Cause and remedial action
● Has the unit been connected properly to the other connected
devices?
● If the system is configured in such a way that the picture is also
switched when the unit to be operated is selected, has the correct
unit been selected?
● Has the video signal setting been selected correctly?
● Has the stand-alone (Desktop) installation setting been selected
correctly?
● Switch to the camera picture.
● Exit the camera menu.
● Depending on the HDMI monitor you are using, you may
experience one or more of the symptoms described below, but
these are not malfunctions.
● The resolution of the characters in the camera menu displays
changes as the background image changes.
● Depending on the edge enhancement setting established for the
monitor, white lines appear in front of the black shadows of the
camera menus.
● Depending on the edge enhancement setting established for the
monitor, the background colors may be superimposed onto the white
parts of the camera menus.
● Is the focus set to manual?
Auto focusing is initiated as soon as the focus is set to auto.
● In some situations, it may be hard to focus at the auto setting.
In cases like this, select the manual setting, and focus manually.
● Was the focus adjusted at the Tele end?
First adjust the focus at the Tele end where the focusing accuracy is
higher, and then proceed with the zooming.
● Under some operating conditions, it may be hard to bring
subjects into focus.
In such cases, use the focus at the auto setting.
● Are you shooting in visible light?
The focusing position differs between visible light conditions and
infrared conditions due to the difference in the index of refraction.
It is assumed with the unit that the infrared light has a wavelength in
the vicinity of 850 nm when Night mode is used. Focus manually as
required.
