1-4. Cleaning
1-4-1. Cleaning of Viewfinder
By extracting VF tube sub assembly, lens and MC protec-tor can be easily cleaned. And also dust on the CRTsurface or mirror can be easily cleaned off.
1. Turn the hold ring to the left and extract the VF tubesub assembly.
2. Detach the eyecup.3. Remove the MC protector with the filter holder.4. Clean the lens and MC protector with a commercially
available camera lens cleaner. Blow off dust with ablower carefully so as not to flaw the mirror.
5. After the cleaning is completed, install by reversingthe preceding steps. Align red lines of the VF tube andVF tube sub assembly when inserting, and turn thehold ring to the right until it locks.
n. Do not use any type of solvent, such as alcohol, benzine
or thinner to remove stains.. Be sure to attach the eyecup to the VF, or the MC
protector may come off.. To protect the viewfinder lens from drops, put the MC
protector in the filter holder and attach the eyecupsecurely.
1-4-2. Care After Using at SpecialEnvironment
It is recommended to check the following items aftergathering the news at seaside, dust area or spa.
1. Clean off sand and other dust in the unit carefully.2. Do not allow salt in seawater or sulfur in spa to contact
a not-painted surface of the cabinet. They may cause tocorrode. Clean with alcohol immediately if contacted.
3. Clean the connection surface of connectors.4. Carry out the common operation check.
