Installing the Remote Control Batteries
Before the remote control can be used, the two supplied batteries
need to be installed. First, unsnap the battery cover from the back
of the remote control. Install each fresh battery as shown, making
sure that the + and – on each battery line up with the marks in the
battery compartment. Next, snap the cover back onto the remote
control.
Refer to “Programming Your Remote Control” in Chapter 8 for
setting the codes to control the devices in your entertainment
system.
