Need assistance installing an RF Tuner module (IMP-1200) into a Panasonic TH-42PD50U Display. I understand that there is some configuration needed. Please help !

Unplug power to the monitor before you attempt to install the tuner module and the Imp-1200 must be physically installed in slots 2 and 3 on the monitor.
Once card is installed, power on the monitor and enter the setup menu. highlight the OSD option then press and hold the surround button on the remote. This will enter a set of new options go to the digital slot option on page 3 and select slot 2. You should be done.
