insure continued compliance with all safety standards.
System Description
The RetCam II system consists of several modules mounted in a stable, high quality integrated
mobile cart for easy, safe transportation from one location to another. The front pair of lockable
casters allow for easy maneuverability and positioning, while the fixed rear wheels guide the
unit in a straight line during transport. (Ref. Figures 1 and 2)
1) Display: A high resolution LCD flat panel display is standard with the system.
2) Control Panel: A membrane control panel turns the system on with one button, and has
controls for illumination intensity, camera focus and snap (capture an image or start/stop
video recording).
3) Handpiece: The handpiece contains the actual 3-chip CCD. It is light weight and easy to
use. The front lens pieces are removable, and allow quick and easy exchange.
4) Interconnect Cable: The interconnect harness contains three separate cables, the fiber optic
for transmission of illumination light, the camera cable, and the focus motor control cable.
5) Light Box: The light box contains a CCD camera control unit, a halogen illumination light,
and the control circuitry for light intensity, focus, image capture and system logic.
6) Computer: The computer is controlled by a keyboard and trackball. It is a Pentium4 based
system, running a specialized Embedded Windows XP, with two internal DVD storage
drives and media and proprietary software. The system has an integrated network adapter,
and USB hub.
7) Uninterruptible Power Supply (UPS): The computer, display and optional image printer are
powered by an Uninterruptible Power Supply. The UPS helps to protect against accidental
loss of images due to power surges or sudden power loss.
PN 04-03-023 Rev A, Service Manual, RCII

Cleaning Procedures
For cleaning purposes, the RetCam II is divided into two categories:
1. The Lens Piece that contacts the patient
2. The rest of the system
3.2.1
The Lens Piece
The Lens Piece should be cleaned thoroughly between patients to prevent the spread of
infectious disease. As recommended by the American Academy of Ophthalmology, the
cleaning liquid of choice is 70% isopropyl alcohol. Moisten a clean towelette with the solution
and use a gentle wiping action across the front of the lens piece, being sure to pay special
attention to the concave contact lens area. To prevent irritation to the next patient from residue
left on the lens, rinse the tip of the lens piece thoroughly with disinfected distilled water.
Warning: To avoid damage, do not autoclave any part of the RetCam II
system.
The American Academy of Ophthalmology also recommends disinfecting with 1:10 dilution of
bleach for 5 minutes.(refer to page inserts following this page). .
PN 04-03-023 Rev A, Service Manual, RCII
20
4mm (0.16”)
Immersion to only 4 mm
Fig 5 Lens Tip cleaning
WARNING: To handle chemicals safely, consult Material Safety Data
Sheets (MSDS) before using isopropyl alcohol or bleach.
Note: If you disinfect with bleach, you must rinse the frontmost part of the lens piece
with disinfected distilled water, and make sure the lens piece is wiped completely clean
before using on a patient.
Note: Never immerse the entire lens piece or handpiece in any liquid or solution. For
disinfection purposes, you can Immerse no more than 4mm (about 1/16”) of the tip of
the lens piece. In an inverted position. FOR NO MORE THAN 15 MINUTES.
Immersing more or longer than this causes corrosion of the lens piece and voids the lens
warranty. Use water, bleach, 3% hydrogen peroxide or isopropyl alcohol. Permissible
immersion depth is illustrated in the Figure above. It is important not to immerse the
join where the polished metal tip meets the painted housing, since it is susceptible to
corrosion.
3.2.2 System Cleaning.
As with any medical device, use good public health practices when handling the
equipment, based on CDC guidelines. In addition, as with typical office equipment, a
gentle wiping with a cloth moistened with mild soap and/or water is recommended. Do
not spray cleaning solutions directly on the computer or other module, spray the cloth
instead. The cart and side panels can be sprayed with a mild soap and/or water solution
if care is taken not to introduce the mist into the modules.
PN 04-03-023 Rev A, Service Manual, RCII
21
The lens piece should be checked before each use for damage to the front contact lens
and surrounding surface. The interconnect cable and connectors should be checked for
damage to the end connectors and protective covers.
WARNING: Always inspect the lens before use for damage such as
chips, cracks or roughness that could injure the patient’s eye.

3.3 Fluorescein Angiography Frequently Asked Questions
Q: Can the FA Light Source generate other colors and wavelengths of light?
A: No, it is designed for 471 nanometer blue excitation exclusively.
Q: How long does the Xenon bulb last?
A: The bulb is a special order and extensive testing data does not exist. However, a guideline is
that the intensity may reduce to one half the original value after 50 hours of use, and then
continue to reduce slowly after that. Some users have been performing successful FA imaging
up to 200 hours of lamp time.
Q: Can the bulb be replaced in the field?
A: It is not designed for field replacement. Return the unit to the factory if the output is
reduced or the lamp will not illuminate. Call Customer Service for assistance.
Q: How much does a replacement bulb cost?
A: It depends on the circumstances and what else is out of specification at the time of service.
You will be quoted the costs for repair of your FA Light Box before any work is begun.
Q: Can I get a replacement barrier filter if mine is lost or broken?
A: Yes, contact Customer Service for a quotation.
Q: Can the FA Light Source be returned for service without returning the whole RetCam II?
A: Yes, the FA Light Source is a module that is removable by a person with the skill level of a
nominal biomedical technician. Be sure to package it as a sensitive medical instrument with at
least 3” of padding on all sides in a sturdy box, sealed well, shipped insured for USD $20,000.
NOTE: Clarity can send appropriate packaging material to you if needed.
Q: My FA Light Source turns itself off. It comes back on in a few minutes, or if I turn the
power off and back on. What’s wrong?
A: The temperature sensing circuit is protecting the Xenon lamp. It may not be working
properly. The FA Light Source may need repair and it may be a warranty issue regardless of the
age of the unit. Contact Customer Service for advice on how to clear the condition or to
schedule service.

3.4 Servicing the Interior of the Cart
WARNING: Removing the back panel should be done by qualified technical
personnel only. Maintenance personnel should be familiar with the usual
precautions regarding the service of electronic and electrical equipment. In
addition, the RetCam II contains an uninterruptible power supply (UPS) that
contains batteries. The UPS will NOT be disconnected when the main power plug
is removed from the wall. Precautions must be taken to ensure that the UPS is not
energized before performing maintenance inside the cart.
The computer, Light Box, Fluorescein light source (option) and image printer (option) are
modules that can be removed from the back of the cart if necessary. Make note of the cable
connections before removing a module.
Contact Customer Service for help troubleshooting problems to the module level before
removing any modules. Many problems can be traced with the help of substitute harnesses and
voltage measurements made in the cart without removing any modules.
Service to the UPS requires removal of the image printer (if present), and disassembly of the
base cover. Contact Customer Service for detailed instructions for removal and replacement of
the UPS if service to the UPS is required.
WARNING: When doing this level of service, Electrical Safety Retesting of
the system is required to maintain compliance with IEC requirements.
Contact Customer Service before beginning.

1.
This service method applies to RetCam 120 and RetCam II, all white handpieces.
2.
If the handpiece doesn’t make a soft motor sound when the focus buttons are pressed,
troubleshoot the electrical problem first.
3.
The simplest way to troubleshoot a focus problem is to operate the handpiece without any lenses
attached.
4.
Pull the fiber optic cable only from the lightbox (focus to the room lighting). With a live image on
the screen, find the distance at which a target (business card, zip disk, cotton swab, finger) is in
focus. Measure or estimate the distance from the front surface of the camera.
5.
The total range of focal distance is -0.15” (– 4 mm) which is just inside the front surface, to 3.3”
(approximately 85 mm) from the front surface.
On the RetCam II system
To move the focal distance closer,
press the left membrane
‘focus closer’ button.
PN 04-03-023 Rev A, Service Manual, RCII
To move the focal distance further,
press the right membrane
‘focus further’ button.

RetCam Handpiece Focus Method 800138, Revision A
Appendix 12
6.
[For RetCam 120 only, press the rocker switch on the light box in the up position to focus closer,
and the down position to focus further. It is preferred to use the rocker switch on the light box
because the footswitch alternates direction.]
7.
The focal distance in this configuration to preset for use with an ROP D1300 or Children’s B1200
lens used for imaging the retina is approximately 24 mm (1”). The focal distance to set for
imaging the anterior segment is approximately 12 mm (0.5”).
8.
It takes approximately 62 seconds for the focus motor to travel the full range.
9.
It takes approximately 13 seconds to go from retinal to anterior imaging, holding the ‘focus
closer’ button. Conversely, it is approximately 13 seconds holding the ‘focus further’ button to go
from anterior segment back to retinal imaging.
