X18S¶

Differences from the X20S baseline this manual is written against:
- Storage — an internal 8GB eMMC by default (an external SD card can be added alongside it), same as the X20 Pro/R/RS — see System Setup → General → Storage location and File Manager.
- Extra trims — like the X20 Pro/R/RS, adds trim switches T5 and T6 beyond the standard four — see Trims.
- Hardware check and the ADC value inspector include the T5/T6 trims in their checks accordingly.
