Before daily use:
Make sure the sensor and audible port are clear of any obstruction such as debris
or blockages.
Perform the self-test to ensure the display, visual, audible and vibration alarms are
operating.
The sensor symbol stops blinking if the self-test is successful.
Ensure that the O
detector is zeroed at least every 30 days in a clear air
2
environment. See O
detector section for information on zeroing. The toxic gas
2
sensors (CO, H
S & SO
) may require calibration during the life of the product. ION

Science recommend bump testing frequently to ensure the sensor is functioning.
Perform a bump test at least every 30 days.
Please perform a bump test if the detector has been subject to physical impact,
liquid immersion, over limit alarm event, change of ownership or anytime the
detectors performance is in doubt.
Perform a bump test by exposing the detector to a concentration of gas that
exceeds the low alarm set points.
When selecting suitable bump test concentrations, please consider your local
health & safety exposure limits and ensure to take any necessary precautions when
handling these gases.
If the unit fails the bump test, attempt a calibration.
The accurate measurement of gas concentration depends upon the target gases
and the period.
The product is a gas detector, not a measuring device.
Do not attempt to replace the battery or sensor, the product is designed to be
maintenance free, changing these components will void the warranty.
If you suspect any malfunction or have any technical problems, please contact ION
Science.
