Please Noted:
When the star projection lamp is used for 2-3 hours, the internal temperature of the machine is too high, which will cause the color change of the disk under high temperature, but only the galaxy disk will not change color. Please change a film about 2-3 hours after use or let the machine rest for heat dissipation to avoid the color change of the disk due to high temperature
One discks should not be used continuously for more than 3 hours, otherwise it may be damaged because of the temperature rise.
