What remote control code does the Onkyo TX-SR304 use?

I want to program ComCast's 3 in 1 universal remote to control my Onkyo TX-SR304 receiver in the "AUX" position. ComCast's instructions have me use codes 30135 or 30842. The 1st one will turn the unit on...the second code will turn the unit off, neither will control volume. There must be a code that's out there that will allow ComCast's universal remote to completely control a SR304.

    Same exact problem.

    The codes advised by Comcast fail to control the Onkyo Amp TX-SR304: code 30135 will switch it on, but will not switch it off, same, as far as I can tell with code 30482

    Same problem, except code 30135 turns the SR304 on AND controls the volume, while code 30842 only turns it off. Called Comcast: they said that Onkyo corp gives them the codes to use. Called Onkyo: they said they only have codes for their own remotes, and the codes Comcast uses were from them. Unlikely, because of the hundreds of codes needed for all sorts of devices. Maybe Comcast gets an IR pulse code sequence from the mfgrs, and figures out the codes for their remotes from that.

From: http://www.comcast.com/remotes/universal.html - only worked for me when I had AUX setup with 30135

Unlocking Volume Control For A Single Device (Individual Volume Unlock):

  1. Press a desired mode key where you want volume to be unlocked (e.g., AUX) and controlled within its own mode.
  2. Press and hold SETUP until the selected mode key blinks twice, then release SETUP.
  3. Enter 9- 9- 3 and then press VOL- once. The mode key will blink four times confirming unlock.
    If desired, repeat steps I to 3 (of this section) for each device that you want volume to be unlocked.
Now, after you select a device that has volume unlocked (e.g., AUX), pressing VOL , VOL-, or MUTE will control the device's volume only in its own mode.

How to program remote control?

Your Onkyo TX-SR304 receivers remote (RC-645S) is not capable of controlling devices by other manufacturers. It controls only Onkyo devices.
Other Onkyo remotes do have universal remote functionality and you can download Onkyo remote codes here.

I hope that helps.

Need codes for universal remote

Not sure if this helps, but I just called Onkyo with a request for codes for the SR304. They said the only codes they have are for THEIR remote. Maybe they will work with yours. Here they are:
0276 0476 0810 1187 1376.
I tried these in the Comcast remote (adding a 3 in front of the numbers) but that didn't work. Still trying to get my Comcast remote to program the Onkyo SR304 adequately, since their published codes only partially work.

Cant find universal remote code for the onkyo tx-sr605

Your onkyo receiver and remote controller only decodes 4 digit codes so what you have to do is to call the manufacturer of the remote controller it self and ask for the hexa decimal codes for their remote. They should provide it to you coz they're the ones responsible on doing that.
