902 problem 912 and micro sdhc

hello,

i put a microsdhc in the pocketbook 912, the computer can see the card, but how do I get it out again?

I don't dare to put it further in. In most devices it needs to be put in far enough and then it will pop out again. is this here the same case. i doesn't feel so. it's already too far in the inner realms of pocketbook 912.
