Manuals:

As long as the Quantar and Quantro are current Motorola products, most of the later manuals are still available for purchase. The prices listed below should be taken only as a rough guideline. Motorola adjusts prices quarterly, and offers one set of prices to their dealers / service shops, another on their order desk, and a third to self-maintaining fleet customers (i.e. police departments, fire departments, etc).

As of April 2011 the available Quantar manuals are:
