If for any reason your GPS can't pick up a signal you can manually enter the GPS coordinates.
Press ◄ or ► key to move the cursor and using ▲ or ▼ key to toggle between "W" and "E", "N"
and "S", using number key to change the numbers. It is always a good idea to do your home
work to get the GPS coordinates before traveling to a new observation site.
The site coordinates information can be found from internet, such as GPSVisualizer
(http://www.gpsvisualizer.com/geocode), by entering the city name or address. In case you only
find the site information in decimal format you can convert them into d:m:s format by multiplying
the decimal numbers by 60. For example, N47.53 can be changed to N47º31'48": 47.53º = 47º
+0.53º, 0.53º=0.53x60'=31.8', 0.8'=0.8x60"=48". Therefore, 47.53º=47º31'48" or 47d31m48s.
Same as N47º31.8': 31.8'=31'+0.8', 0.8'=0.8x60"=48".
Press ◄ or ► key, move the cursor to the bottom of the screen to set the time zone information
(add or subtract 60 minutes per time zone). Enter minutes "ahead of" or "behind" UT (universal
time).
•
New York City is 300 minutes "behind" UT
•
Los Angeles is 480 minutes "behind" UT
•
Rome is 60 minutes "ahead of" UT
•
Beijing is 480 minutes "ahead of" UT
•
Sydney is 600 minutes "ahead of" UT
All the time zones in North America are behind UT, as shown in the following table. So make
sure it shows "behind" instead of "ahead of" UT.
Time Zone
Hour behind UT
Enter Minutes
To adjust minutes, move the cursor to each digit and use the number keys to input number
directly. To change the "behind" or "ahead of" UT, move the cursor to "ahead of" and using ▲ or
▼ key to toggle between "behind" and "ahead of". When the number is correct, press ENTER
and go back to the previous screen.
