4. Inspection and Maintenance
The main electrical components of the USBCANFD interface card are semiconductor components. Although
it has a long life, it may also age quickly under inappropriate conditions. Periodic inspections should be carried
out to ensure that the required conditions are maintained. It is recommended to check at least once every 6
months a year. Under unfavorable environmental conditions, inspections should be carried out more frequently.
If you encounter a problem during the maintenance, see Table 4.1 to identify the fault cause. If the fault
persists, contact Guangzhou ZLG Electronics Co., Ltd.
