To clean the video heads, use a Sony BCT-HD12CL 
Cleaning Cassette. Follow the instructions given with the 
cleaning cassette, as incorrect or excessive use could 
damage the video heads.
To clean the heads, perform the following:

Load the cleaning cassette according to the procedure 
described in “Loading a cassette” (page 32).

The tape runs automatically in PLAY mode for about 5 
seconds to clean the head.
After the tape runs, the cleaning cassette is automatically 
ejected.

Do not run the cleaning cassette 5 or more times 
consecutively.

Use a dust blower to clean the CRT screen and mirror 
inside the viewfinder barrel.
Clean the lens and protecting filter with a commercially 
available lens cleaner.

Never use organic solvents such as thinner.

Detach the eyepiece from the viewfinder barrel.

Remove the eyecup from the eyecup holder.

Remove the protecting filter, together with the packing 
ring, from inside the eyecup holder.

Detach the protecting filter from the packing ring.

Depending on the temperature and humidity, the protecting 
filter may mist because of vapor or your breath. To ensure 
that the viewfinder is always clear, replace the protecting 
filter with a fog-proof filter (Part No. 1-547-341-11, not 
supplied).

Replace the protecting filter on the packing ring with the 
fog-proof filter.
Be sure to correctly assemble the fog-proof filter, the 
packing ring, and the eyecup so that the reassembled 
eyepiece is waterproof.

When cleaning the fog-proof filter, wipe it very gently with 
a soft cloth to avoid damaging the anti-fogging coating.
