★Product Size: 2.4*2.4*1.1in ★Product Weight: 2.3oz ★Product Package Weight: 4.2oz ★Product Package Size: 3.5*1.6*3.5in ★Special Tips for Use: ★1.Expand the data line First, open the cover of the data cable box and remove the two ends of the data cable from the cable duct. Second, you need to hold the plugs on both ends of the data cable with your left and right hands, and pull them open to both sides simultaneously. Stop when you pull to the required length, and the data cable will be fixed at the position of your required length, keeping it stable. The data cable can be set in 5 different lengths. Note: Your hands must be pulled to both sides at the same time! Otherwise, the line will get stuck. ★2.Storage data cable When you want to retract the data cable after use, it is recommended that you lay the product flat on a table or other flat surface (you do not need to place it on the table after you are familiar with the use method), and then stretch the data cable To the maximum length (limit length of the data cable), then release both ends of the data cable with both hands at the same time, the data cable will automatically retract quickly. Finally, place the two ends of the data cable back into the grooves. (When you are skilled, you can hold both ends of the data cable with your hands and quickly retract them together to complete.) Note: When you want to store the data cable, you need to continue to pull the data cable to the limit of the data cable even if the data cable is in the maximum length position! Please repeat the above operation if the retraction is unsuccessful. Please don't worry!
