2) Mandatory Boil & Mold (First Setup)

Bring clean water to a rolling boil in a small pot.
Lower the heat; using tongs, fully submerge the device.
Keep it in the hot water for 4 minutes (for sterilization and softening).
Remove with tongs; wait 10–15 s to avoid burns.
In front of a mirror: With the logo tip facing up, center the device and bite firmly and evenly for 5–10 s so the pads take your dental shape.
Remove and set in cold water for 30–60 s to lock the mold.
If the fit isn’t right, repeat the steps or use a spare pad.

Safety notes:

Do not use a microwave/dishwasher.
Avoid prolonged contact with the pot’s metal bottom; keep it floating/submerged.
If it feels too hot, wait a few seconds before molding.

3) Posture & Technique

Neutral head/neck, relaxed shoulders; device centered; no jaw jutting; smooth compressions with slow nasal breathing.
