1.Make sure the hardware and software of the VCI device is the latest version. If not, upgrade the VCI first.
确保VCI设备的硬件软件为最新版本，如不是，先进行VCI升级。
2.Before use, put the Rcfg file into the SD card. The Rcfg file is TXT file, as shown in the screenshot (0 corresponds to 6/14 of OBD,1 to 3/11 of OBD, and users can configure it according to the actual vehicle requirements);
在使用前将Rcfg文件放到SD卡中，RCfg文件为txt文件，内容如截图所示（0对应OBD的6/14,1对应OBD的3/11，用户可根据实际车型需求自行配置）； 3. Be sure to insert the SD card into the VCI device before connecting to vehicle OBD interface.
务必保证VCI设备在断电情况下先插入SD卡，再插入汽车OBD口；
4. When the red light of the VCI device flashes continuously ,it indicates that the recording is considered to have started.
VCI设备红色灯连续闪烁即认为已经开始记录。 5. Wait 3 minutes after the problem appears before unplugging the VCI device;

found after VCI device recording function is enabled (for example: A60_15T0001.JCL), please check whether the RCfg file exists on the SD card, and the content of the file is correct.
若开启VCI设备记录功能之后没有找到记录文件（例如：A60_15T0001.JCL），请检查一下SD卡是否存在RCfg文件，并且文件内容正确；
2. Do not connect the VCI device to the bluetooth when recording messages. If the VCI device is connected to the SD card via bluetooth during the recording process, the recording function of the SD card will be automatically disconnected and transferred to the diagnostic function, and the recording function of the SD card will not be automatically restored (if this happens, please reconnect VCI device and start recording messages again).
VCI设备记录报文的过程中不要连接蓝牙，若在SD卡记录过程中使用蓝牙连接VCI设备，则会自动断开SD卡记录功能，转为诊断功能，且不会自动恢复SD卡的记录功能（若发生该情况，请重新插拔VCI设备重新开始记录报文）；
3. The record file is in JCL format, which is a specific binary file. The user cannot open it directly, so he needs to contact JAC the technician for analysis.
记录文件是JCL格式，是特定的二进制文件，用户无法直接打开，需要联系技术人员进行转换、解析。
4. Since re-recording message will delete the existing SD message ,the SD card record should be copied to the computer for backup after completion of each SD card record. Otherwise, the JCL file will be emptied in the next record.
因为重新记录报文都会删除之前SD已存在的报文，每次SD卡记录完成之后均需要拷贝到电脑进行备份，否则下次记录时JCL文件将被清空。
