Magnetic Safety Switch 

The PhotoSharp is equipped with a magnetic safety 
switch that is located on the right hand side of the 
exposure unit cabinet and lid. If the magnetic safety 
switch is open (lid up) the light will not operate.  

When the lid is closed the magnetic safety switch 
will complete the circuit connection and the light will 
operate.  

Shutter 

If the lid is opened during the exposure cycle, the 
shutter on the light source will automatically close to 
protect the user from harmful UV rays.  

Photo Cell 

A yellow photo cell is located at the rear of the          
PhotoSharp and monitors the light source. The photo 
cell sense the light emitted from the light source when 
the shutter opens during the exposure cycle. If the   
photo cell does not sense the lamp has illuminated, it 
will countdown one second on the main timer and turn 
the timer off.
