The algorithm used to verify the integrity of the database is based on [http://srecord.sourceforge.net/crc16-ccitt.html CRC16-CCITT], though it's an incorrect implementation.

To obtain the correct value for the checksum, apply the algorithm to the first 0xC81E bytes of the database. This can be done using [https:// | To obtain the correct value for the checksum, apply the algorithm to the first 0xC81E bytes of the database.
