I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.
Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.
5 star quality on these downloadable manuals. Easy to read and all the information is there. A must when doing a custom install or needing to service your precious old school electronics.
