SPV C600 Power Management

[Guest nigelwilsonuk]

Hi there, I have just got a SPV C600 and there is a strange setting in the power managment screen, under display timeout there is the usual 1 minute - Never, but under that there is a setting that just list 0-10, what is this for ??? On my mates C600 it says light sensor enable (on or off) ....why does mine just say 0-10 ??

Help !!?!?!?

Thanks,
