4. Wiring precautions
Power supply, ACC, relay (4-PIN)
(1) The standard power supply of the equipment is 9V-58V DC. Please use the factory supplied power cord, the red
wire is the positive wire, and the black wire is the negative wire. When connecting the negative wire, please ground it
separately, and do not connect it to other ground wires;
(2) ACC wire (green) is used to connect to the vehicle ACC switch. Be sure to connect the ACC wire, because the
vehicle tracker will decide whether to enter the security status depending on the ACC switch status; if the ACC wire is
not connected, the vehicle will be kept in the security or sleep status. Under the status of security or sleep, if vehicle
vibration occurs, the vibration alarm will be triggered. If anti-theft alarm function is not required, you can connect the
ACC wire with the positive wire in parallel to maintain high electrical level.
5. Description of special functions
(1) Security function
If the ACC wire is connected to the ACC switch, this equipment will start the security function automatically in five
minutes after the vehicle engine is turned off. If vehicle vibration occurs within one minute, the equipment will enter
the security status with 1 minute delay, and will enter the security status unless no vehicle vibration occurs.
(2) Sleep mode
After entering the security status, if no vehicle vibration occurs within 20 minutes, this equipment enters the sleep
mode. In the sleep mode, this equipment neither locates nor uploads data, but can send/receive messages and
make/answer calls, so as to achieve maximum energy saving.
(3) Vibration alarm
Under the security status (including the sleep status), if vehicle vibration occurs, this equipment immediately
disconnects the relay and dials the mobile phone number of the vehicle owner to give an alarm; meanwhile, it wakes
up the GPS positioning, and uploads the alarm and location data to the service platform.

Wire cutting alarm
Under the security status, when the main power line of the vehicle tracker is disconnected, the vehicle tracker will
send the wire cutting alarm message to the mobile phone number preset to receive the SOS message and uses the
inner backup battery instead. The backup battery can work 7-10 hours. If the positive wire and negative wire of
equipment are connected together after power line had been cut, the equipment still works normally.
