data in memory,
including patient data and custom stress protocols. It will not affect the
system software or settings.
Do not format internal memory if you have not transmitted all the patient
data.
If the card is not formatted, an error message will be displayed at the
bottom of the screen. To format a card, insert the SD card and copy data
to the card using the Copy All command from File Manager. The system
will prompt you to format the card. Follow on-screen prompts. Refer to
the operator's manual for details.
