5. Installation
5.1. SIM card
5.2. Sensor calibration
This procedure is important for proper “harsh behavior” detection.
1. Locate OBDII interface around steering wheel, tracker will make a sound of “bi” when plug in.
2. Please do not start the car at the beginning and keep still as possible
3. Wait about 20 seconds.
4. Tracker will make sound of “bi” 3 times which indicating “static calibration” finished.
Note: For each external power cycle tracker will restart calibration procedure.
Step1:
Metal part of SIM card facing down.
Step2:
Insert and push SIM card to the button of SIM
holder to lock it firmly.
