Activate the Detector
Activate the detector in a safe area with an atmosphere of
20.9% oxygen and free of hazardous gas.
1. For first time use, charge the battery for up to 8 hours or
until LED light turns green using the charging adapter
provided. Refer to Charge the battery for more information.
2. Press and hold the button for three seconds.
3. For first time use, a Warming sensors message is
displayed and a 30 minutes countdown is displayed. In
most cases, this countdown only lasts a couple of minutes.
4. When the detector displays Pump test Block inlet,
block the pump inlet with a finger, and then after a couple
of seconds unblock the pump inlet.
The detector performs a quick pump test. A Pump Test
passed message is displayed.
If you do not block the pump inlet, the detector will turn off
after two minutes.
If necessary, you will be instructed by screen prompts to
calibrate newly-installed sensors.
The detector will then perform a self-test, including testing
the sensors. This process could take several minutes.
5. When the self-test is complete, press and hold the button
to zero sensors. After the autozero is complete, the detector
then checks the sensors for calibration and bump test.
If the detector identifies sensors requiring calibration or
bump testing, press the button and follow the on-screen
instructions.
