MAIN MENU FUNCTIONS
Brightness of the display screen
Use the <PREV and NEXT> buttons to adjust the brightness of the display to a bright or dim setting.
Note: Even when the Keypad is set to the bright setting, it will be difcult to
see during daylight hours. You will need to shield it with your hands. This is an
unfortunate drawback of the vacuum-uorescent screen. We originally chose this
display because of its excellent performance in cold weather down to -40º F (-40º C,
yes, the number is the same). Alternative displays scroll very slowly at temperatures
below freezing and would not work well at all in extreme temperatures. Since many
of our customers (and ourselves) observe during the cold Midwestern winter months,
we opted for performance.
Directional buttons
The N-S-E-W buttons are active at this point.

Time/LST
This display screen will show your local time, date, LST (local sidereal time, also
known as the zenith hour) and GMT (Greenwich Mean Time, also known as UST
– Universal Standard Time). If you have not gone through the startup routine, only
the local time and date will display. It cannot calculate LST and GMT until you enter
your location (unless Auto-start is set to “yes”). Press and hold MENU button a few
seconds to exit screen. In addition, the current selected location will appear in the
lower right corner. For example, LOC=1 indicates that location 1 is currently selected.
You will notice that the display will appear to skip a second once in a while. This happens because the display does not
update exactly in sync with the clock. As a result, it gets slightly behind and has to skip a second to catch up. This is not a
problem.
This is a display screen only. You must go into the Location and Time menu to change the data, time and location.
Slew rate (S:)
Press “5” on your Keypad to change slew rate: 1200x, 900x, or 600x. Note that the selection changes (toggles) each time
you press the button. We recommend that you use slower rates in cold weather.
Button rate (B:)
Press “6” on your Keypad to change the button rate: 0.25x, 0.5x, 1x, 12x, 64x, 600x, or 1200x. This determines the rate
that the mount will move when the N-S-E-W directional buttons are pushed. The selection changes each time you press
the button. This rate can also be changed on a display screen accessed by the “±” button.
