Installation Preparation
2.1 Installation Technical Requirements
2.2 Understanding the Installation Environment
2.3 Vehicle Condition and Related Electrical Information
2.4 Vehicle Power Connection
Relevant personnel should be familiar with the product's features, applications, and
overall composition.
Relevant personnel should have knowledge of vehicle circuits, structures, and
commonly used installation methods for in-vehicle devices.
Before equipment installation, relevant personnel should have a clear understanding of
the vehicle model, installation position of the device, cable types and lengths required
for different vehicle models, and the list of commonly used auxiliary materials. This
ensures the smooth completion of equipment installation and debugging.
Con󽗉rmation of vehicle information is the basic prerequisite for successful installation
and the assurance of role allocation to avoid vehicle damage. For each component, the
next step can only proceed after clear con󽗉rmation, with con󽗉rmation by the vehicle
responsible person and the installation personnel for each operation.
(1) Check for any damage to the vehicle's exterior and interior components.
(2) Check if the vehicle can be started normally.
(3) Check the status of the vehicle's power supply system.
*Note: Con󽗉rming the above information is crucial. Installation can only proceed after
con󽗉rmation of normal conditions.
It requires the operation of professional installers. The following mainly describes the

7
method of connecting the vehicle's power supply according to the product's power
cable requirements.
(1) Tools required: Multimeter.
(2) Selection of Power Connection Location
When the vehicle is parked and ignition is OFF, use a Multi-meter to check if the
circuit is powered. If it is positive, it is determined to be a constant power supply, and
then measure the voltage.
When the vehicle is parked but the ACC is ON or ignited position, use a Multi-meter
to check if the circuit is powered. If it is negative when ACC is OFF and positive when
ACC is ON, it is determined to be the ACC cable, and then measure the voltage.
(3) Voltage Measurement at Power Connection Point
Constant Power Supply: With the vehicle is parked and ignition is OFF, use a
Multi-meter to measure the voltage of the constant power supply cable, which is
approximately 24 V or 12 V. If multiple cables have voltages within this range, select the
cable with higher current as the constant power supply connection cable.
ACC: When the vehicle ACC is in the ON position or ignited state, use a multi-meter to
measure if the voltage is 24 V or 12 V. If it is 0 in the OFF state and 24 V or 12 V in the
ACC ON position or ignited state, select the cable as the ACC power supply connection
cable.
*Note: When connecting the power supply, measure the positive and negative
terminals of the power supply 󽗉rst with a multi-meter to avoid errors.

Installation
4.1 Installing standard SIM Card and Memory Card
Installing the standard SIM card and Micro SD card as shown in the following diagram
(pay attention to the insertion direction of these cards). During installation, make sure
it feels smooth and flexible. When pushing the card, you should hear a clear "click"
sound, indicating that the card is correctly inserted. If you feel significant friction or
resistance during installation, it means the card is inserted in the wrong direction. In
such cases, promptly remove the card to avoid damaging it.
If the Micro SD card and standard SIM card are too small to be inserted into the slot
manually, you can place the card into the slot and then use the included pry tool to
push it in.
Insertion of standard SIM card and Micro SD card
*Note:
(1) Due to the operating temperature range of the device from -20 ° C to +70 ° C, the
Micro SD card and standard SIM card should be able to work properly for an extended
period in harsh environments. Specifically, the metal contacts on consumer-grade
Micro SD cards and standard SIM cards are prone to oxidation under prolonged
exposure to heat, humidity, or salt spray conditions. Frequent insertion and removal
of cards can lead to contact wear, and the card slot can experience deformation or

13
bending under constant pressure, resulting in poor contact. Therefore, if you are
using a standard SIM card, for industrial equipment, industrial plastic or ceramic M2M
cards (MP2/MP3/MS1 grade) with a working temperature range of -40 ° C to 105 ° C is
recommended. If using a Micro SD card, an industrial-grade Micro SD card should be
used, which offers strong stability and can be used within a wide temperature range
(-40° C to 85° C). For safety purposes, when purchasing the device, it is recommended
to use Micro SD cards that have been verified by our company. If you choose to
purchase unveri󽗉ed Micro SD cards, there may be a risk of damaging the device, thus
a󽗈ecting its lifespan.
(2) Before installing the standard SIM card, please check the metal contact surface of
the standard SIM card for any dirt (such as dust, 󽗉ngerprints, or watermarks). If there is
any, use a non-woven cloth or rubber to clean the surface.
(3) When installing the standard SIM card, avoid touching the metal surface of the
standard SIM card with your hands to prevent contamination from dust and sweat.
After installing the standard SIM card and Micro SD card, tighten the card slot panel
and the screws.
Once the standard SIM card and Micro SD card are installed, remove the camera lens
protective 󽗉lm.
4.2 Choice of Installation Area for the Main Unit
The installation area requirements for MC402 are as follows:
(1) The device must be installed in the middle of the windshield. Typically, it is
installed in the area above the center line of the windshield, in the vicinity of the
rear-view mirror. If it is not possible to install the device in the middle as required, a
deviation of less than 5 cm to the left or right is allowed (the deviation of the device
relative to the center line of the windshield is calculated using the center line of the
front lens).

14
(2) The lens of the road condition monitoring camera must be within the working
range of the left and right windshield wipers (ensuring that the screen of the road
condition monitoring lens is clean and free from stains).
(3) It is recommended to avoid installing other electronic devices, including smart
rearview mirrors, electronic tags, etc., around the device, as it may a󽗈ect the device's
positioning signal.
The installation position should ensure that the main unit does not obstruct the
driver's view of the front blind spot re󽗊ector, and there are no obstacles (such as the
interior rearview mirror or glass coating) in front of and around the camera lens in the
driver's cabin monitoring view.
The general selection of the installation area is shown in the diagram below:
Recommend installation area for the forward facing camera:

4.3 Installation of the main unit.
1. Park the vehicle on a level surface.
2. Clean the inside and outside of the target installation area on the windshield using
an alcohol swab. Ensure that there is no dirt or debris on the glass that could obstruct
the view of the road condition monitoring lens. Make sure the glass is dry.
3. Peel o󽗈 the 3M adhesive tape.
4. Align the device with the target installation area on the windshield, following the
direction indicated by the arrow on the bracket.
5. Press device 󽗉rmly against the windshield for 10 seconds, ensuring that there are no
air bubbles between the main unit and the glass.
4.4 Adjustment and Fixation of the device
After the device has been mounted on the bracket, adjust the front facing camera up
and and down to an appropriate position then tighten the two screws of the camera by
screwdriver:

16
When 󽗉x the cabin camera, ensure that the screen meets the following conditions:
a) The center of the cabin should be positioned in the middle of the screen.
b) The cabin screen should be horizontal.
c) The vehicle's steering wheel should be displayed in the lower left/right corner of
the screen.
The properly adjusted cabin monitoring camera rendering is shown below:
The MC403 supports maximum 4 cameras, please choose which type of the rest 2
cameras you required and which of the position you would like to install inside or
outside the vehicle.
*Note: Only when the device is securely connected to the vehicle, can the device be
powered on. If the device is fixed after power connection, it should be powered on
again before testing or use.

17
4.5 Power Connection, Signal Cable, and Cable Connection
Connect the power/ACC/GND to the vehicle's power supply line.
*Note: The power line should preferably be connected using "dedicated non-stripping
connectors" (no need for stripping, to avoid the risk of electric leakage) and wrapped
with insulating tape to prevent electric leakage/short circuit. If there are no special
non-stripping connectors available, stripping wires can also be used for the connection.
In this case, the connection process must comply with standard specifications. After
the connection is completed, wrap it with insulating tape to avoid electric leakage/
short circuit.
