 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 +”.

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 one 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).
Only select “Y” after DST begins.
For other parts of the world you can find your “time zone” information from internet.
Set Observation Site Coordinates
The fifth and sixth lines display the longitude and latitude coordinates, respectively. The longitude and
latitude coordinates will be automatically updated when the GPS picks up a satellite signal. “W/E”
means Western/Eastern Hemisphere; “N/S” means Northern/Southern Hemisphere; “d” means degree;
“m” means minute; and “s” means second.
If, for any reason, your GPS does not pick up the satellite signal, you can manually enter your longitude
and latitude coordinates. Press the ◄ or ► key to move the cursor, use the ▲ or ▼ key to toggle
between “W” and “E”, and “N” and “S”, and use the number keys to change the numbers. It is always a
good idea to do your homework and get longitude and latitude 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
your 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”.
The time and site information will be stored inside the hand controller’s memory chip. If you are not
traveling to another observation site, they do not need to be changed.
Check the Hand Controller Battery
The hand controller has a real time clock (RTC) which should display the correct time every time the
mount is turned on. If the time is incorrect, please check the battery inside the hand controller and
replace it if required.
STEP 10. Set the Zero Position
Zero Position is the mount starting reference point which ensures the GOTO performance. Press
MENU => “Zero Position” => “Search Zero Position” to let the mount search the Zero Position.
Follow the instruction on hand controller display to adjust the Zero Position if RA or DEC is not aligned.
Or press MENU => “Zero Position” => “Set Zero Position”, to manually set the mount to Zero
