What this one means
The appliance and the phone lost each other while swapping credentials. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.
What the code covers

- The same distance and band questions as the rest of this family
What to try yourself
- Restart the appliance's pairing mode and try once more
