Questions on range/targeting of Telescan psionic power

[Deathwindfr]

Dear all,

Reading the Telescan psionic power (Psionic Powers p67) leaves me with some unanswered questions on range and targeting :

First of all, it says "For all power levels, success gives you a “lock” on the subject, allowing you to use further telepathic abilities on him at
no penalty." => Do I understand well that this means if another telepathic ability is used on the target, there are absolutely zero range penalties?

Second of all, the Omniscan technique says that the power "can scan for any minds nearby". What does nearby mean? Is Omniscan limited in range compared to the base power? Or does it use the same range penalties according to level?

Thanks in advance for your help.
