Technical
Reference for Deep Throat Trainer controls, state transitions, calibration, errors, offline behavior, and firmware.
Use this section after the first-session quick start, or when you need the exact meaning of a device state.
| Reference | Use it for |
|---|---|
| Button controls | what a short or held press does on each screen |
| Device states | the startup-to-completion sequence |
| LED and screen feedback | interpreting position feedback without relying on color alone |
| Calibration | first calibration, saved toy data, reset, and recovery |
| Error codes and messages | canonical symptom lookup and first action |
| Offline mode | verified capabilities and unknown persistence limits |
| Firmware updates | update channels, verification, and recovery |
Applicability
Device screens and flows vary by firmware. This reference is reviewed against the dashboard and API source in this repository on August 16, 2026. The DTT firmware repository is not present in this checkout, so firmware-only timing, storage, and version claims are marked as unknown instead of inferred.
