Correction

Inspect the lens block focus reset sensor (Pin qs  of CN1551 of
VC-344 board) when focusing is performed when the control dial
is rotated in the focus manual mode and the focus motor drive circuit
(IC1553 of VC-344 board) when the focusing is not performed.

Inspect the lens block zoom reset sensor (Pin qg  of CN1551 of
VC-344 board) when zooming is performed when the zoom switch
is operated and the zoom motor drive circuit (IC1553 of VC-344
board) when zooming is not performed.

IC4501

VC-344 BOARD (SIDE A)

154 : A
155 : B

Due to the change of IC4501 (mechanism control), there are two
types of versions A and B
The EEPROM data are different according to respective versions.
Also, the IC4501 version can be checked by a discrimination method
by the model name or by the adjusting remote commander.

Changing the version does not make any changes in
schematic diagrams and the rest.

Make it sure to confirm the version after replacing IC4501.
