1.1Set Up

By default, the mount works in Alt-az mode. Turn on the power button located on the mount. You will see the iOptron logo screen. Then you will see the zero position screen:

TR.A.	1h36m 2s
TDEC	90°0’ 0”
R.A.	19h52m 5s
DEC	47°31’16”	64X
Lgst	7h52m38s	Stop
Alt.	0°0’ 0”
Azi.	0°0’ 0”

When the power is turned on you will see “G_ON” (GPS turned on) in the upper right corner of the screen. In about a minute, after the internal GPS communicate with the satellites, you will see “G_OK” on the screen. Both time and location are automatically set. Setup is finished in Alt-az mode.

If there is no GPS connected refer to 0.2 Getting Started on how to manually set up time and location.

The mount can also work in equatorial mode. Tilt the mount to the appropriate angle and point it to the polar star. Go to “Set up GotoNova”, select “Set Mount Type”, and select Equatorial mode.
