Memory Board

The memory board contains the software that operates the ventilator. The memory board
should need to be replaced only when upgrading the software to a new version. It is a
generally a good practice to upgrade the ventilator software to the most current released
version at the time the ventilator is being serviced. This will ensure the advantage of all new
features and reliability improvements.
CAUTION
Software Version– Never install a version of software lower than the version originally
installed. Erroneous operation may result from the installation of incompatible software.

Generally, LTV ventilator software is designed to be backwards-compatible.
