Operating Instructions
The SUNUV SUN7 offers multiple curing modes and smart features for optimal performance.
Timer Settings:
The lamp features four preset timer buttons for convenient operation:

- 30s: Standard curing time for many gel polishes.
- 60s: Longer curing time for thicker coats or specific gel types.
