Set Local Time
Use the ◄ or ► key to move the cursor _ and use the number keys to change the numbers. Use the
▲ or ▼ button to toggle between “Y” and “N” for Daylight Saving Time, or “+” and “-“ for UTC (Coordinated
Universal Time) setting. Hold the arrow key to fast forward or rewind the cursor.
In order to make the hand controller reflect your correct local time, time zone information has to
be entered. Press the ◄ or ► key, move the cursor to the third line “UTC -300 Minute(s)” to set the time
zone information (add or subtract 60 minutes per time zone). For example:
Boston is “UTC -300 minutes”
Los Angeles is “UTC -480 minutes”
Rome is “UTC +60 minutes”
Beijing is “UTC +480 minutes”
Sydney is “UTC +600 minutes”
All the time zones in North America are “UTC –”, as shown in the following table, so ensure the
display shows “UTC -” instead of “UTC +” if in North or South America.
To adjust minutes, move the cursor to each digit and use the number keys to input the number
directly. Use ▲ or ▼ key to toggle between “+” and “-”. When the time information entered is correct, press
ENTER and go back to the previous screen. Note that fractional time zones can be entered.
Do not manually add or subtract an hour from displayed time to reflect Daylight Saving Time (DST).
Instead please select “Y” for DST when daylight saving time begins.
For other parts of the world you can find your “time zone” information from internet.
Set Observation Site Coordinate
The third and fourth lines display the longitude and latitude coordinates, respectively. The longitude
and latitude coordinates will be automatically updated when the GPS picks up satellite signals. “W/E”
means western/eastern hemisphere; “N/S” means northern/southern hemisphere; “d” means degree; “m”
means minute; and “s” means second.
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 your smart phone, GPS receiver or via the
internet. Site information in decimal format can be converted 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.
Select N/S Hemisphere
The northern/southern hemisphere will be determined by your latitude coordinate, with one
exception. If you are near the equator (within +/- 10°), you can choose your own N/S setting.
If the polar axis is aligned to the North Celestial Pole, then set the mount to Northern Hemisphere. If
the polar axis is pointing to the South Celestial Pole, set the mount to Southern Hemisphere. Press the ◄ or
► key to move the cursor and use the ▲ or ▼ key to toggle between “Northern Hemisphere” and “Southern
Hemisphere”.
