MODEL 22 dosemeter
The layout of the MODEL 22 
dosemeter is shown on the right.  
The microphone capsule is 
mounted in the top of the 
dosemeter in a shock mount to 
reduce the noise generated from 
movement or handling of the 
case. 
The dosemeter is controlled via 
an Infrared link to the Reader 
unit. Behind the Infrared window 
are the transmitter and receiver 
for communication with the 
Reader. 
The charging point for the 
dosemeter is on the bottom in 
the centre and this is also used 
for the mounting of the 
dosemeter. 
RK1 Keyfob Remote Control
The RK1 Keyfob Remote control is designed to 
start and stop the dosemeter. 
The Start and Stop buttons are used to send 
commands to the dosemeter. When the Start 
or Stop buttons are pressed, the Status 
indicator will light to show that the button has 
been pressed. 
The Infrared signal is sent from the 
transmitter on the front of the Keyfob. Ensure 
that this transmitter is kept clean. 
If a button is pressed and the Status Indicator 
does not show, the battery may need to be 
replaced.
