Liquid or particle enters into the device;
The device is damaged due to falling from a high place or incorrect operation.
13. LCD
Protect the LCD from dropping. If the LCD does fall and shatter, do not touch the
liquid flowing out of the device. Do not heat or scratch the LCD.
7. What is the maximum charging time?
The device will be fully charged in 3–3 ½ hours under standby mode. The device
can also be charged when in use, although charging time is longer. It is normal for
the unit to heat up while charging.
8. What advantages does your GPS hardware have?
It supports fast lock-in, stable signal, service at no charge, a detailed map for
each city, voice navigation for the whole journey, intelligent route layout,
Microsoft Windows CE.net operation system, audio and video file support, Mp3/
MP4 and picture browsing; SD /MMC card support; 3.5 inch TFT touch screen with
65K colors, internal GPS antenna and high capacity rechargeable Li-polymer
battery.
9. Normally, how many satellites can the GPS receiver capture?
Normally, most GPS receivers can capture 8-12 satellites.
10. Why don't some of the WMA files play?
Software is used to decode WMA files. Music that was not obtained legally may
not be supported by this software. Make sure that the music is obtained legally.

11. How can I keep the device from crashing when turning on the car?
Disconnect the GPS unit from the adapter to avoid device crashes during car
startup.
1. How does weather affect the instrument?
Severe weather like rain, thunderstorms or lightening will cause weak signals,
which will result in unstable operation of the instrument.
2. What factors may affect the GPS signal?
Close proximity to military bases. For security reasons, the signal precision for
civilian use is lower than that of the army. Therefore, precision of positioning
may be reduced.
Weather factors (inclement weather may reduce the intensity of signals and
result in unstable orientation).
Positioning of the GPS unit within the vehicle:
o Other devices may emit electric, electromagnetic, or wireless waves or
have a strong magnetic field.
o Placing the device close to the windshield will help maximize the signal
by minimizing interference from tall buildings, cars, heat insulation covers,
metal objects and trees.
3. Why does the device not receive signal inside buildings?
The GPS can't be used in buildings because the signals are easily obstructed
by buildings and metals, and they can't penetrate through the walls of buildings.
4. Does the windshield affect the GPS signals?
If the windshield contains metal, it will have some effect on the GPS.
5. How long does the GPS take to position after being switched on?
On average, the device will take approximately 1 minute to calculate your current
position in an open space where interference is minimal. In general, it takes
about 5 minutes or less, as in accordance with standard GB/T 19392-2003-5.3.
6. What is the maximum battery time?
The device will run smoothly for a maximum of 3-4 hours with the screen brightness
set to 50%.
