how to lower the cpu speed to 111?

Hi, everybody. I appreciate every minute of your time and effort that you donate to the PSP and map this. Finally My psp-290 works on my Map this 0.499 with V3.03oe-c. Locked satellites in 3-5 min. but I dont know how to lower the cpu speed to 111 for increasing the reception. Of course I can change the cpu speed to 222 under map this menu. Thanks.

In 'GPS Info' Menu press cursor up or down.

Thank you so much, I didnt expect to have your answer so quick. I can lock the satellites in 1 min! you are fantastic. I love map this. Take your time on V0.5. We are looking forward to it.
