STEP 10. Setup Hand Controller
The CEM25 is equipped with a GPS receiver, which will
receive the time, longitude and latitude information from
satellites after the link is established. However, there are still
some parameters need to be entered to reflect your location,
such as time zone info and daylight saving time. The
information will be stored inside the hand controller memory
along with longitude and latitude coordinates until they need to
be changed.
A clear sky and open space outside is needed for the
GPS to establish its link with the satellites. The GPS is
installed on top of the R.A. motor control board. If it has
difficulty to receive the GPS signal with the telescope installed,
you may turn the mount head 90º to the side of the mount to
clear the space on top of the main board.
Do not leave the
hand controller on GPS Status submenu waiting for GPS ON tuning into GPS OK.
To set up the controller, turn the mount power ON. Press

Set Local Time
The time will be updated automatically when the GPS receiver has established its link with the GPS
satellites. In the event that the GPS module is unable to establish a link to the satellites, local time can be
entered manually. 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”
