MODE

This key allows the user to change the controller’s current mode. Modes are used to access the

various functions of the controller. For example, when MANUAL mode is active the user can

manually jog the antenna; When SETUP is active the user can program satellite position data

into the controller’s non-volatile memory. The modes are divided into two groups: Operational

Modes (which include MANUAL, AUTO, REMOTE, and TRACK modes) and Programming

Modes (which include SETUP, DELETE, RESET, and CONFIG modes). To change from one

GROUP to the other DEPRESS THE MODE KEY FOR AT LEAST FIVE SECONDS AND THEN

RELEASE IT. To toggle between the modes in a given group rapidly depress and release the

mode key.

SCROLL UP, SCROLL DOWN

These keys are used to scroll up or down through a list of items.

YES, NO

These keys are used to supply an answer to a yes or no type question.

ENTER

This key is used to select an entry from a list, terminate a prompt for some action by the user, or

to complete the entry of numeric data.

0-9, DECIMAL POINT (with the stop key), BKSP

These keys are used for numeric entry. The BKSP key causes the cursor to move one column to

the left writing over the character that was there.

SPEED

This key toggles the az/el speed from fast to slow and vice versa.

AZ CW, AZ CCW, UP, DOWN

These keys are used to manually jog the antenna in certain modes. CW refers to clockwise and

CCW refers to counter clockwise. The sense of azimuth rotation is as seen by an observer

located above the antenna. On early versions of the controller the AZ CW, AZ CCW, UP, and

DOWN labels were not present on these keys. On these controllers (when certain modes are

active) the left arrow key initiates ccw azimuth movement, the right arrow key initiates cw azimuth

movement, the up arrow key initiates up elevation movement, and the down arrow key initiates

down elevation movement.
