Dear Sir,

The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

(2) BS The BS is supplied the power by AC line. While the BS is the stand-by, the BS is always a wake state. While the BS monitors the current channel, the BS monitors also the other channel at the same time Because if the current channel can not use by some interference, the system needs the clear channel information as a part of system parameter for a channel hop. If the BS can not receive the A-Frame of Heart-beat from the HS, it become �link error�, and the system become error recovery mode.
