Please download and install new firmware if the following 2 cases apply:

Check the system link:
1) Example: connect to HDMI v1.3 audio amp only. Source (provide 8 audio channel source) ----> 1x4 HDMI splitter ----> HDMI v1.3 8 audio channels amp only , the audio amp will provide 8 audio channels

2) Example: Connect to HDMI v1.3 audio amp and 2 channel audio TV Source (provide 8 audio channel source) -----> 1x4 HDMI splitter ----> HDMI v1.3 8 audio channels amp & 2 audio channels TV, the audio system will drop down to 2 channels.

In this case the 1x4 switch is only recognizing the 2 channel audio of the TV in the system link.

I have an UltraRun cable. Where do I plug in the power adapter?

Are Accell's HDMI cables compatible with the new HDMI specification Ver. 1.3?

The HDMI specification version 1.3 is fully backwards compatible with earlier versions of the HDMI specification. This means that the Accell HDMI cables and devices that are compliant to the HDMI 1.2 specification will work with an HDMI 1.3 compliant device. The first product to use the new HDMI 1.3 specification is the Sony Playstation 3. Accell's UltraRun HDMI cables, UltraAV cables and UltraAV 2-1 HDMI Switch and 1-2 Splitter are ideal for use with the PS3.

My cable does not seem to be working.

• Check the connection and cable. Are the connectors securely inserted into their receptacles? It's worth checking your connections again.
• Are there transparent dust caps on the ends of the cables? Some of our products come equipped with dust caps for protection. Please remove them before connecting your cable.
• Try another cable. This is easy for cables like USB cables or power cords that you can borrow from another device. If you find that the other cable doesn't fix the problem, you are likely experiencing a problem with your hardware device. Contact your component or peripheral manufacturer's support line for help.
• Are all the components powered on? Make sure that your device is plugged in and turned on.
• Have you installed the correct software to run your peripheral device? Many problems arise from improperly functioning of components or peripherals. Contact your component or peripheral manufacturer's support line for help.

The connector sleeve of my A/V cable is loose.

The metal sleeves on Accell UltraAudio and UltraVideo cables are designed to screw on the end of the cables connector. Try turning the metal sleeve clockwise to tighten the fit.

The cable doesn't seem to fit in the receptacle.

• First, make sure that you've oriented the connector properly to the receptacle. Often times, there is a "key" or a plastic notch that indicates the orientation of the connector.
• Next, check to make sure that there are no plastic end-caps on the connectors. Some of our products such as our DVI and fiber optic cables come with transparent protective dust caps.

My cable appears to be damaged.

If you've just purchase the cable, please check with your reseller about getting a replacement cable. Accell does not take responsibility for damages that are a result of normal wear, abuse, shipping damage, or failure to use the cable in accordance with the instructions.
