Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!
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.
