11.6 User initiated 'self-test' routine'

At any point during normal operation, the XD One can run the 'self-test' routine to ensure system
functionality.
To perform a 'self-test', press and hold the power button until all three function icons are blue, at
this point, release the power button and the device will initiate the 'self-test' sequence.
'Self-test' results
After the self-test routine has been performed, the XD One will indicate the result via illuminated
icon status.
Refer to section 11.2 for "Pass"/"Fail" illumination details.
Note: On return of a "Pass" result, the XD One will automatically continue with sensing operation.
On return of a "Fail" result, the XD One will check if the fault is recoverable and repeat the 'self-
test'. This will take place up to a maximum of four times before the device will return a fatal error
indication. In the unlikely case of fatal error indication, it is recommended to contact the Trolex
service team.
