1.3.2. Precautions
To ensure safe use, satisfactory performance and extended service life of the product,
please pay attention to the following when installing and operating the device:
1) During the installation and operation of the device, make sure to observe all criteria for
electronic products as well as requirements for vehicles and other connection devices;
2) Power supply and grounding:
a) The direct input range of the power supply of the device should be DC 8V to 36V,
avoid reverse connection or short circuit of output. Please pay attention to the
power supply capacity of the power cable.
b) Even if the device is turned off, there’s still electricity left inside it, please prevent

Http://www.ifarsys.com Mobile DVR Manual V6.0
8
short circuit. Before connecting to other external devices, please cut the
connection between the device and the power supply;
c) The output voltage of the device is 12V, only used for power supply of the camera,
please do not enclose any device that are not allowed to be used on the device;
d) The sensor input mode of the device is leveling, if the external voltage is less than
2V, it is regarded to be low level, and the voltage between 5V~30V is regarded to
be high level, and the voltage over 30V will cause abnormal data collected by the
device or damage of the device. The voltage higher than 2V and lower than 5V is
illegal.
e) Correctly connect the earth wire of the device to the earth wire of the vehicle to
constitute the circuit;
f) If the device is to be laid aside for a long time, it is better to completely cut the
power supply to extend the service life;
3) Humidity requirements:
a) The device should be installed in dry environment, avoiding humid, dripping and
spraying of water. Do not install the device at sunken locations with the possibility
of water accumulation or wet locations subject to liquid dripping;
b) Do not touch the device by wet hand or touch the device while standing in water
or other water sources, which may cause electric shock;
4) Installation locations:
a) To extend the service life of the device, try to install the device at locations on the
vehicle subject to slight vibration.
b) The device shall be installed in ventilating parts of the vehicle: when installed on
a level plane, the device shall be kept 6 inches (15cm) away from other objects to
facilitate ventilation and cooling; do not install the device in an enclosed space
(the trunk, for instance).
c) External cables of the device should be provide with sufficient spacing and
flame-retardant housing to prevent the cable from bending or abrasion due to
vibration and thus cause leakage of electricity;
d) Keep the device from heat source of the vehicle or sundries, it is strictly
prohibited to place anything on the device.
e) The device can only be installed horizontally or vertically sideways (please
consult the manufacturer if you need to install it along another direction),
installation at any other angle may damage the device and is strictly prohibited.
5) Device safety:
a) Prevent the driver or passenger from intervening or damaging parts, cameras,
cables and other accessories of the device, keep the device away from other
restricted vehicle parts;
b) Starting the vehicle while installing components, cameras, cables and other
accessories of the device may cause damage of the device, keep the vehicle still
during the installation and prevent it from dropping.

2.3. Definitions of External Cables
2.3.1. Power Cable
The figure below shows the power cable, and the red wire and the black wire are directly
connected to the battery jar of the vehicle. The red wire is connected to the positive pole,
and the black to the negative pole. The yellow wire is connected to the ignition wire when
the on/off mode is set to ignition mode. The device will be automatically turned on once the
vehicle key switch is turned on and automatically turned off when the vehicle key switch is
turned off. The yellow wire is connected to the position for the vehicle key to turn on all
dashboard lights (the one before the position to start the motor).
Note: 1) Before connection, confirm the voltage of the battery jar between 12UUVUU —24UUVU U, or
the device may be burnt;

Http://www.ifarsys.com Mobile DVR Manual V6.0
12
2) After the connection, pay attention to the insulation between power cables to prevent
short circuit of the power supply that may burn the battery jar.
3) The yellow wire must be connected to the ignition wire, otherwise, the device will not
support ignition mode.
4) Note: the mobile device must be directly connected to the positive and negative poles of
the battery jar without any earth, which may generate negative pulse and disturb normal
operation of the device. Power cables for the positive and negative poles must have the
diameter of above Φ1.5.
