Notes

• Make sure you hold the button on the board to bring up the remote programming menu BEFORE assembling your Panasonic Q (Save the settings in the menu after programming the remote)
• Cut the pin headers with a flush cutter before re-assembly, otherwise your disk assembly won't fit
• The cost with assembly from PCBWay should be around 78 USD
• HDMI output is for GC mode only
• Enhanced DVI needs to be turned on in the GCVideo settings for audio output
