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.

Note

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.

Caution

Never use organic solvents such as thinner.

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.

Note

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