DIRECTV R16-300 User Guide - Page 54

Other Information  If you are trying to operate a device other than the DIRECTV Plus DVR that you have programmed the remote to control, make sure you first slide the input switch to the corresponding device (DVD player, VCR, etc.). The indicator light for the component you're trying to control should light up when you press a valid key for that component. If it doesn't, make sure the input switch is clicked into the correct position. A remote control indicator light starts flashing. The batteries in the remote control are running low and should be replaced soon. (Note that when you replace the batteries, you may have to reprogram your remote to control other devices.) Fine-Tuning the Signal If you self-installed your satellite dish antenna, you may have already used Guided Setup to find the dish-pointing coordinates, acquire and fine-tune the signal and run a system test. If you need to run Guided Setup again, select Settings from the Menu, then select Guided Setup. Next, press SELECT on Satellite, then select Repeat Satellite Setup. Important If your TV is connected with just coaxial cables, you must tune to Channel 3 or 4, as set with the 3/4 switch on the back of your DIRECTV Plus DVR. 48
