Hi-Fi Sound; Channel Caption (Station Identifier) - Hitachi VT-F494A Owner's Manual

Getting Started (Initial Setup)
indicator on the TV screen.
STEREO is the normal factory setting because it works for both stereo and mono
broadcasts. It is also necessary for recording a second audio program (SAP).
When you select MONO, sound is recorded as mono even when a channel broadcasts
in stereo.
Use the MONO setting when the stereo signal is not strong enough for quality reception
(for example, when there is signal drift of noise).

Hi-Fi Sound

Hi-Fi sound is the same quality as that of a compact disc player. Its dynamic range of
over 90dB will record either stereo or monaural broadcasts with the highest quality
possible. Linear sound, on the other hand, will record monaural sound using the same
format as a non hi-fi VCR. Stereo programs are recorded in hi-fi on both the left and
right channels and also recorded on the linear track as monaural.

Channel Caption (Station Identifier)

When your VCR is receiving a channel caption signal that is being transmitted by a local
broadcasting station together with a TV program, a station identifier is displayed on the
TV screen.
