A specialized guide on Scribd details internal behaviors like battery protection ICs ( DW01A ) and MOSFETs used in the charging circuit.
For a quick and direct download, Russian forum is a great alternative. It hosts the same Radiomuseum schematic.
Because the external antenna jack connects directly to the RF front-end via a decoupling capacitor, static discharges from outdoor wire antennas can fry the input protection diodes or the LNA transistor. If your radio becomes completely deaf on shortwave but works on FM, check the small SMD diodes located directly behind the antenna input jack.

Static electricity from the whip antenna can blast past the protection diodes and damage the front-end switching field-effect transistors (FETs).
The XHDATA D-808 is celebrated globally by DXers and shortwave radio enthusiasts for its exceptional sensitivity, portability, and value. At the heart of this high-performing digital receiver is a sophisticated circuit design that relies heavily on advanced digital signal processing.

A schematic diagram is an indispensable map when a component fails. Here is how to use it to diagnose common XHDATA D-808 issues: Issue 1: Device Fails to Power On
The XHDATA D-808 is celebrated by shortwave listeners and DXers as one of the best portable DSP (Digital Signal Processing) radios on the market. It offers exceptional sensitivity on FM, LW, MW, SW, and AIR bands, alongside Single Sideband (SSB) capability. Because the external antenna jack connects directly to
Inspect the RF input protection diodes immediately following the external antenna jack.
