About the SBC LI970
Most remote control systems have to be operated by pointing the remote control
directly towards a device. Any obstacle between the remote control and the device
disturbs the operating signal. But what if you like to place your devices inside a
closed cabinet, a closet or even in another room?
The SBC LI970 provides the solution to overcome obstacles like furniture or walls.
Your devices no longer have to be placed in line of sight but can be operated from
virtually any location. The SBC LI970 is a RF Extender that is used in combination
with the ProntoPro Remote Control. The RF Extender receives radio frequency
(RF) signals sent out by the ProntoPro and converts them into infrared (IR) signals.
These IR signals are then sent out to your TV, DVD, preamplifier and so on.

of sight (situation A).

Working Angle and Range of the IR blaster
Warning The IR signals sent out by the RF Extender always have to be able to reach the
receiving eyes of your devices. Make sure that the IR blaster (dark plastic window
on top of the RF Extender) is aimed at your devices.
To get optimal results, it is recommended to place the RF Extender horizontally
with the IR blaster facing up or down.

can be placed at a distance and higher than your devices. Make sure there are no
objects between the RF Extender and the receiving eyes of the devices.
