Sometimes it may be a situation in which the device is "Ultra DreamStalker" night works extremely rare or, on the contrary, is triggered excessively often. As the practice of solving such problems, they often arise due to variety of reasons, the vast majority of cases not directly connected with the correctness and performance of the device itself. Most often such cases are caused by incorrect settings of the instrument is not corrected to the right, and in the opposite direction. However, occasionally there are issues of a different kind. For example, sometimes the sensor movements of the eyes partially closed edge of the cloth masks, a cut in which the production was made a little less or made with the offset relative to the position sensor. This article was specially written in order to help you find the root of the problem and restore normal operation of the device.
To resolve the problem, you should first test the sensor eye movements. To do this, connect to the device via wifi and do a factory reset to set the sensor sensitivity and other settings as "default". Please wait until the device will boot and will give a melodious tone. Again connect to the device via Wi-Fi and turn on the test mode of the sensor movements of the eyes. The device at the same time he will disconnect your wireless connection and You should be carefully, without pressing the button, wear a mask device on the face. The device will make different sounds, which should not be ignored. The room should be bright light, especially from light bulbs. Slight backlight type of light or a weak bulb at a sufficient distance. You had better lie down on the bed in position on your back and close your eyes. Now listen to what sounds are emitted by the device. In the case of normal operation it should be a separate very short bleeps. If you hear them, try to slightly squeeze the mask with your hand to the right eye, and then try a little to move the mask from the eyes. In both cases, you should hear only a short bleeps, which correspond to the detected movements. Place the mask exactly and try to relax and calm closed eyes to eyelids twitching and trembling. If the device ceases to emit sounds, it is possible to make an unambiguous conclusion that the motion detector eye works absolutely fine.
Now consider the situation when test mode the sensor will signal an error. In contrast to earlier devices of the series "DreamStalker", the instrument version of the "Ultra" uses advanced algorithm for testing gauge, which measures the departure of the sensor signal in the test area. There are two different types of signal errors.
The first error signal is a constant triple signals "pee-pee" with a pause between them. Such a signal means that the sensor sees nothing in front of him, so his signal goes into the space, or the signal is not emitted at all, or not accepted reflected signal. In norm it can only be removed when the mask is placed on the surface of the table up sensor. If such a signal is heard when the mask is worn on the face, it can be assumed that the closed edge of the mask is dirty or one of the three holes of the sensor located on the side of the right eye. Perhaps mechanical was damaged one of the sensor elements. "Treatment" is simple – it is necessary to slightly undercut the edge of the fabric covering the sensor and clean with cotton swab moistened with alcohol, the "eyes" of the sensor. Mechanical damage requires the repair or replacement of the damaged element of the sensor.
The second error signal is a constant private long signals "PI and" with a pause between them. If You hear this beep, it means that the sensor takes too strong reflected signal. This can occur either when too tight a grip on the mask to the surface of the eye, or in the case when the holes of the sensor hangs any mask element, which is a reflection. This may be the edge of the soft gasket or otogrevshis the edge of the fabric of the mask overhanging the openings of the sensor movements of the eyes. Despite the fact that the mask is made of black fabric, the wonderful sensor signal is reflected from the surface of that tissue. To resolve this problem easily with the help of small scissors or a sharp knife.
What to do if the test is absolutely fine and the device works very rarely on eye movements night? All people are different, eyes are located at different distances from each other, eye movements during sleep are stronger or weaker, the skin of the eyelids may have a different degree of reflection due to excessive dryness or greasiness, etc. for such special occasions is for setting the sensitivity of the sensor eye movements, available through the web interface as all other instrument settings. The standard setting of the sensitivity of the sensor is "4" (not to be confused with quantity sensitivity). This level roughly corresponds to the sensitivity of the early instruments from the series "DreamStalker" (in which she couldn't be adjusted). To increase the sensitivity of this setting should reduce, not increase! Put – "3" in the morning and look at the statistics of positives. Should be monitored a significant increase. If it is still not enough, try the value 2. Also in the device there is a setting related to the sensitivity of the sensor only during the monitoring of the dreaming, called "quantitative sensitivity of the sensor eye movements". This setting shows the number of times should be detected by the eye movement over a certain period of time for actuation of the device. To increase the sensitivity to eye movements this setting should also decrease, not increase! The default value is 5, it can be reduced or, conversely, to increase (zoom only when necessary to reduce the sensitivity).<
