Upgrades

The following Upgrades are available for any Digital Recorder in good working order. Please note, our upgrade voids the factory warranty. If we did not sell the machine with an upgrade installed, we warranty only the parts we put in, not the entire machine. Please contact Doug Oade via E-mail to obtain an RMA number as well as shipping instructions. Prices include return shipping in the 48 states. Please contact us for shipping to other locations.
