OTWB (One-Touch White Balance)
Adjust the white balance before recording to record image in optimum
color tones.
1. Display an exclusively white live image.
· During transmitted light observation, remove the specimen.
· During reflected light observation, set a piece of white paper in place of
the specimen.
2. Press the OTWB button @ to adjust the white balance.
3. When the white balance is set, message "White balance setting is com-
pleted." is displayed on the monitor and disappears automatically in 3
seconds. This message can also be switched off by pressing any button
other than the main switch.
}If the adjustment fails, message "white balance setting failed." is displayed.
As this message does not disappear automatically, press the SET/OK
button to switch it off and retry the adjustment.
}The white balance adjustment fails when the live image is not com-
pletely white, the exposure is inappropriate (too bright or too dark), etc.
}The white balance can also be adjusted using AUTO WB and manual (by
means of direct entry of color temperature) as well as OTWB (One-Touch
White Balance), and the adjustment mode can be selected in the MENU
display. For details, see Setting the white balance (WB) mode (p. 35).
