8-2 Maintenance
8-2-1 Cleaning the Video Heads
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.
8-2-2 Cleaning the Viewfinder
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.
Disassembling the eyepiece for cleaning
1
Detach the eyepiece from the viewfinder barrel.
For the detaching procedure, see “7-2-4 Detaching the
Eyepiece” on page 110.
2
Remove the eyecup from the eyecup holder.
3
Remove the protecting filter, together with the packing
ring, from inside the eyecup holder.
4
Detach the protecting filter from the packing ring.
Fog-proof filter
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).
Fitting the fog-proof filter
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.
