MAINTENANCE FOR AREARAE STEEL
7-7
6. Identify the location of a specific toxic sensor and
remove the sensor by gently pulling the sensor
upward. Note: In the AreaRAE Gamma and AreaRAE
Gamma Steel, the gamma radiation sensor replaces
the Toxic 2 sensor.
7. Plug a new sensor into the empty sensor socket. Make
sure that black line on the sensor label is lined up with
the white marker on the PCB and the sensor pins are
aligned with the socket before pushing down the
sensor.
8. Replace the gas piping plate and tighten the three
screws to hold down the sensors.
9. Reassemble the AreaRAE Steel.
10. Connect the battery pack to the printed circuit board,
place the battery in its compartment, and replace the
cover plate and its four screws.
11. Turn the AreaRAE Steel on, and the monitor
automatically recognizes the sensors installed and
configures the monitor accordingly.
NOTE:
The gamma radiation sensor installed in the
AreaRAE Gamma Steel does not usually need to be
replaced unless it is damaged or malfunctioning. To
replace the gamma sensor, remove the dummy sensor
plug from the PCB and the gamma sensor module.
Replace it with a new module and reconnect the dummy
sensor plug on the PCB.
