Universal Remote Control R7 - LED Indicators and Battery Installation; LED Lights for Programming Status; Battery Installation Guide

LED Lights
To assist you in programming the R7 for your components, there is
an LED light under each one of the 7 component buttons located at
the top of the remote. The LED light glows red when you are
programming a particular component. This is a simple signal that lets
you know you are in the correct programming mode.
Battery Installation
Before we start, insert the two AA batteries that are included in the
package into the battery compartment located in the back of your
remote. Just press the tab and lift off the cover. Please be sure to
insert the batteries correctly as you see in the diagram. Remember,
there is a positive and negative end to each battery and you can tell
using + (positive) and - (negative) symbols. Once the batteries are
correctly installed, replace the cover.
