FT817nd xtal osc pins...which are output?

[VK3LU]

My ft817nd is a tad off frequency at 144mHz, at least 100Hz.
Now, that's not much on ssb but on WSPR it's a lot, half the bandwidth actually. Therefore I need to check the frequency of the 22.625 mHz osc in the little beast.
Does anyone know the pinout of the osc unit so that I can measure the freq.?

Thanks in anticipation
