Does the Olympus Site License support upgrades from the DS-3300 models?
Yes, the Olympus DS-3300 digital voice recorders use Release 4 license, which is the same as the DS-4000 digital voice recorder. You can combine Release 4 licenses with Release 5 licenses when requesting an Release 5 site license. Verification Source: Digaulle Elhaje, Olympus Product Manager
