DJUSTMENT
Three types of inhibit voltages must be adjusted: 2CR5 lithium batteries, PDB (size-AA
batteries), and PDB (Ni-MH). However, by selecting Overall Correction, all the inhibit volt-
age levels will be based on the 2CR5 battery’s level. Normally, after replacing the main
flexible board, do the Overall Correction. If the user complains that only one type of bat-
tery (like the PDB Ni-MH) becomes exhausted quickly (assuming that there is no leaking
current or other problem), the adjustment can be made only for that battery type.
Tip: If the user complains that the batteries become exhausted fast, first check for any
problems with leaking current and other operating current. Compensate by setting
the inhibit voltage level slightly lower with the Overall Adjustment or Individual
Adjustment. Note that if it is set it too low, it will not be applied because the
adjustment software has certain limits. (If it is set too low, the lens EMD operation
will become unstable.)
PURPOSE
This adjustment sets the minimum power voltage required to ensure operating
precision of the camera’s operating parts. Any lower voltage prohibits the respec-
tive camera operation. It also adjusts the battery check icon indications dis-
played on the external LCD panel.

Part 4: Electrical Adjustments
• This adjustment is required after the main flexible board is replaced.
• Since the system connector has battery check resistors (RBAT, RBAT2),
adjustment and check are also required after the system connector is
replaced.
