1. Introduction
1.1. Outline of the Instrument
The HUVITZ Digital Refractor HDR-7000 system is a computerized auto refractor used for subjective refraction by regarding the patient’s accommodation power and facilities. Also the Digital Refractor is used for detecting and measuring any anomalies in binocular vision such as muscle balance, binocular balance, aniseikonia, fusion, and stereopsis. The subjective refraction can be practiced on the basis of objective refraction that is done by using an Auto Ref/Keratometer(RK) connected to Digital Refractor. The examiner can do their optometric practice in pretty short period of time with ease with the aid of fully integrated and automated Digital Refraction System where every instrument for the refraction is interfaced and controlled by one touch of button on the Digital Refractor.
HDR-7000 system includes a refractor body, an operation panel, and a junction box.
The refractor body has more than a hundred lenses and serves as an automatic lens-loading unit. It is connected to the operation panel via the junction box and is controlled by the operation panel.
The operation panel is the main controller of HDR-7000 system. It controls the refractor body, chart-presenting device, and also receives data transmitted from Auto Ref/Keratometer(RK), Auto Lensmeter(LM), or a PC interfaced with Digital Refraction System. And also it has a built-in thermal printer with it.
The junction box serves as a power supply to the Digital Refractor and the Operation Panel. And it provides communication ports for interfaced instruments such as Chart Projector or Auto Ref/Keratometer.

3. Features
1. Using standard protocol CAN, all appliances are connected by daisy-chain line. As a result, HDR-7000 system makes office environment more clean and modest.
2. Because 1 or more(up to 8) HDR-7000 system and 1 or more(up to 4 each) LM/RK are connected without any additional equipment, high utilization and low cost can be achieved.
3. Compatibility between Huvitz products enables to manage patients’ data more easily. For example, not only S/C/A value but also KER, PD data are gathered automatically from RK. Also S/C/A value, prism, additional power data are gathered automatically from LM. All of these data are presetting to the HDR­7000 system without manual control.
4. HDR-7000 system supports near PD (48~80mm) and near working distance (50~74cm), so you can execute perfect near vision tests.
5. Separated Dual Cross Cylinder lens and automatic occlusion during lens change makes more accurate test result.
6. For accurate Phoria and Strabismus test, HDR-7000 system support prism measurement by 0.1D unit up to 20D unit. Also automatic occlusion during prism change minimizes the examinee’s eye adaptation.
7. On-line guide assist examiners to finish test fast and convenient.
8. To analyze result at a glance, HDR-7000 system supports table and graphic result display facilities.
9. Built-in high-speed printer saves additional space to install printer equipments and prints test results extremely fast.
10. PRESET faculty defers physical lens change until all the necessary lenses are
------------------------------------------------------------------ HDR-7000 Operator’s Manual
properly set at any states.
11. HDR-7000 system supports wide visual acuity up to 40’
12. Touch Screen supports various functions of the Operation Panel by using touch-pen with ease.
13. Dialog-driven menu and simple function keys make it easy to access complicated faculties. In addition, using [SHIFT] or [ALT] key combinations, various options and faculties are easily accessed and executed.
14. To escape from the previous dialog as fast and convenient as possible, [ESC] key is supported.
15. For professional examiners, 18 visual acuity tests, 24 monocular/binocular balance tests, 35 user defined unit tests are supported. Also a Standard and 10 user-definable pre-programmed sequences are supported.
16. The CDR-MATE program running on a PC which supports PC-connectivity and PC-style printer interface is optional.
17. Various binocular balance tests and phoria tests are supported. Advanced graphical guide systems for such complicated tests are also available.

4. Notes for Using the Instrument
1. Do not hit or drop the instrument. The instrument may be damaged if it receives a strong impact. The impact can damage the function of this instrument. So handle with care.
2. Install this instrument on a level, stabilized table with no vibration to keep it normal state.
3. Exposure to direct sunlight or very bright indoor lights can influence the results of measurements.
4. If you want to connect this with other equipments, consult the dealer.
5. Sudden heating of the room in cold areas will cause condensation of vapor on the protective glass in the measurement window and on optical parts inside the instrument. In this case, wait until condensation disappears before performing measurements.
6. Keep clean the objective glass of the examinee side. If it is stained with other substance, it may cause an error or inaccurate measurements.
7. Don't use organic solution such as thinner, benzene, etc. to clean the surface of this instrument. It may damage the instrument.
8. Disconnect the power supply and consult the dealer in case of smoke, strange odors, or noise during operation.
