Approved analyzer manufacturers, are required to submit software changes for the following reasons:

1. To correct software errors discovered during field use.
2. Due to legislative or regulatory changes in the I/M program.

Analyzer manufacturers shall submit all software changes for approval and must obtain written State approval prior to use of the software for Official State Inspections. The version number shall consist of a four (4) digit numeric code to be made up of the current year and a two-digit version number. Example: the software version code for the first version in 2006 would be "0601". Every software update submitted to the State shall cause the software version number to change upward.

NOTE: All analyzers must have their new software installed within 65 days from the Software Approval Date. DMV has the right to lockout any analyzer beginning on the 66th day for not having the most current software installed.
