RCA 27F500T - Manual (Page 33)

Multi-channel Sound (MTS) broadcasts
enhance TV viewing by bringing you programs
with high fidelity stereo sound. MTS also
provides an extra channel called the Second
Audio Program (SAP), which broadcasters can
use to transmit a second language or for other
purposes.
Press MTS on the remote control to
select
STEREO, MONO, or SAP. All the
options will be available only when the
current TV channel is broadcasting that
option. Channels will not always carry
programs that have all the MTS options.
If STEREO appears on the screen when
you select a channel, stereo broadcasting
is available with the current TV program.
You can hear sound from the left and
right speakers of the TV.
If the broadcast is not strong or clear,
stereo sound is not available. Press the
MTS button to change to MONO. This
should eliminate the noise.
If MONO appears on the screen when
you choose a channel, Stereo is not
available.
If SAP appears when you select a
channel, Second Audio Program
broadcasting is available for the current
TV program.
Press the MTS button to choose SAP and
you may hear the program in a different
language or some other audio.
