Special Modes

• Away Mode
  Completely disables the device — no heating, lighting, or fragrance. Ideal for vacations, long absences, or when the device should not operate under any condition.

• Boost Mode
  Temporarily activates maximum heating and vaporization from the active slot for a short burst of fragrance (default: 30 minutes). Automatically returns to the previously active profile when the time expires.

  Note: For best experience, ensure both fragrance vials are filled. Profiles are designed to alternate between slots, so Cury will auto-switch between vials.
