Section 1: Listing of Safety Precautions

The following Safety Precautions must be observed when operating or servicing this surgical lighting system.
WARNING indicates the potential for personal injury and CAUTION indicates the potential for damage to
equipment. For emphasis, certain Safety Precautions are repeated throughout the manual. It is important to

review ALL Safety Precautions before operating or servicing the unit.

Strictly following these Safety Precautions enhances your ability to safely and effectively utilize the unit and
helps the customer avoid improper maintenance methods which may damage the unit or render it unsafe. It
is important to understand that these Safety Precautions are not exhaustive; customers are encouraged to
develop their own safety policies and procedures to enhance and compliment these Safety Precautions.

WARNING – ELECTRIC SHOCK AND BURN HAZARD:

Disconnect all utilities to lighting fixture before servicing. Do not install the lighting fixture unless all utilities
have been properly locked out. Always follow OSHA Lockout-Tagout and electrical safety-related work
practice standards. (See 29 CFR 1910.147 and .331 through .335.)

Do not remove covers or perform service other than as described in this equipment manual. Refer servicing
to qualified service personnel. (Maintenance Manual P764330-226.)

WARNING – EXPLOSION HAZARD:

Do not use lighting fixture in the presence of flammable anesthetics.

WARNING – PINCH AND CRUSH HAZARD:

Do not pinch fingers between the structural plate and the vertical tube as the assembly is lifted.
The safety ring must be installed.
Pinch points are created during extreme articulation of the suspension system. Do not place hands on or near

the suspension knuckle during lighthead articulations.

WARNING –IMPACT HAZARD:

Do not remove tension screw from the spring arm joint until the lighthead has been securely installed onto
the spring arm. Note: This warning applies at both installation and de-installation procedures.

WARNING – PERSONAL INJURY HAZARD:

Do not attempt to replace the lamp unless power is turned off and the lighthead has cooled sufficiently.
Do not attempt to clean lighthead unless power is turned off and the lighthead has cooled sufficiently.
Do not remove monitor-arm safety pin until monitor is installed.
Monitor extension arm must have monitor (or equivalent counterweight) installed to keep arm in required

positions while installing sliding guards.
Avoid looking directly at high-intensity light, whether at the lamp or directly at the lighthead. Eye injury may

result.

1-1

764330-226

WARNING – POSSIBLE PATIENT INJURY HAZARD:

Failure to engage the lighthandle cover completely may result in cover falling from lighthead during the
procedure.

WARNING – BIOHAZARD:

Sterile disposables are intended for single use only.
Universal precautions must be observed when disposing of any single use disposable item.

WARNING – DISPOSAL HAZARD:

This product contains materials which may require disposal through appropriately licensed and permitted
hazardous waste management firms.

CAUTION – POSSIBLE EQUIPMENT DAMAGE:

Use of any disinfectant solution OTHER than those listed below may cause discoloration or deformation on
the polycarbonate lens surface: Coverage® Spray HBV, Coverage® HBV Concentrate, T.B.Q.®, or Coverage
Plus®, CoverageTM Spray Disinfectant Cleaner, or Germicidal Cloth. Cleaning solutions other than those listed
have NOT been tested for compatibility or effectiveness. Always follow manufacturer instructions for
concentrations and use of cleaning products.

Use only recommended cleaning/disinfecting and/or anti-static agents on this light. Some degree of staining,
pitting, and/or discoloration could occur if a phenolic-, iodophor-, or glutaraldehyde-based disinfectant is

used on the surfaces of this light. Also, use of alcohol or aerosol spray cleaner/disinfectants (e.g., Lysol®)
containing a substantial amount of alcohol in the formula can damage the polycarbonate lens.

Prevent leakage of fluids into interior of lighthead.
Avoid discoloration of control center keypad and display. Do not clean control center with Betadine® solutions

or allow such solutions to contact keypad and display surfaces.
Do not scratch optical coating on accessible portions of optic assembly when cleaning; always wear rubber

gloves and use only a clean, white, lint-free cloth when wiping internal surfaces.
Appropriate components of this lighting system have been tested and found in compliance with IEC 60601-

1-2 (1st Edition 1993-04), Medical Electrical Equipment – Part 1: General Requirements for Safety;
Electromagnetic Compatibility (EMC). There is, however, a potential for electromagnetic or other interference
between this equipment and other devices. Should you experience interference, relocate this device or
minimize the use of the affected equipment while this device is in operation.

Do not touch the glass portion of the lamp with bare fingers. Skin oils can cause deterioration of material
leading to possible failure of the lamp.

Accurate measurement and calculation in finding the point where the first hole is drilled for the safety ring is
of critical importance in correctly installing the vertical tube. Check all measurements and calculations twice
before drilling the first hole.

Do not pinch wires that exit the vertical tube as the assembly is lifted. Gently route wires from the vertical tube
out of the way as the suspension system is lifted into place.

1-2

764330-226

CAUTION – POSSIBLE EQUIPMENT DAMAGE (Continued):

Do not pinch wire on the ceiling structure or vertical tube.
During all mounting steps, ensure wires are not pinched between mechanical components of suspension,

spring arms, or lightheads.
Harness connectors must be slipped into expandable sheathe before routing through monitor yoke.

• Failure to use sheath may cause connector damage during routing.

• Slip sheathe only far enough onto the harness to protect connector bundle. If sheathe is slipped too far onto
the harness, removing it after routing may be difficult.

Do not touch glass portion of lamp with bare fingers. Skin oils can cause deterioration of material leading to
possible failure of the lamp.

Sliding guards may be damaged if not installed properly into internal grooves.
On early light systems, the wire clamp must be loosened to allow the wiring within the vertical tube to be free.

Section 3: Operating Instructions

3.1 GENERAL INSTRUCTIONS

The wall-mounted Harmony™ LA Control Center
allows the user to adjust the lighthead intensity level
(brightness) by pressing a membrane switch (or “but­ton”). An identifying number on the control display
corresponds to the same number on the lighthead
suspension arm. Additionally, each lighthead has its
own “onboard” intensity controls, located on the
above the lighthandle adjacent to the lens. These
controls are usually referred to as the surgeon’s
control buttons or as the surgeon’s control. (See
Figure 3-2.)

3.1.1 To Adjust Lighthead Intensity Levels:

WARNING-EXPLOSION HAZARD: Do not use
in the presence of flammable anesthetics.

1. Press ON touch pad.

2. Intensity levels for one or two lightheads can be
controlled from one control center. A lighthead’s
surgeon’s control buttons adjust the intensity level
for that lighthead.

Important: Avoid control center faults. Do not con­tinuously press and hold any control center buttons
for more than 15 seconds.

3.1.2 Control Center

WARNING-EXPLOSION HAZARD: Do not use
in the presence of flammable anesthetics.

See Figure 3-1.

1. Use the “Select Light” touch pads to move the
display indicator up or down until it aligns with
the appropriate lighthead.

2. Once the lighthead is selected, press either the
button to increase light intensity level, or the but­ton to decrease light intensity level.

3. If “All Lights” is selected, intensity for all light­heads in the system is increased or decreased
simultaneously.

NOTE: For longer lamp life, use lowest intensity level
suitable for surgical procedure.

with “+” symbols to increase the lighthead inten­sity. Press any of the surgeon’s control buttons
molded with “-” symbols to decrease lighthead
intensity.

NOTE: For longer lamp life, use lowest intensity level
suitable for surgical procedure.

3. To turn lighthead OFF.

a. At the control center: press the “Select Light”

button until indicator points to the appropriate
lighthead on the display. Press the “Decrease
Intensity” button until the light goes out.

b. At the lighthead, press and hold any of the “-”

membrane buttons untilthe light goes out.

NOTE: Press the decrease intensity button (-) on
the lighthead surgeon’scontrol for an additional 5
seconds, to turn off all lightheads in the system.

nity.
A Lamp Status LED is located on the lighthead (see

Figure 3-3). If this LED is flashing, it indicates that
the lighthead is using the backup lamp and the
primary lamp should be replaced.

Check the lamp status LED each time the surgical
light is used.

A secondary lamp inside Harmony LA 500 light­heads automatically turns on when the primary
lamp fails.

If the lamp status LED is blinking, replace the failed
lamp(s). (See Lamp Replacement, Section 6.) After
the lamp is replaced and power restored to the
lighthead, the primary lamp lights, the LED stops
blinking and the graphic display changes to “lamp
ready.”

Lighthead Positioning

LIGHTHEAD POSITIONING

CAUTION: Do not bump lightheads into walls
or other equipment.

Lightheads can be positioned by using either the
sterile handle, or by grasping the non-sterile handle
around the lighthead housing. The following two
paragraphs describe the positioning characteristics
of the lighthead from outside or within the sterile
field. To optimize shadow control, position the light­head as appropriate before starting the intended
surgical procedure.

Lighthead may (1) rotate continuously around ver­tical suspension tube; (2)rotate continuously around
central hub; (3) rotate continuously about suspen-

sion arm; (4) tilt forward or backward in yoke ap­proximately 310°; and (5) move up or down by
pivoting at suspension elbow 15° up, and 85° down
until vertical tube and suspension arm describe a
straight line.

Monitor arms are capable of the following articula­tions: (1) rotate 300° at the central or secondary
spindle; (2) rotate 330° at the horizontal extension
arm; (3) rotate 320° a the yoke transition; (4) move
up or down by pivoting at spring arm knuckle 20°
up, and 40° down. Flat panel yoke also allows (5) tilt
forward 15° or backward 75° in yoke. Additionally,
the flat panel yoke can be rotated for either portrait
or landscape display. See Figure 3-4.

3.5 LIGHTHANDLE AND LIGHTHANDLE COVER

3.5.1 Installing and Using Lighthandle and

Lighthandle Cover

WARNING – POSSIBLE PATIENT INJURY
HAZARD: Failure to engage the lighthandle
cover completely may result in cover falling
from lighthead during the procedure.

Lighthandles are used to position Harmony LA 500
lightheads, allow access to intensity control on each
lighthead, and to adjust lighthead pattern size. To

3-4

764330-226

avoid accidental contact with the non-sterile
surgeon’s control buttons, the lighthandle should
always be used with a disposable, sterile lighthandle
cover (available separately from STERIS®).

• If the lighthandle adapter is not already in place,
align the tab on the adapter with the channel in
the mounting ring and thread the adapter in until
fully engaged. (See Figures 3-6a and 3-6b.)

• Prior to starting a procedure, ensure that the
lighthandle is in place. Install the lighthandle by
threading onto the adapter and firmly tightening.
(See Figure 3-6c.)

Surgeon's Control Buttons

• Remove the sterile lighthandle cover from its
packaging and install onto the lighthandle. (See
Figure 3-6d.)

• To ensure the lighthandle cover remains in place
during the procedure, the groove in the cover
must be fully engaged with the groove in the
lighthandle.

• The lighthandle can be removed for cleaning or
sterilization by unscrewing it from the handle
adapter. The lighthandle can be sterilized using
standard hospital cycles. Do not use the light­head during a sterile procedure unless a dispos­able cover is installed on the lighthandle.

3.5.2 METAL STERILIZABLE HANDLE

WARNING-STERILITY ASSURANCE HAZ­ARD: Do not use the surgeon’s control but­tons unless a disposable sterile cover is
installed. If the sterilizable lighthandle
(metal) is used without a disposable cover,
the surgeon’s control buttons are not pro­tected by a sterile covering.

The metal sterilizable handle is used to position the
Harmony LA lighthead and to adjust the light pat­tern size. The sterilizable handle may be used in
place of a disposable sterile lighthandle cover.

The plastic lighthandle should be removed prior to
installing the metal sterilizable handle. To do so,

simply unscrew it from the threaded handle adapter.
Prior to starting a procedure, install a clean, steril-

ized metal handle by screwing it onto the threaded
handle adapter. Ensure handle is firmly tightened
prior to use. The gap between the flange on the metal
steriliizable handle and the surgeon’s control but­tons prevent accidental contact with the non-sterile
surface of the buttons.

The metal sterilizable handle can be removed for
sterilization by unscrewing it from the adapter.

The metal sterilizable handle can be sterilized using
standard hospital cycles steam cycles intended for
lumens. Always sterilize handle between surgical
procedures.

3.10 VIDEO CAMERA OPERATION

The optional video camera is integrated into a re­movable handle that can be fitted to any Harmony
LA 500 or 700 lighthead. Whenever the video option
is used, a separated sterile disposable cover must be
fitted over the camera before each procedure. This
cover allows the camera to be grasped and used in
the same way as a standard handle, including posi­tioning the lighthead for optimal illumination, ad­justing lighthead intensity and pattern size, as well
as positioning the video image field for the best view
of the procedure. The sterile cover must be removed
from the camera and discarded after each proce­dure.

Video and control signals are turned on or off at the
control center; any of the optional remote control
units (see below) provide similar control functions.
The control center also provides additional control
for video brightness and contrast, color gain, still­image capture and time and date display.

Three optional remote devices can control camera
functions: a hand-held wireless control, Hermes
voice-activated control (verbal commands and hand­held pendant), or a foot control.

The control center functions by transmitting signals
via a control cable to the camera located in the
lighthead.

The optional wireless control functions by transmit­ting infrared signals to the control center. To initiate
camera functions with either control, press the ap­propriate touch pad on the control face panel. The
hand-held control’s IR (infrared) transmitter must
be within approximately 15 feet maximum and 50° of
the control center receiver. The control touch pads
are used to control the following camera functions:

Zoom–for determining the level of detail visible in
the image field. The Zoom function adjusts the im­age field continuously between two extremes:

+ (Telephoto). At extreme telephoto, the camera

captures an image showing great detail in a
small area.

NOTE: At extreme telephoto, any motion of the light­head/camera will be exaggerated (jerky). The field of
focus has little depth at this extreme, forcing the Auto
Focus function (if enabled) to refocus the camera when
any object (such as a hand) enters the image field, or if
camera position is adjusted. The camera is also sensi­tive to light level changes at extreme telephoto.

– (Wide Angle). At extreme wide angle, the cam-

era captures a large, image with less detail than
telephoto.

NOTE: At extreme wide angle, the image field pos­sesses a greater depth of focus and less sensitivity to
light level changes.

Rotate–Use this function to change orientation of
the video field. Image field can be rotated in either

clockwise or counterclockwise directions.
Bright–Use this function to affect the overall bright-

ness (or darkness ) of the video image. The Bright
control can be set to adjust itself automatically.

Manual Focus–Use this function to manually set the
focus for close-up shots or other special applica­tions. The Auto Focus function must be toggled off
to enable manual focusing. Adjust the clarity of
focus by pressing the + or – touch pads.

NOTE:
subject;

+

touch pad moves the lens slightly closer to

–

touch pad moves the lens slightly away from

subject.

Auto Focus – Use this function to toggle Auto Focus
on or off. When Auto Focus is ON, the camera
automatically focuses on the object in the image
field closest to the camera lens. When Auto Focus is
turned OFF, the camera maintains focus on the last
object upon which it was focused, until Auto Focus
is turned back on.

NOTE: It may be necessary to toggle Auto Focus OFF
when using the camera at extreme telephoto (close up),
to prevent the camera from refocusing on hands and
other objects introduced into the image field while
videoing procedures.

Red Gain/Blue Gain – These controls are used to
adjust image color settings, and are intended to
allow the user to compensate for changes in color
temperature provided by differing light sources.
The gain control can be set to adjust automatically.

3.10.1HERMES-Ready Control Center

The Hermes Control Center functions by transmit­ting signals through an interface cable connected to
the wall control. When used, the interface cable
should be routed to avoid surgical personnel foot
traffic. The control center is intended to allow per­sonnel within the sterile field to operate all camera
functions using verbal commands or a hand-held
pendant. Refer to the Hermes operating manual for
more information.

3.10.2Optional Foot Control

The foot control functions by transmitting signals
through a cable connected to the control center.
When the foot control is used, the cable should be
routed to avoid surgical personnel foot traffic. The
foot control is intended to allow personnel within

3-10

764330-226

the sterile field to operate the zoom and rotation

TM

Surgical Lighting and Video System

ZOOM RO TATE

functions of the camera.

NOTE: Zooming completely out causes image distor­tion within the illuminated area.

Foot control is used to control zoom and rotation
functions. Press on appropriate sides of foot pedals
to activate foot control functions. Functions con­trolled through the foot control unit are identical to
those controlled through the optional hand-held
wireless control or control center.

3.11 GUIDELINES FOR MAXIMIZING

VIDEO IMAGE

The following steps will aid in maximizing video
imaging effectiveness.

1. Energize the light at medium setting on the con­trol center, and position the lighthead approxi­mately 39" (1000 mm) from the surgical site.

2. Using the hand-held remote, or the control center,
zoom in or out (+ or -) until the desired image fills
the viewing screen of the monitor.

3. If the light pattern (white circle) does not fill the
monitor’s screen (shaded square), the image in­side the pattern will be distorted.

4. Reposition the camera to orient the focal point
(center of the desired image) at the center of the
viewing screen.

Adjust zoom and rotation as needed:

5. The camera may be zoomed to the full 10x zoom
and rotation orientation adjusted as needed.

6. Clockwise and/or counterclockwise orientation
is adjusted by using the curved arrow(s) on the
hand-held control, the control center or the op­tional foot control.

3.11.1Engage Manual Focus

As instruments are introduced to and removed from
the surgical field, the auto focus will attempt to
focus on the nearest object, possibly causing the
image to blur intermittently. To prevent this effect,
once the camera has been positioned and focused
onto the surgical site, the manual focus mode may be
engaged to maintain image clarity during the proce­dure.

For deep cavity illumination, it may be necessary to
engage the manual focus to focus beyond the nearest
object (i.e., the surface area surrounding the inci­sion) so that the desired image can be viewed clearly.
