​Hello,

The "402WT" field (5 characters) contains the truncated commercial product name.

The "K839" field (4 characters) contains

�? The "K" field (1 character) contains the last character of the assembly plant identifier

�? The "8" field (1 character) contains the last digit of the year of manufacture.

�? The "39" field (2 characters) contains the assembly week code.
