Rista: FAQ

General questions

Q: What is the difference between "Rista-EPD", "Rista-EPDm" and "Rista-mini"?

A: "Rista-EPD" is mainly intended for stationary operation, and it cannot function without a computer. "Rista-EPDm" and "Rista-mini" are autonomous portable devices most suitable for operation with the patient at home. "Rista-EPDm" totally replaces "Rista-EPD" if connected to computer. It also provides auricular and Voll diagnostics when used with "Rista-EPD" software. "Rista-mini" provides only Nakatani measurement technique.

Devices' characteristics are presented in the following table:

Q: What is the best choice "Rista-EPDm", "Rista-mini" or "Rista-EPD"?

A: The most comprehensive choice is the "Rista-EPD" system, including it's input unit together with the "Rista-EPDm" device. While one of the physicians carries out an inspection at patient's home, another one works with a complex at hospital. Another variant is a software system "Rista" together with "Rista-EPDm" device. This configuration as much as possible satisfies the demands of an individual SCENAR-therapeutist. The "Rista-EPDm" device is least expensive variant. You can purchase the

"Rista-EPD" software later. Finally, the "Rista-mini" device is intended for mass user.

Complicated support of Voll and auricular techniques has been excluded from this device, which resulted in reduction of it's weight, size and price. Nevertheless, the device can generate valuable SCENAR and OLM-1 treatment hints in autonomous mode. If connected Rista-EPDm and Rista-mini to the computer, you can save measured data in the database and print it.

Methodical support

Q: What is the difference between the techniques realized in "Rista-EPDm", "Rista-mini" and "Rista-EPD"?

A: The treatment hints of "Rista-EPD" and "Rista-EPDm"/"Rista-mini" are based on different approaches. In the "Rista-EPD" system the hints are based on the criterion of maximum difference of meridians' conductivity. The hints of "Rista-EPDm" and "Rista-mini" are based on principles of small asymmetry.

Q: How to determine, whether the measurements are correct?

A: It is necessary to remember that it is almost impossible to get "overestimated" results accidentally. And the "underestimated" results can be obtained in the following number of cases:

• The measurements took place at an incorrect positions on the skin;
• Prolonged influence of electrical current at the position of point before the beginning of measurement;
• Electrode has been taken away form the skin earlier than necessary;
• The cotton wool has been non-uniformly moistened.

Therefore, single glitches upwards on the Nakatani map, most likely, represent correct data.

The single glitches downwards, (especially together with the small dispersion of other measurements), need the measurement to be repeated. If the low value of an individual corridor has been obtained and the dispersion of values is in-significant, it can testify that measurements have been performed at incorrect positions. You should remember, that patient must take off his socks and braslets or wristwatches not earlier then 10-15 minutes before the inspection.

Q: How often is it possible to make measures (before and after SCENAR-therapy session,in an hour, in a day)?

A: It is possible to take measures before and after SCENAR-therapy session, but results of these measures can be rather different, because of SCENAR-influence. If there was no SCENAR-influence, and there was a little time interval between measures, readings shouldn't change strongly. But if they do, it may be concidered with surgeon's mistakes (making measures out of points, etc.).

Here you can see a result of readings changes research.

Q: Will the techniques used in "Rista-EPDm" and "Rista-mini" be improved?

A: Currently, we are working on patenting of several ideas used in techniques of "Rista-EPDm" and "Rista-mini" devices. After reception of guard documents, the techniques will be expanded. All users of "Rista - EPDm" and "Rista-mini" devices can upgrade it's software with no charge for all devices, irrespective of purchasing time and complete set.

TECHNICAL ASPECTS

Q: Does the software of "Rista-EPDm" and "Rista-mini" devices improve? How can I get a new version of software?

A: The software of both devices and the computer program is permanently being enhanced.

At the same time we are trying to guarantee it's succession and compatibility. All versions of computer program correctly work with all variants of "Rista-EPDm" and "Rista-mini" devices. The latest version of computer program and a firmware for the "Rista-EPDm" and "Rista-mini" devices can be updated at www.okbritm.nm.ru. There you can find out how to program the firmware into device. Also you can find there some additional information.

I. "Rista-EPDm"

Q: During the charging the device is heated, also one of the corners of the device's screen darkens. What is the reason?

A: It is normal operational mode of the device. If the indication meets the data of the passport, there is no reason for anxiety.

Q: Can I start charging accumulators is they are not fully discharged? Can I interrupt the charging of accumulators if they are not fully charged?

A: The uncompleted discharge/charge cycles result in an accumulators' fast failure, therefore it is not recommended to interrupt charging or discharging without emergency reasons.

Q: The device can not be switched on by buttons. The device also doesn't switch on even if it is connected to charging device. What should I do?

A: This situation is described in the passport and can happen, if the device with almost discharged accumulators has not been used for a long time. Connect the charging device to the mains and then to the device. Press the "Reset" button through a hole in a bottom cover of the device for a period of about 10 seconds. If the device after releasing of the button doesn't start, it is necessary to repeat the procedure, increasing the time of press-ing up to 20, and then up to about 1 minute. If the device is not working in this case, it is necessary to perform maintenance service. For preventing a similar situation the device should be charged before a long pause (more than 3-5 days).

Q: How long does the full charging of accumulators lasts? My device has stopped charging after 30 minutes (1,5 hours). Why?

A: It depends on several reasons: capacity of the accumulators, consumed and charging current, ambient temperature. Normally charge lasts from 10 to 16 hours. If the "Rista-EPDm" device is disconnected from the charging device or reports about completion of the charging process in considerably short time, it is, as a rule, due to failure of accumulators. Also premature termination of charging can take place if the accumulators were discharged to 'zero' before charging start. In this case it is necessary to switch off the "Rista-EPDm" device and then repeatedly switch on charging by connecting the charging device to it after 2-3 hours.

Q: How long should the device work with completely charged accumulators?

A: It depends on the several reasons (as well as the duration of charging): capacity of accumulators, current consumed by the device, ambient temperature, operational mode (continuous / non continuous). Average time of discharge is about 8-12 hours. If the duration of operation after a full charge has reduced to 6 hours or less - the accumulators need to be replaced.

Q:How to upgrade the Rista-EPDm firmware?

A:In order to upgrade the internal program (firmware) in the device:

1. Determine, wheather your device supports firmware upgrade.
2. Download new firmware from the Rista-EPDm tech. support site.
3. Program new formware into the device.

To determine, wheather your device supports firmware upgrade or not select item "Version" in it's menu "Parametars". Right bottom to the inscription "RistMEGA" there will appear a value.

• If it is 128 - firmware upgrade is possible.
• If it is 103 - firmware upgrade is NOT possible.
• If there is no item "Version" in the menu "Parameters", or serial number of the device is less than 50, firmware upgrade is NOT possible.

Also firmware upgrade is not possible for Rista-MINI devices.

II "Rista-mini"

Q: The device is connected to the computer, but the program can't find it. What is the reason?

A: First of all, check whether the device is switched to the communication mode. Secondly, pay attention whether the device is giving a quintuple sound signal. In this case you need to replace the battery.
