Step 1- Turn On All Your Devices - Logitech 915-000085 - Harmony 510 Advanced Universal Remote Control User Manual

Option 3 — Select the input from an on-screen
menu
In this case, your device uses an on-screen menu from
which you can select the input you want.
When you press the source button, the menu
appears on your TV screen. Then, you use another
button on the remote to choose the input you want,
and then a third button to select the input.
For example, you press the source button to display
the on-screen menu, the arrow keys to select an
input, and then the OK button enter your selection.
Option 4 — Select the source from a list
In this case, your device has a list of inputs and you
can use the buttons on the remote to select the
input you want from the list.
After you press the source button, you have to press
another button on the remote that selects the input
you want.
In this option, there's no menu from which to choose
(Option 3) and you don't have to cycle through all
inputs to get to the one you want (Option 1).
Step 1— Turn on all your devices
To determine which devices are using which inputs, Logitech recommends you start by turning
on all the devices in your entertainment system.
If possible, you should even start something playing in your DVD player, CD player, VCR, etc.
By having all your devices on, it's easier to see how they're connected.
It's also handy to have some paper and a pen so you can note which devices are connected to
which inputs.
