There is no user guide manual with (6) pages.

what you were referring to?

Thanks,

"Controlling TVs with the remote

You can control the sound level, input source,
and power switch of your Sony TV with the
supplied [DVD player] remote.

If your TV is listed in the table below,
set the appropriate manufacturer’s code.

When you replace the batteries of the remote,
set the appropriate code number again.
"

That implies the DVD remote stores the manufacturer
number of the TV set it's talking to over CEC.

https://en.wikipedia.org/wiki/Consum...ronics_Control

"Consumer Electronics Control (CEC) is a feature of HDMI
designed to allow users to command and control devices
connected through HDMI by using only one remote control.
"

"The bus is electrically identical to the AV.link protocol,
but CEC adds a detailed higher-level message protocol.

Single wire rather than two wires.

417 bit/s
"

That means it's about as slow as the very first modems.
And it uses one wire inn the HDMI cable, to pass
control messages along the cable.

For most people (who don't enjoy figuring stuff out),
the main advantage is the power button on one
remote, turns multiple hardware toys on and off
at the same time. So the DVD player and TV
go on and off as a "team". That's if you program
the remote with the appropriate code from the
table on page 6 of the PDF.

Make sure that's the correct PDF for your DVD player.
