Technical Specification
B.3.4 LNB Power and Control
This section applies to M2/P8R/942[A] and all M2/PSR/9xx models.
The Alteia range of QPSK Satellite Receivers provides LNB power and
control signals through the active RF input connector. The 22 kHz tone is
turned ON and remains on when high-band is selected. LNB power and
controls are enabled through the Satellite Input Menu (#4) Pages, see
Annex C, Menus.
