Start at lowest channel?
Start at current channel?
Search up or search down?
Search TV first or DTV first?
No search if clock channel is already found?
It would be good to show clock channel on a SKIP display.
(Our setting structure)
Auto-Clock -- Auto (1)
-- Manual -- Analog channel (2-1)
-- Digital channel (2-2)
If you set "Auto-Clock--Auto", unit try to receive time signal from analog channel.
Unit search from lower set channel to upper until unit finds a time signal.
Once unit has received time signal, unit memories the channel and connect same channel next time.
If time signal is not contained in same channel, unit searches from lower channel until finding time signal again.
Analog signal contains TIME data suitable for your region.
Sometimes, broadcast station transfers other region TV program to his region (ex. LA station transfers NY TV program to LA residence) without exchange time signal.
In such case, unit receives NY time and memories it in the clock.
If you select "Auto-Clock -- Manual", you can select channel from analog and digital channels.
The receiving channel is fixed and unit does not attempt to find time signal channel even if time signal is not included in it.
If you select one of analog channel as time signal channel, unit receives time signal same as (1) but unit does not scan.
If you select one of digital channel, you also need to set your time zone.
Digital channel time signal contains GMT data (Greenwich Mean Time).
Unit combines GMT and time zone that you have set.
It means if the broadcast time data is trustable, digital auto clock is useful.
But our engineer doubts the reliability of the data.
1) Never use Auto-Clock -- Auto
2) Never select Auto-clock -- Manual -- Analog channel
3) If you do not mind unit sets incorrect time sometimes, you may choose "Auto-Clock -- Manual -- Digital channel".
4) If you are a nervous person for unit time, you had better turn off the auto-clock and adjust sometimes.
