Note About The Battery Terminal - Sony PDW-680 Operation Manual

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 (option, part No. 1-547-341-11).
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.
