First you need to know that the guiter hero 3 comes with a wireless dongle on it. It is most times attached to the bottom of the guiter hero 3. Slide it off the guiter and connect it to your playstation 3, a light will flash on the dongle. Then you press the PS button on the guiter 2 times and it will connect.
This could take a while for you to get it but most times it takes two taps on the button.
There are other ways to try such as:
- If you play Guitar Hero III on PlayStation 3, you'll get a wireless controller, but it doesn't work seamlessly with PS3's built-in Bluetooth. You'll have to plug a dongle into the USB port on your console.
- if you're going to have a dongle hanging there, you may as well make it pretty. Guitar Hero's is shaped like a guitar pick.
- The dongles have sync buttons on them, so you can just tap the button on your controller, then on the dongle to sync them up - perfect if you have more than one controller.
Here is another way to connect you guiter hero 3 to your playstation 3.
Do the following to connect and sync your guitar to the Playstation 3.
Connect the wireless dongle to one of the USB ports on the front of the system.
If there is a solid red light on the dongle check your guitar for a red indicator light. If there is a light you are finished.
If there is no light or the light is flashing press in the small button on the front of the dongle
A red light will flash on the dongle and the position indicator lights will flash above the guitar's strum bar
Press in the PS button on the guitar, the red lights above the strum bar will stop flashing and only one red light will remain illuminated. It may take several seconds after hitting the PS button for the flashing to stop. If it is taking longer than a few seconds and the lights are still flashing press the PS button again, you may need to hit the PS button several times.
If all of the lights flash and then go out do the following. Move or turn off anything near the PS3 that uses a wireless transmitter (this includes cordless phones and other non PS3 wireless controllers). If your PS3 is inside an entertainment center please remove it and try to sync the guitar again. Large metal objects near the wireless transmitter can also interfere with the signal. You should also vary your distance to the console, if you are far away come a little closer, if you are close move back. We have seen people being to close in particular cause issues during the syncing process.
If any of this does not work, then you will have to take it back to the dealer that supplied it to you. It should still be under warranty.
All the best.
