Factory Reset ST50 Tri Data

[Sam_Steele]

Help. I have a AutohelmST 50 tridata and was going into the calibration menu. I must have pressed the wrong button and it has gone into a loop. Does anyone know how to do a factory reset? As I can't get it out of cal mode
Thanks Sam

Assuming you've tried switching off/on, have you tried pressing either depth/speed or speed/trip for 2 seconds, both of which exit different calibration functions.
The manual, giving more detailed instructions is here
