We have received a lot of enquiries for the English modification guides of various equipment. In general the answer is: please read these pages carefully and often, all information will appear here as soon as we get it. Please remember that most software and guides are and will be for phones that were manufactured for the Scandinavian NMT networks. The modification guides may help you to modify equipment manufactured for your local networks, but the software will not possibly work in other versions. If you need more specific info, please keep your enquiries within the following guide lines:

This will help us to process your enquiry in a comparatively short time. Please remember, though, that the English feedback channel is operated by only a handful of voluntaries who often have more urgent and important duties.

If you are interested in software design, we can send you the OH5NXO source code package. Just contact us.
