• The adjustment software supports the Multiple Tool II and the HS-I/F. You can,
however, double or triple the data transfer speed when the HS-I/F is used compared
with when memory is not expanded by using the expanded memory (CY9-7082-002).
We recommend using expanded memory to finish adjustments more quickly.
The Multiple Tool II transfers data at the same speed as when memory is expanded.
• Before you replace the main board with a new one, be sure to initialize the main flex
and make all the adjustments. The new main board is not written with initialize data.
• Be sure to terminate the adjustment by selecting F10 Quit. This clears the charging
inhibit.
• When communications is carried out with the camera, never press switch SW2. Doing
so will result in an error. Also, do not press the switches (e.g. AE, ranging) after
communications is started. Doing so might prevent adjustment, in particular AF
adjustment, from being carried out correctly.
• Do not attach or remove the lens during AF basic adjustments. Doing so might prevent
adjustment from being carried out correctly.
