PART XII : USING A SYNSCAN GPS MODULE
12.1 Initialization of the Hand Controller with a SynScan GPS Module
12.2 Checking GPS Information
3. The hand controller will then ask the user whether to use the Daylight Saving Time. Use
the scroll keys to select between “YES” and “NO” and press the ENTER key to conrm and
proceed.
4. The screen will now display “GPS xing…”. It means that the GPS module is trying to x to
the GPS satellites.
5. After the SynScan GPS module xes to the satellites, the SynScan hand controller will
continue the initialization process.
1. Plug the SynScan GPS module into the multi-purpose port (the 6 pins RJ-12 port) located
at the bottom center of the SynScan hand controller. Place the GPS module on a horizontal
surface.
2. Access the menu “Utility Func. \ GPS” in the menu and press the ENTER key.
3. The screen will now display “GPS xing…”. It means that the GPS module is trying to x to
the GPS satellites.
4. After the SynScan GPS module xes to the satellites, the screen will display “GPS Infor-
mation:”. Use scroll keys to browse through the following information. Press the ESC key
to exit.
• Use the left and right direction keys to move the cursor on the screen.
• Use the scroll keys to change or switch the sign for the time zone. Use “+” for the time
zones in the Eastern Hemisphere, use “-” for the time zones in the Western Hemi-
sphere.
• Use the numeric keys to ll the time zone value in ±hh:mm format.
• Press ENTER to conrm and proceed.
• M.O.V: Local magnetic declination

The initialization process of the SynScan hand controller with a SynScan GPS plug-in differs
from a regular one.
1. Plug the SynScan GPS module into the multi-purpose port (the 6 pins RJ-12 port) located
at the bottom center of the SynScan hand controller. Place the GPS module on a horizontal
surface and turn on the power of the mount.
2. If the SynScan hand controller detects the connection of a GPS module, it will ask for the
local time zone:
Users may purchase a SynScan GPS module to acquire accurate local geographical coordi-
nates and local time; it will help improve the accuracy of the mount alignment and the polar
alignment.
