Sony RM-VL900 Operating Instructions (primary manual) - Page 31

2 While holding POWER pressed, press the desired Component Select button. When you first press POWER, only the Component Select buttons that have already been set with the Power-On command light up. These buttons turn off when you press another Component button. Example: If the Power-On command has been programmed on the VCR and CD buttons, these buttons light up when you first press POWER. To clear the Power-On command Repeat the same procedure by pressing the Component Select button that lights up when you press POWER. Notes • If the component code of a non-Sony brand has been set on a Component Select button, you cannot program the Power-On function on it. The selected Component button flashes twice, and the Commander returns to its state in Step 1. • Even if you have programmed a signal by the Learning function (page 15) or the System Control function (page 27) on a Component Select button, you can program the PowerOn function on that button but it cannot be used. If you clear a "learned" signal or the System Control function on the button, you can use the Power-On function. • You can program a signal by the Learning function (page 15) or the System Control function (page 27) on the Component Select button on which the Power-On function has been programmed. In this case, the Power-On function is overwritten and cannot be used. If you clear the "learned" signal or the System Control function on the button, the Power-On function is resumed and you can use it again. If you have programmed both a signal by Learning and the System Control function on the button, the "learned" signal overwrites the System Control function. 31
