8. Troubleshooting by the Checksum

■ Diagnosis of trouble by the checksum is neither reliable nor convenient.

You can only use the checksume of the current direct-view TV to determine whether the software is corrupted or not.
The Checksum value is determined according to the version of the software loaded on the set.
Therefore, you can determine whether the software has been properly downloaded, if you know the correct checksum for that
version of the software.
