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.

Diagnostics
High The NOxBOXi performs 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 High 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.
