White Balance
Every DSM is shipped with pre-configured white balance settings.
Note
These settings may not be optimal for the specific lighting conditions.
►
To reset the white balance to the factory settings, press “Reset to Fac-
tory WB” button.
For the best image, the DSM should be white-balanced.
►
Set the DSM light to the surgeon’s normal working conditions.
►
Place the white balance card PV030 under the light. Ensure that the
entirety of the live view is filled by the card. Never use gauze, tape,
sheets, or other fabrics which may have been bleached.
►
Tilt the card and move it either closer or farther from the light as the
software instructs.
►
Select White Balance
button to perform white balance and follow
the on-screen instructions to complete the white balance process.
►
Test the colors by viewing your hand under the DSM. Repeat the pro-
cess if the colors look incorrect.

Recording
In the Recording
panel the following settings can be modified:
■
Movie or snapshot file formats
■
Auto-record
■
Fullscreen recording
■
Frame rate
■
Movie quality
■
DICOM 3D recording
Note
Recording settings cannot be changed while recording a case.
Basic settings
Note
Fullscreen recording is not recommended due to possible delays in the
image.
►
Select the desired recording settings:
– Movie format: Press the radial button of either “AVI” or “MOV”
(default: MOV).
– Auto-Record: check the checkbox to have the software start record-
ing as soon as “Start Case” is selected (default: unchecked).
– Fullscreen: Check the checkbox to record the surgery screen with all
annotations and overlays. If unchecked, the software will only
record the raw DSM input (default: unchecked).
– Snapshot format: Press the radial button of either “JPEG” or “PNG”
(default: JPEG).
Advanced settings
Note
Increases or decreases to frame rate and quality can be expected to have
relative increases or decreases to file size.
►
Select the desired advanced recording settings:
– Frame rate: frames per second that will be captured during a
recording. Select the desired frame rate by pressing or pressing and
dragging the slider from any value between 30 fps and 58 fps
(default: 45 fps).
– Quality: can be adjusted from 0 to 10, resulting in respective
changes to recording quality. Notably, minimizing the slider can
introduce compression elements such as haloing or blurry frames to
the recording with the benefit of reducing file size. Select the
desired quality setting by pressing or pressing and dragging the
slider from any value between 1 and 10 to change the quality for
recordings (default: 5).
– Squeezed SxS (side by side): checking the checkbox reduces resolu-
tion of saved media to 1920 × 1080 (default: unchecked). Select
this option when smaller file sizes and/or the ability to edit with 3rd
party editing software are required.
– DICOM Record 3D: when a DICOM patient is selected at the start of
a case, all media recordings will be in 2D by default. Check the
checkbox to record all DICOM case media in 3D. Uncheck the check-
box to record in 2D again.
Note
Non-DICOM patient case media are in 3D by default, therefore the “DICOM
Record 3D” feature is disabled when a non-DICOM patient is selected.

Display
In the Display
panel certain display settings can be modified, including
the view type, 3D format, and polarity of connected monitors (see
Chapter 3.3.3 for a list of compatible displays).
Identification information (numeric identifier, model number, 3D format,
polarity, resolution, and view type) will automatically appear on the live
image of each connected monitor while the Display settings panel is open.
Note
For displays intended for use (see Chapter 3.3.3), the 3D format and polarity
(“Swap 3D”) are automatically detected and set to their ideal pre-configu-
rations, as long as “Detect” remains enabled with the default panel settings.
►
To return to the ideal pre-configuration after making changes, select
“return to defaults” button, then ensure “Detect” is enabled.
Detect
►
Press the “Detect” button to turn this feature on or off.
Detect is set to “Off” by default to allow the software to automatically
configure the connected displays to their saved settings.
Display List
►
To view or manually modify settings for a specific display, select the
corresponding numeric identifier for that display from the “Display”
drop-down list.
View
►
Press the “View” drop-down list to assign a view type to the selected
display.
The available view types are:
■
Control
■
Surgery
■
Assistant 180
■
Assistant 90 CW
■
Assistant 90 CCW
“Surgery” view is a non-interactive secondary view with the primary func-
tion of displaying the live image. “Surgery” view will display relevant noti-
fications as they appear on the “Control” view.
“Assistant 180", “Assistant 90 CW” (clockwise), and “Assistant 90 CCW”
(counter-clockwise), are “Surgery” views that are rotated as indicated.
Note
At least one display must be assigned a “Control” view type. The touch-
screen display is assigned as the “Control” view by default.
3D Format

When “Detect” is set to “Off”, press the “3D Format” drop-down list to
change the 3D format for the selected display from the following avail-
able options:
