The power cord may become loose if the cash register is moved or its wall-mounted location is changed. Maintenance Fix to the wall Mounted to host screen Maintenance of the cash register 1The position of cash register should avoid place with direct sunlight, large temperature change and be far away from water source and dirt. 2Keep the cash register far away from strong electromagnetic field 3In region or stores where the power quality is poor, voltage-stabilized source should be equipped to provide power to cash register separately. Dont plug and pull the energized component and peripheral of the cash register at the energized state. Dont carry the machine or internal component at will. Pay attention to cleaning work of the cash register and prevent water, dirt and oil. When cleaning the cash register, dont use damp cloth or chemicals to wipe machine body such as gasoline and thinner, etc. When the cash register malfunctions, the power supply should be cut at once and stop use. Dont dismantle or repair without authorization. …
