1. In the manual does not explain what the signal indicator shows at all: GPS signal? Mobile? Battery? What is blinking, which means lit steadily?
2. It will not explain how to set the time, it found only one command for "time zone". However, both appear to summer and winter time. That also use this command at all the time is set, you realize when you've done it once. If you set anything, the time count starts from 00:00 clock.
3. The label "Incutex" has been stuck on it totally unloving and wrong, probably quickly at the very end. This does not exactly reputable. Normally, the manufacturer's name is printed on it, not glued.
4. Worst: The reply SMS works after twice not to call. Even after reset and re-entering all data. Interestingly, the SOS button anyway. Enigmatic.
The administration via SMS work, the GPS data are also very ok. But I think I'll send back the device (s. Point 4).
Too bad that there is little devices of this type on the market.
