Directional keys

The directional keys allow complete control of the telescope at almost any step in the SynScanls operation. These controls are locked out when the telescope is slewing to an object. They are normally used to initially align, center objects in the eyepiece, and manual guiding. The left and right directional keys can also be used to move the text curserwhen entering data to the hand control.

Scoll Keys (Fig.e)

The up and down scroll keys allow you to scroll up and down within the menu tree or selections.

Dual Purpose keys

These keys range from the middle to the bottom of the hand control. They serve two distinct purposes -data entry and quick reference hot keys.

TOUR key (Fig.0 takes you on a preset tour across the sky you are currently under.

RATE key (Fig.0 changes the speed rate of the motors when the direction keys are pressed. There are 10 speeds to choose from: 0 (slowest) to 9 (fastest).

UTILITY key (Fig.0 shows functions such as Show Position, Display Time...etc. USER key (Fig.0 gives access to up to 25 user-defined coordinates.

ID key (Fig.0 identifies the object the telescope is currently pointing to.

NGC, IC, M, PLANET, and OBJECT keys (Fig.g) allow direct access to SynScanT" database of over 13,400 objects.
