To help assure the highest degree of operating
safety for user and patient, SKYTRON has provided precautionary instructions throughout this
manual.
As with the operation of any surgical light, all
hospital personnel should be aware that a certain
amount of care must be exercised to maintain
patient safety and to keep your SKYTRON light
fixture performing at peak efficiency.
The following is a summary of the important precautionary instructions:
WARNING
Indicates a possibility of personal injury.
CAUTION
Indicates a possibility of damage to
equipment.
NOTE
Indicates important facts or helpful hints.
NOTE
To prolong bulb life, the sof-start bulb
protection circuit will cause a slight delay
before the bubs will illuminate.
NOTE
Always make sure that the handle is
properly engaged. Failure to perform
this procedure could result in the
inadvertent release of the center focus
handle.
NOTE
SKYTRON products are guaranteed
for proper performance with the use of
genuine SKYTRON CENTER FOCUS
HANDLES. After market competitive
handles and other disposable handles
will have varying results that could
ultimately affect the proper performance
and secure engagement of the center
focus handle. Such applications are at
the discretion of the user to ensure
patient safety.
CAUTION
To ensure product performance,
product longevity, and patient/staff
safety, always take caution to avoid
impact to the fixture when positioning.
NOTE
For LFSLFS position the second arm in
the same way on the opposite side of
the table.
NOTE
All repairs should be made using only
authorized SKYTRON replacement
parts.
WARNING
Be sure the power is turned "OFF" and
the bulbs have cooled before changing.
WARNING
DO NOT attempt to remove a bulb by
pulling on the glass surface or end cap.
This may cause the bulb to break off in
your hand.
NOTE
Halogen bulbs are sensitive to body
oils. DO NOT handle glass surface of
bulb as body oil from fingers can create
a "hot spot" and may cause the bulb to
burn out prematurely.
NOTE
To extend the life of the bulb reflector
surface, it should not be included in
normal cleaning. It should be cleaned
only if absolutely necessary. Clean
gently with a clean, damp, soft cloth and
a mild soap solution. NO abrasives.
NOTE
The system can support and balance a
monitor weight up to 22 lbs. Exceeding
the weight will result in poor balance and
performance.
NOTE
Refer to applicable light model
maintenance and parts manuals for light
fixture components.

Figure 1. Light Fixture Rotation Capabilities
The Stellar LFS series combines flatscreen monitor mounting with a surgical lighting system from a
single ceiling mount.
The LFS model allows a single flatscreen monitor
mount to be combined with up to 3 separate
lightheads. The LFSLFS model combines 2
flatscreen monitor mounts with up to 2 separate
lightheads.
The LFS radial arm assembly allows up to 90" of
reach for the flatscreen monitor with 345° of rotation
capability at the ceiling mount. Vertical travel of up
to 45.5" is provided.

The lighthead models available for use with the

ST29 and ST29TV. The ST19WC model is fixed
focus, the remaining models are all focusable.

The Stellar series surgical lighting system from
SKYTRON features fully adjustable positioning
and focus control for its cool, color-corrected,
multiple bulb, light source. Combinations of vertical
positioning and multiple rotational capabilities allow
the single, dual or triple lighthead models virtually
limitless positioning.
The fixtures are single point ceiling mounted with a
continuous 360 degree rotation capability at the
ceiling mount end of the radial support arm. See
figure 1. The balance mechanism which is attached to the radial arm by a vertical support tube,
provides the lighthead an additional continuous 360
degree rotation point. The balance mechanism is
an enclosed spring tension system. This allows
vertical movement of the lighthead while maintaining the lighthead position without drifting. The yoke
provides additional 360 degree rotation points for
lighthead pitch and roll.
The Stellar fixtures have a lighthead vertical travel
capability of 110°.
The adjustable focus mechanism which optimizes
the light output by superimposing all the light beams
into a single spot can be operated by non-sterile
personnel using the lighthead mounted focus knob.
All lightheads also have a removable, sterilizable,
focus/positioning handle. This allows all final positioning and focus adjustments or changes to be
precisely done by the surgeon. See figure 2.

2. Turn the light fixture main power switch "ON"
at the wall mounted control box and select the
desired intensity for each lighthead as required.
See figure 4. The mid-range position will provide
adequate illumination for most procedures. Full
intensity will usually only be required for extreme
deep cavity cases.
NOTE
To prolong bulb life, the sof-start bulb
protection circuit will cause a slight delay
before the bulbs will illuminate.

3. When the surgeon is ready to use the light,
install the sterilized center focus/positioning handle
using the following procedure. See figure 5. Be
sure handle is properly secured before using the
lighthead. Possible injury to patient or staff could
result if a handle is not installed properly.
a. Insert the handle into the lighthead at-
tachment ring.
NOTE
Always make sure that the handle is
properly engaged. Failure to perform
this procedure could result in the
inadvertent release of the center focus
handle.
b. Push the handle in, turn it right and left, and pull
the handle out to be certain that it is locked (PUSHTWIST-PULL). A distinct click can be heard when
the handle is properly engaged.
c. To remove the handle, push the release
button and pull the handle out.
4. Adjust the focus by moving either the nonsterile focus knob or the (sterilized) center focus
handle until all of the light beams converge on the
surgical site forming a single bright spot of light.
5. For low angle lighting approach, the lighthead
will move 90° below horizontal. Pull the lighthead
down by the positioning handles or the (sterile)
positioning/focus handle.
In the presence of flammable anesthetics, DO
NOT allow the lighthead to travel below 60 inches
from the floor.
6. When the light is no longer required, return
the lighthead to its full up position. Decrease the
intensity at the wall control, and turn the main power
switch "OFF".
NOTE
SKYTRON products are guaranteed
for proper performance with the use of
genuine SKYTRON CENTER FOCUS
HANDLES. After market competitive
handles and other disposable handles
will have varying results that could
ultimately affect the proper performance
and secure engagement of the center
focus handle. Such applications are at
the discretion of the user to ensure

LIGHTHEAD POSITIONING
General
To obtain the maximum benefit from your
SKYTRON surgical lighting system, the following
suggestions are offered as a guide for lighthead
positioning. Personnel who are trained in proper
lighting techniques can plan and set up the lighting
arrangements prior to the arrival of the patient.
Factors which should be considered when
prepositioning surgical lights are:
-Specific procedure to be done
-Patient position during procedure
-Position of surgical team
-Location of instrument trays or tables
-Location of IV stands
-X-ray equipment and personnel
-Anesthesia equipment and personnel
-Angulation and size of surgical cavity
CAUTION
To ensure product performance,
product longevity, and patient/staff
safety, always take caution to avoid
impact to the fixture when positioning.
The lightheads can be most effectively positioned
by using the following procedures:
1. Grasp the positioning handles on the lighthead
and pull the lighthead down to shoulder height.
Keep the lighthead at approximately a 45° angle to
easily position the support yoke. See figure 6.
Surgical Table Placement
For most procedures the surgical table should be
located with its center point directly under the light
fixture’s ceiling mount.
Pre-Positioning The Lighthead
Surgical light positioning requirements change not
only from procedure to procedure, they also change
from surgeon to surgeon. Final light positioning
and adjustment will be directed or done directly by
the surgeon. The objective of prepositioning is to
require a minimum of final adjustments after arrival
of the patient. The non-sterile focus control should
be located where it can be reached by non-sterile
personnel and the sterile positioning/focus handle
where they can be reached by the surgeon. Use
extreme care when prepositioning lightheads.
Bumping lightheads into one another, into walls, or
other equipment may alter bulb alignment which
affects proper focus adjustment.
