Wireless

[vg3]

How can i disable the wireless function of the PSP? (Like you can do, for example, with a wireless modem-router).
I'm asking this because i believe that the electromagnetical radiation you get with wireless technologies, like Wifi, is dangerous for humans, especially children.
My PSP has a switch, called WLAN On/Off, at the left side and I think that this can turn off the WiFi, but i don't know if it must be upwards as the arrow on it points or downwards.
What happens when you select from the menu: Settings > Power Save Settings > WLAN Power Save: On ?
