一, features: 1, a U.S. patent magnetic induction chip technology, the technology has been applied to the U.S. military, their military vehiclesequipment used in field combat tanks. 2, a high-precision, powerful anti-magnetic interference from weather, geography environmental impact; 3, do not have satellite positioning or movement of road vehicles can be informed of the directionangle of deviation, is a user-friendly car navigation devices with the initiative. At the same time have been GM, FORDother world-renowned automobile manufacturers used as a designated product. 二,function: 1, the Chinese clearly shows that direction, supplemented by point of view, accurate indicator readings to ± 1; 2, insideoutside temperature display (range: -20 ℃ -80 ℃); 3, time, dateweek calendar display; 4, Qiangci interfere with voice prompts; 5, backlighting at night, that is inconsistent with that-and long-mode; 6, power-saving mode, shut down automatically display; 7, equipped with long-lasting lithium batteriescar power adapter; 三, debugging: Commissioning the magnetic field so, please ensure that your product affixed to the windshield, in an open space on. (Open space as long as the size of normal cars can be Zhuanquan). 四, debugging steps: 1. SET by three seconds will be automatically entered debug mode, the display will "set". 2. ADJ began by commissioning, the screen will appear, "the turn" words. 3. Launch vehiclebegan slowly Zhuanquan place, two laps to clockwise direction. Please Zhuanquan process in 20 seconds to 30 seconds to complete. 4. Then ADJ completed debugging 五, the compass: 1. After the completion of commissioning, the compass data (Chinese shows the directiondegree of precision) will be displayed properly on the screen. 2. In sleep mode, according to MODE will be re-activated. LCD display direction, point of information. 3. Hold down the MODE three seconds, it will then go one hour mode. (One hour will not go to sleep mode) 4. To save power, within 10 minutes if not press any button, will automatically enter sleep mode. LCD does not display information at this time. 六, timeweeks show: 1. Compass mode, according to MODE weeks into the timedisplay modes. 2. ADJ switch by weeks or date show. 3. Such as 10 seconds without any operation, will be automatically returned to the compass mode. 七,Temperature show: 1. Option by the MODE button thermometer into the model. 2. Keys for the products behind the option of indoor / outdoor temperature display. 3. Convertible by ADJ temperature display units. (℃ or Fahrenheit) 4. Such as 10 seconds without any operation, will be automatically returned to the compass mode. 八, luminous lighting: 1. LIGHT will be provided by five seconds the night lighting; 2. LIGHT5 hold down the seconds, could provide one hour luminous lighting (that is, long-mode) 九, attention: 1. To get accurate readings of the direction point of view, the products must be completed before the use of magnetic field debugging. Who have strong magnetic field interference, show that there will be "interference". 2. This device for precision instruments, users should not arbitrarily demolishedthe demolition if the user, not manufacturers warranty. 3. If the new products to replace batteries, or products from the car has been good for Commissioning other car, it needs to re-commissioning. 4. Warranty period: from the date of the sale since 2001. use: With sucker stentstickers, can be directly adsorbed car windscreen, or paste can on the dashboard.
