Manual for TV feature, Phillips Magnavox TS2746 C221?
 

Our office was supplied with this model TV for a dedicated purpose and
we would like to keep it this way. Our specialist has uncovered the
possibility of entering a security password to lock, we presume, to
lock down our settings. Is anyone familiar with this feature on
Phillips Magnavox TV, or does someone have a manual to quote
instructions to us?
