The IC-705 is a phenomenal radio, but it is also a sealed, tightly engineered computer. Treat it like a smartphone repair: possible, but difficult without official backing.
The IC-705 is not waterproof. If you drop it in a puddle during POTA, the full service manual provides the resistor and capacitor values needed to trace corrosion on the main PCB.
Users from eHam.net and technical reviewers from bhi Ltd agree that having the "full" service manual is indispensable for anyone performing out-of-warranty repairs or precision adjustments, as the radio's high-density construction makes "guessing" during repairs nearly impossible.

The manual will tell you to connect, open the service software, click "Alignment Mode," and adjust trimmer capacitors virtually via software sliders. Doing this without the manual is impossible.
: For frequencies above 25 MHz, the radio uses a heterodyne converter to down-convert the signal to a 38.85 MHz IF before sampling.
: The 4.3-inch touch screen is the heart of the radio. Use only a soft, dry cloth for cleaning and avoid sharp objects; once scratched, the capacitive sensor can lose accuracy. Quick Technical Snapshot
