Turn off the power and 't live operation when installing or disassembing2. The reader must be installed on wooden, concrete or brick wall, or placed on the table. It may not have a area of iron and steel within a radius of around 10 centimeters3. Different cards has affect the distance of reader4. If the distance of reader between two machines Less than 0., will interfere with each other. In other words, the best distance between the reader is at 0.3 above.5. If the card still in the sensing area, thereader without any prompts, and also 't send data.6. Access Control Reader 't data and information, 't increase the card, password and fingerprint . It's a tool for unlocking that just expanding into the card or password , you need to rely on the access controller, attendance card machines, or multi-door controllers.Only the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
