Rega P25 Tonearm Lift

Here is my stupid question of the day. Hopefully somebody can help. I installed a Grado Sonata cartridge on my P25. Alignment and tracking force are set correctly. My problem is that the height of the cartridge doesn't allow it to clear the LP when using the tonearm lift lever. I have to manually pick the tonearm off the record when done listening. Does anybody know if the lift is adjustable-the manual makes no mention of it. Or-has somebody run into this with there own setup and perhaps developed a 'rig' for it? Any suggestions would be appreciated.
