This kit is intended for installers with basic soldering skills. Each kit is tested before shipment to it is in working order. Therefore, some residual solder may remain on the circuit board. Customers who are concerned about this should refrain from ordering. This kit utilizes zero-force insertion technology to connect flexible flat cables (FFC). FFC connectors are fragile in structure and can be easily damaged if handled carelessly during operation. You need to be familiar with this technology. Installation Instructions: This item is from the later 5.3 version, with the main erboard flashed to firmware 3.1. If you cable has an attenuation resistor inside, then make sure JP2 is closed/shorted. If your cable does NOT have an attenuation resistor then make sure JP2 is open. These cables with attenuation resistors are still recommend on 5.3 and later.

Make sure you know how the work. Determine how to connect the GCDual to the analog port. Jumper pads on the QSB circuit board allow routing signals to different locations. You can access the documentation at the following URL to review jumper settings. This document also details the required steps for PAL and NTSC hosts using the CHROMA and pins.(Please contact customer service for documentation.) : Dissamble the , so the motherboard is free. *Leave the heatsink in place, unless you plan to replace thermal pads. Desolder the highlighted areas with desoldering braid. Install the original heatsink screw with the supplied #3-56 Nut into the hole closest to the digtal port.
