Connecting an External IR
Receiver
If infrared signals from the remote control cannot reach the display due to excessive
distance or obstructions such as walls or cabinet doors, you can connect an external IR
repeater system to the IR INPUT on the Crystal Series LCD to extend the range of the
remote control. See
Figure 3-8.
