NOTE: If the Universal LNB is selected, both 9750 and 10600 MHz are
supported at the same time, and therefore the 22 KHz tone setting
is not required.
E. LNB Power
Select LNB power ‘ On’ for internal and ‘ Off ’ for external.
F. 22 KHz
If you are using a 22 KHz tone switch box, make 22 KHz tone switch enable or disable
to select LNB or antenna.
G. 12V
Use it if the switch box is controlled by 12V DC.
H. DiSEqC 1.0
The PVR is designed to be DiSEqC 1.0 compatible. This allows multiple antennas to be
connected to the PVR at the same time. If you are using two or more fixed antennas or
LNBs, then it is recommended to use a DiSEqC 1.0 switch.
Select from 1 of DiSEqC to 4 of DiSEqC, M i n i A, M i n i B or D i s a b l e
according to the option or the configuration of DiSEqC switch box or antenna.
