After the phone is installed, follow the following steps to achieve a more comfortable effect:

1. Loosen the headband above your head, or turn it up first.

2. Then turn the connecting ring of the transverse headband to make the transverse headband lower in the back of the head and adjust to the position that there is no obvious backward pressure on the face.

3. Retract the headband to lift the fuselage without crushing the nose.

Note:Be sure to first adjust the transverse headband at the back of the head down, and then adjust the headband on the top of the head.

If the headband is too short, it will slide up and become unstable.

If you don’t care about the bridge of the nose, you can remove the bridge of the soft glue.
