With this setting, you can correct this by delaying the audio signals. You can set it from 0 to 100 milliseconds (ms) in 20 millisecond steps.
Controlling Other Components You can use the AV receiver’s remote controller (RC-681M) to control your other AV components, including those made by other manufacturers. This section explains how to enter the necessary remote control code for the component that you want to control (e.g., DVD player, TV, or VCR). 1 Look up the appropriate remote control code in the separate Remote Control Codes list. The codes are organized by category (e.g., DVD player, TV, etc.).
Controlling Other Components—Continued Remote Control Codes for Onkyo Components Connected via Onkyo components that are connected via are controlled by pointing the remote controller at the AV receiver, not the component. This allows you to control components that are out of view, in a rack, for example. Resetting REMOTE MODE Buttons You can reset a REMOTE MODE button to its default remote control code.
Controlling Other Components—Continued To control another component, point the remote controller at it and use the buttons explained below. (You must select the appropriate remote control mode first.) With some AV components, certain buttons may not work as expected, and some may not work at all.
Troubleshooting If you have any trouble using the AV receiver, look for a solution in this section. If you can’t resolve the issue yourself, try resetting the AV receiver before contacting your Onkyo dealer. To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [STANDBY/ON] button. “Clear” will appear on the display and the AV receiver will enter Standby mode.
