Compatibility, care & service

  • Check electrical signaling, pinout, voltage, current, connector, mounting and supported firmware before installation; do not rely on matching shapes alone.
  • Inspect physical condition and manufacturer warnings; mains PSUs, CRTs, batteries and spinning media may retain hazardous energy or require specialist service.
  • For vintage equipment, use the correct bus generation, BIOS, driver, media type, cable orientation and resource configuration documented for the machine.
  • Record measured results separately from the manufacturer's published limits and state the setup and measurement conditions.
