Select  a  cover  adapter  with  an  insert  (bought  separately)  of  the 
required diameter depending on the outer diameter of the objective 
lens of the day device.
The  figures  42  mm,  50  mm,  56  mm  in  adapter's  model  name 
correspond to the optical diameter of the lens of your day device.
Measure the outer diameter of the housing of the lens of your day 
device and select an insert based on the data in the table below. 
Example. If the lens diameter of your day device is 42mm, and the 
measured outer diameter of the housing of the lens of your day device 
is 47.2 mm, you need to use an insert with marking “Ø 47”.
