Narrative:
After departing we leveled off at 14;000 ft and as airspeed increased above 230 KTS we experienced a landing gear unlocked indication followed by an hydraulic pressure on annunciator. The pilot flying immediately reduced the power and extended the speedbrakes to slow below gear extension speed. An immediate request was made to approach for a diversion to visit the cessna service center. Upon slowing below 230 KTS the associated gear unlock and hydraulic pressure on annunciators both extinguished. We refused any assistance from ATC and ground personnel upon landing and an uneventful approach and landing was made.
