There is abnormal noise: check whether the tool is damaged; check whether there is too much shredded paper; check whether the belt is loose. Attendance machine maintenance Unable to verify: choose better quality fingerprints when registering, try to make the area where the fingers touch the fingerprint collection head as large as possible, and register a few more backup fingers. Repeatedly pressing your fingers: Use self-adhesive tape to stick the dirt on the surface of the collecting head. If the motherboard chip and other accessories are broken, you need to contact the supplier.

High resolution cannot zoom: Adjust the resolution of the external device connected to the projector. Conference tablet Automatic shutdown: check whether the power supply is stable; check whether the timer shutdown or sleep function is turned on; check the channel where the input source is located. Abnormal touch function: check whether the touch pen or finger touches the screen vertically at 90 degrees; check whether other objects touch the screen, such as small notes, sleeves, etc.; check whether the external touch line is connected correctly. Conference Camera Repair No image: Troubleshoot the power supply, plug the power cord firmly. Uncontrolled: Replace the remote control battery, adjust the use distance. Loss of image: Check if the power cord plug is loose, replace the video cable. Conference audio equipment No sound: Check that all equipment is turned on; volume controls are adjusted; check that all cables are connected correctly. Loud hum: If necessary, add an audio transformer for isolation; unplug the connection signal line between the two systems from one system. There is interfering noise: All audio cables should be well-shielded audio cables, and the length should not be too long. Adding RF filters can suppress RF signals.
