Okay January 1604

The port costs 3x the price of the product but good. Light hat Felt. We need to make it work, first open the battery box cover inside (fragile care or pre-broken, handle with care). Then remove the film cut-circuits the circuit, then press the small button to the discrete cap. I thought it was a support whose star had peeled off, but no. This is an on / off switch. The stars march from left to right. So if you are cautious, you can change the batteries one day and make it last cap.
