SCTV Clock Assembly Manual 1/24/22 31
Using Your Clock
Adjusting the display
The top left knob is Brightness. It should be adjusted so that the green display is visible but not overly
bright. The top right knob is Focus. It should be adjusted for sharp lines.
The lower left knob is Horizontal Position. It will center the display to the left or right. It also serves as
the left player paddle for Pong, and the block position control for Tetris. It must be recentered after
playing a game and switching back to clock mode.
The lower right knob is Vertical Position. It moves the display up and down on the screen. As with the
Horizontal Position control, it serves double duty for Pong and Tetris. It is the right player paddle for
Pong and the block rotation for Tetris.
The large knob at the bottom center is the Mode knob. It is used to select different clock or game
displays, and to adjust the time or locale settings.
Setting the time
The USB jack allows a GPS receiver to set the time automatically, although you have to set the time
zone and DST manually.
The setting mode is entered by pressing the big knob until it clicks. You may have to hold the clock
case, as the knob requires some force to press. You will see a menu with three lines, the top line
highlighted. Rotate the big knob to highlight Set Time and Date, then press the knob again. You will see
the time and date displayed, with the top Exit line highlighted.
Turning the knob will change which item is highlighted. It will cycle through hours, minutes, seconds,
century, year, month and day.
Pressing the knob will enable that item to be changed, which is indicated by blinking the item value.
Rotating the knob will change the value. Pressing the knob again will highlight the next item, allowing it
to be changed. Pressing the knob repeatedly will end up on the Exit line, which will exit the menu to the
main setting menu when the knob is pressed. Pressing the knob once more will exit the menu and go
back to time display mode.
Setting the locale
To set the clock’s locale, push the large mode knob to enter the main menu. Rotate the big knob to
highlight Set Locale, then press the knob again. You will see several options to set.
Zone sets the time zone used for GPS time. It has no effect unless the optional GPS receiver is used.
24 hour mode selects whether the hours are displayed as 0..23 or 1..12.
DST on/off selects whether the GPS time is adjusted ahead by an hour. This is not automatic, since the
code required to handle all cases is beyond the abilities of the creator of the clock. Feel free to write
your own code.
