Adjustment Adjustment 68
5.3.5 Strobo Adjustment
This process adjusts the amount of flash light with the lens positioned on the WIDE
(wide-angle) side and TELE (telescopic) side. Adjusted values are written in flash
memory on the Main Circuit Board. For this adjustment, use of a dark box or dark
room is desirable. Instead, however, you can use a room which is so prepared that no
external light enters directly.

Preparation for Adjustment
„
Stick six sheets of Strobo adjust charts (No.1091791) on a wall or board so
that there is no clearance between the six.
„
The wall or board to put those Strobo adjust charts on must be of a low
reflectivity. If the surface of the wall or board is bright, stick the charts on a
black sheet of paper wide enough.
„
To stick the six charts on the wall or board, use double adhesive tape between
the sheets and the wall or board so that no tape is seen from the camera side.
