Sony SLV-N51 - Manual (Page 20)

20 Setting the clock
Notes
• The clock cannot be set automatically if you don’t receive a channel that carries a time signal
in your area. If so, set the clock manually (see page 21).
• If there are only a few channels in your area that carry time signals, setting the clock
automatically may take up to about 20 minutes. If nothing happens even after you wait about
20 minutes, set the clock manually.
• If you use Hookup 3, make sure you leave the cable box on.
