The error "System Initialization not complete" on the Zeiss Humphrey HFA II-i series machine likely indicates a failure in the initialization of the RAM disk during startup. This issue is known to occur in instruments with the new CPU (P/N 55392) using software revision 3.4. It results in the system failing to reach the main menu and displaying a blank screen without other failure indicators. Updating the software to revision 3.4.5, which includes a new RAM disk initialization routine, is the recommended solution. If the problem persists, further troubleshooting using the service manual is required.

General Information Humphrey Field Analyzer II - i Configuration Parameters Configuration parameters can be entered and stored in the system by the user. This data is stored on the hard disk. Calibration data also is stored on the hard disk. There is the possibility that this data may become altered or erased during servicing of the instrument.
Page 21 To prevent personal injury and damage to the instrument: Use only the power table recommended by Carl Zeiss Meditec. Do not place the instrument on uneven or sloped surfaces. For stability of the power table, strictly adhere to the following guidelines: Ensure that the instrument is secured to the power table with the screws provided.
Page 22: Internal Layout
General Information Humphrey Field Analyzer II - i Do not rub the inner bowl surface while attempting to clean it; rubbing will cause a noticeable polished area in the bowl. Do not touch the glass surface of the projection lamp with your bare fingers. Any oil, dirt or grease on the lamp can shorten its effective life and diminish light output.
Page 23: Gaze Tracking
Humphrey Field Analyzer II - i General Information 1.7.2 Gaze Tracking The HFA II - i uses two systems for measuring patient fixation: the standard Heijl-Krakau blind- spot monitoring and the IR Gaze Tracking System. Both methods can be used, either together or alone, or they can both be turned off, as required.
Page 24 General Information Humphrey Field Analyzer II - i Spikes that appear on the Gaze Graph (Figure 1-6) are analyzed as follows: Upward spikes indicate that the patient has lost fixation; • a spike that reaches the top horizontal line (or higher) indicates 10 degrees (or more) off fixation;...

Page 26: Head Tracking / Auto Pupil / Vertex Monitoring
General Information Humphrey Field Analyzer II - i 1.7.3 Head Tracking / Auto Pupil / Vertex Monitoring These three features are dependent on the Gaze Tracking system. If Gaze Tracking has successfully initialized, any of these three features can be utilized. Head Tracking The Head Tracking feature is designed to lessen the appearance of a trial lens artifact image when the patient's eye is off center in relation to the center of the trial lens holder.
Page 27: Hfa Ii - I Light Intensity Fundamentals
Humphrey Field Analyzer II - i General Information 1.7.4 HFA II - i Light Intensity Fundamentals The HFA II - i uses one detector mounted at the end of the turret to measure both spot and bowl intensities. The projection lamp voltage is controlled by software to set maximum stimulus brightness.
Page 28 General Information Humphrey Field Analyzer II - i addition, the new board features components selected to ensure ease of parts availability, particularly integrated circuit components. The HFA II - i CPU PCB uses an IDE hard drive controller. The HFA II CPU PCB uses a SCSI hard drive controller.
Page 29 Humphrey Field Analyzer II - i General Information Many of the unique functions that the HFA II CPU PCB supported are now included in the HFA II - i Backplane PCB. The functions of the Backplane PCB include; the patient switch, touch screen, camera frame grabber, and video.
Page 30 General Information Humphrey Field Analyzer II - i The HFA II - i has a larger capacity power supply to provide the additional Vcc power required for the HFA II - i. The HFA II - i uses a new Motor Driver Board (MDB). The new MDB will ensure longer component availability.
Page 31 Humphrey Field Analyzer II - i General Information The external connections to the HFA II - i are considerably different from those of the HFA II. Two USB and a network port have been added to the HFA II - i. These ports are inoperative at this time.
Page 32: Peripherals

Page 110 Adjustment / Calibration Humphrey Field Analyzer II - i If the service call requires both Before and After verification of the light intensities, a Calibration Shift Worksheet must be completed to determine the difference or ‘shift’ in light intensity. Refer to Appendix I, Service Forms. Preparation: Depending on the instrument model, perform the preparation steps for models 740i / 750 i or for model 720i.
Page 111 Humphrey Field Analyzer II - i Adjustment / Calibration Set the light meter to position 1. From the Main Calibration menu, select VERIFICATION, then INTENSITY/SPOT RATIO. Select either BEFORE or AFTER, as appropriate. NOTE: The Mfg and QA selections are for manufacturing use only. Selecting either of these two buttons will set tolerance values which are much tighter than those required for field service evaluation.
Page 112 Adjustment / Calibration Humphrey Field Analyzer II - i White Bowl Intensity Verification: 12) Select #61/BOWL. The bowl lamp warm-up period will begin. (You may cancel from the warmup period when the voltage stabilizes at >20%.) After the warmup period ends or when the voltage reading has stabilized: 13) Enter the voltage reading via the ten-key pad.

Humphrey Field Analyzer II - i Troubleshooting Introduction The troubleshooting aids in this section provide the Field Service Engineer several aids for problem diagnostics of the HFA II - i. As Field and Repair Center experience identifies recurrent problems and appropriate diagnostic processes, the section will be expanded to include additional troubleshooting aids.
Page 154 Troubleshooting Humphrey Field Analyzer II - i - the problem presents itself continuously. Solid Failure - the problem is intermittent in nature. Usually a specific Intermittent Duplicable sequence of events reproduces the intermittent symptom, although occasionally these problems may be random in nature. By performing the proper sequence of events, the problem can usually be reproduced.
Page 155 Humphrey Field Analyzer II - i Troubleshooting Substitute the Failing Assembly. Once you have deduced which assembly is at fault, or is suspected to be at fault, it should be substituted with a known good assembly. Confirm the Repair. After an assembly is replaced, confirmation should be made by reinstalling the failing assembly to witness the original symptom.
Page 156 Troubleshooting Humphrey Field Analyzer II - i Solving Intermittent Non-Duplicable Failures: These failures present the greatest difficulty to the Field Service Engineer. The most effective means for resolving these types of problems requires careful thought and the utilization of all available resources that the Field Service Engineer possesses.

Page 317: Database Utilities
Humphrey Field Analyzer II - i Appendix K The floppy-only option will allow the instrument to save only to the floppy disk drive. This enables the operator to continue to save patient exams until a service technician can repair the hard disk drive problem. The floppy-only option would normally be selected if the Recover option has failed, the user has just completed a test and immediately needs to save it to disk, or does not currently have the time to wait for the Recover option to complete.

Appendix K Humphrey Field Analyzer II - i If the rebuild fails, try viewing the diskette on a PC. Proceed to the “A” drive and attempt to look at the directory. You cannot view individual patient files, but should be able to see the directory. The directory will consist of files like PATS.DAT, PATS.IDX, PDB.DAT, RXS.DAT, etc.

Find out when the last Preventive Maintenance (PM) service call was performed (if applicable). If a PM is due, or will be due shortly, be prepared to perform this task in addition to the repair.
Page 352 Also, the number of "No Problem Found" PCB's returned to the Carl Zeiss Meditec Repair Center is greatly reduced. Confirming the repair to the customer often helps to bolster confidence in your abilities. To avoid repeat service calls it is especially important to confirm intermittent problems.
Page 353 Page 4 GEN-004B Solving Intermittent Non-Duplicable Failures These failures present the greatest difficulty to the Field Support Engineer. The most effective means for resolving these types of problems requires careful thought and the utilization of all available resources that the Field Support Engineer possesses. It is important that before replacing an assembly, good solid rationale for its replacement be developed and a backup plan devised in case replacement of the assembly does not affect the symptom.
