The only reason I gave this less than 4 stars, is because it shouldn't take 24 hrs to have the download available. I was surprised to find that I had to wait until the next day to be able to download the manual that I paid for.
The manual itself is the correct manual.

Excellent replacement for original Owner´s Manual. I am totally satisfied!

SERVICE INSTRUCTIONS
For radios that require an open circuit when the microphone is on-hook (such as many Ericsson/GE models), the hang-up logic can be reversed by the following procedure. 1. Open the microphone case by removing three retaining screws. 2. Carefully separate the case halves, taking care not to lose the rubber pieces associated with the cartridge assembly.
3. Add the following components to the PC board assembly at the locations indicated by the highlighted parts in the dash-line parts in Figure 5 and photo in Figure 6.
