The display of date and time from left to right reads as follows:  "yymm.dd  hh:mm:ss" 

(yy = year, mm = month, dd = day, hh = hour, mm = minutes, ss = seconds).  You can 

modify the displayed time and date in the usual way by using the Hand Controller's DEC 

buttons to change the current digit, and using the RA buttons to move from digit to digit.  

When you are at the far right digit of the display, pressing the RA+ button causes the new 

UTC date and time, to the second, to be entered into the RTC.

IMPORTANT:

  If you use the   Setup

 UTC Date/Time   menu item to change the date 

and/or time of Gemini 

s RTC immediately after a Cold Start, the new values are not used 

to set the initial pointing model until Gemini is powered off, powered back on, and Cold 

Started again.  This does not apply if you set the date and time when prompted during the 

Cold Start.

This menu item loads the information buffer and displays credits for those who 

participated significantly in Gemini 

s design and development.

Losmandy

Mountain Instr.

Executing this menu item allows you to do a CMOS reset, restoring all of Gemini 

s 

parameters to their default values.  Since the defaults are different for the Losmandy and 

Mountain Instruments GEM mounts, you must select one or the other.  For example, to 

restore Losmandy defaults, execute "Restore Defaults

Losmandy."

comfortable to prevent losing your dark adaptation.  The brighter settings can be used 

during the daytime.
