Q: What shall we do when a problem that could not be solve occurs
to the product?
A: Record product model and software version number and submit
detailed problem description to our technical
support engineer for analysis. Detailed description will be very
helpful to our analysis.
Q: What shall we do when the mobile device has no video output?
A: 1. Check the power status of the device. If only one blue
indicator is lit up, it indicates that the device is still in
standby mode and not powered on; at the same time, check if red or
yellow cable of the main power is supplied
normally; If not, the device cannot be started.
2. Check if the display is powered and if the display video is
switched to AV status.
3. Check the connection status of the video output cable and
display.
Q: What shall we do when the mainframe video input interface is
different from the camera input interface?
A: a 4-pin interface is used for the vehicle device. BNC interface
or air interface is used for the camera. If inconsistency
is found, please use an adapter or connect it to a standard line
defined as the line sequence for the vehicle device.
Q: What shall we do when no video is reported via 3G/4G?
A: press the "INFO" key to enter the System Information page, where
you can check if the SIM card is present, inspect
signal intensity and dial-up status, and check if the antenna is
properly contacted. Then, check if the SIM card has
traffic and replace it will a new one to re-check it. This is a
most basic judgment criteria. If a signal is available, while
dial up fails, check if the center number and port are set
correctly. Then, check if the device number is unique.
