Diagnostics
High The NOxBOXiperforms self-tests at start-up and during operation
to ensure safe performance is maintained. In the event that a
critical test fails, the system will display a full-screen notice
indicating that the system can no longer be used safely.
Press the on screen reset button.
Sensor Bias Lost The Nitric Oxide sensor requires a constant very low trickle charge
to maintain its calibration. In the event that the system is not
stored on mains power charge, after an extended period of time
the battery may completely discharge and the sensors will lose
their calibration bias.
In the event of power loss, connect the unit to mains power
and allow 6 hours for the unit to charge before
calibrating the NO sensor and re-commissioning the unit.
If another system is not readily available and patient
requires therapy, engage the manual override mode, replace
the system as soon as practically possible and alert the
Service Engineer.
The Nitric Oxide sensor is sensitive to extreme temperature
variation, contact with VOCs (such as alcohol based cleaning
products), strong fragrances, direct contact with moisture or
vibrations (such as during transit in a vehicle).
Follow setup steps as normal, if sensor zero fails re
attempt until the unit passes, this can take up to 30
minutes in some cases.
The NO sensor may require replacing. If another system is not readily available and patient
requires therapy, engage the manual override mode, replace
the system as soon as practically possible and alert the
Service Engineer.
Notications at Switch on
The below are a series of notications which may be seen at start-up (before the home screen) if an issue is detected with the NOxBOXi.
