To wake the dosemeter, shake the unit as shown in the diagram above. When the 
sensor is activated, the dosemeter status indicator will flash (blue) twice and the 
dosemeter can be used. 
Note that the sensor may be activated when the dosemeter is removed from the 
charger unit or when it is handled. If the indicator light does not flash when the 
dosemeter is shaken, check that the dosemeter is not already awake by pointing the 
Reader Unit at the dosemeter and pressing the Stop button. 
If the indicator shows, the dosemeter is awake and ready to use. 
Please note that if the dosemeter is running, it will not go into Sleep mode. 
The dosemeter will only enter Sleep mode if it has been stopped for more 
than 1 hour and does not receive commands from the Reader unit. 
Please note that if the internal battery in the dosemeter is not charged, it will 
not be possible to wake the dosemeter from Sleep mode. Ensure that the 
dosemeter is fully charged before attempting to use the unit. 
Insert the dosemeter in the Acoustic Calibrator
Before the dosemeter can be reset or calibrated, it must be inserted into the Acoustic 
Calibrator cavity to allow communication between the dosemeter and the Reader unit.  
The figures here show the alignment of the dosemeter in the Reader cavity. Ensure that 
the Infrared window of the dosemeter is aligned with the Infrared Port of the Reader 
unit.

InfraRed 
Carefully twist the dosemeter
