Note:
  Remember that the UTC date at certain times of the day may be one day ahead 
of or behind your local date. 
2.4.2.1.2  Setting your Mount Type/Parameters 
The Gemini system supports several different mounts, and needs to know which one you 
are using.   Gemini will display the currently selected Mount Type.  If you choose to 
change this item, use the DEC buttons to scroll through the mount types available.  When 
your mount is displayed, press the RA+ button to select it.  Gemini will then return to the 
startup process and allow you to change the next item. 
2.4.2.1.3  Setting Your Location 
In order to accurately position your mount, Gemini needs to know your position on the 
Earth in addition to the current date and time.  If you had a GPS connected during power 
on, Gemini read this data and you can skip the next two steps.  The GPS receiver can also 
be read later using the menu item   Setup
Geogr. Location
Query GPS Rec.   
To set your geographic location manually during startup, press any direction button on 
the Hand Controller when it displays either the Longitude or Latitude you wish to 
change.   
At the Longitude display, use the Hand Controller buttons to enter your Longitude as 
previously noted.  The longitude is counted from Greenwich, England; eastern longitudes 
are designated by  
E 
, and western longitudes (including the American continent) by  
W 
.   
After you have entered the last digit, press the RA+ button again to set the longitude. 
   
The display next shows   Latitude.    Press any direction button to initiate setting your 
Latitude.  Enter your Latitude using the RA and Dec. buttons to change digits as you did 
with Longitude.  Northern latitudes are denoted by the   +   sign, while the       sign is used 
for southern latitudes.  After you have entered the last digit, press RA+ again to complete 
the startup procedure. 
2.4.2.2  Completing Startup 
After the system has completed its startup tasks, it will display the UTC Date/Time, 
Mount Type, and geographic location.  It will then go into Menu Mode and display the 
  Align Telescope   menu item.   
Since the date and time you enter on the Gemini will be UTC, you need to set your time 
zone for correct conversion to your local time.  If the display has gone blank, you will 
first need to get into Menu Mode by pressing the MENU button.  Use the DEC buttons to 
scroll through the menu choices until you get to "Setup" and then press the RA+ button.  
You are now in the Setup submenu.  Use the DEC buttons to scroll through the menu 
choices until you come to   UTC Date/Time   and press the RA+ button to select it.    
Such navigation sequences will be abbreviated in this manual by using the names of the 
submenu items separated by a right arrow  
   symbol.  Thus, the menu item you just 
chose would be depicted   Setup
UTC Date/Time.
