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.

1-6. Disconnecting/Connecting FlexibleCard Wire

The flexible card wire is used between the VF-67 boardand VR-226 board. Take care not to break this flexiblecard wire. This shorten the wire life.

Disconnecting

1. Turn off the power.2. Slide portions A in the direction of the arrows to

unlock and pull out the flexible card wire.

Connecting

n. Be careful not to insert the flexible card wire obliquely.. Check that the conductive surface of the flexible card

wire is not soiled with dust.

1. Slide portions A in the direction of the arrows andinsert the flexible card wire as far as it will go with theconductive surface down.

2. Slide portions A in the reverse direction to lock.

2-1. General Information for ElectricalAdjustment

2-1-1. Notes on Adjustment

1. When performing adjustment, read throughly thefollowing comments.

. The calibration of all measuring equipment should becompleted.

. Peripheral equipment (camera, and others) alignmentshould be completed.

. “2-1-4. Settings for adjustment” should be completed.

. Turn off the power before extending the plug-in boardusing the extension board.

wThere is a danger of an electric shock around the CRT dueto high voltage. Therefore, do not touch the CRT.Be very careful when service in a live.

2. Change the Picture Frame mode (4:3/16:9). When the unit is put into the 16:9 mode, set as follows.

1) Extend the AT-95 board of BVP-550/BVP-550Pwith EX-464 extension board.

2) Short between pins 76 and 100 on the EX-464board using a shorting clip.

. When the unit is put into the 4:3 mode, disconnect theshorting clip as above.
