Basic Operation

Using Security Functions

Activating the Secure Mode

CAUTION Once you activate secure mode (by pressing Confirm), you cannot deactivate or decrease the security level; the erasure actions for that security level execute at the next power cycle. Once you activate secure mode, you can only increase the security level until you cycle power. For example, you can change Erase to Overwrite, but not the reverse.

After the power cycle, the security level selection remains the same, but the secure mode is not activated.

Press Utility > Memory Catalog > More (1 of 2) > Security > Enter Secure Mode > Confirm. The Enter Secure Mode softkey changes to Secure Mode Activated.

If Your Instrument is Not Functioning

If the instrument is not functioning and you are unable to use the security functions, you may physically remove the processor board and hard disk, if installed, from the instrument. Once these assemblies are removed, proceed as follows:

For removal and replacement procedures, refer to the Service Guide.

Processor Board

Either

•Discard the processor board and send the instrument to a repair facility. A new processor board will be installed and the instrument will be repaired and calibrated. If the instrument is still under warranty, you will not be charged for the new processor board.

or

•If you have another working instrument, install the processor board into that instrument and erase the memory. Then reinstall the processor board back into the non- working instrument and send it to a repair facility for repair and calibration. If you discover that the processor board does not function in the working instrument, discard the processor board and note that it caused the instrument failure on the repair order. If the instrument is still under warranty, you will not be charged for the new processor board.

Hard Disk

Either

•Discard the hard disk and send the instrument to a repair facility. Indicate on the repair order that the hard disk was removed and must be replaced. A new hard disk will be installed and the instrument will be repaired and calibrated. If the instrument is still under warranty, you will not be charged for the new hard disk.

or

•Keep the hard disk and send the instrument to a repair facility. When the instrument is returned, reinstall the hard disk.
