1.7.1 Controls
The GI 275 features a 2.69" circular capacitive touchscreen and an Outer and Inner Knob in the lower left
corner. The Inner Knob can be pushed. All operations are done with the Knobs or touchscreen. The touchscreen
can be operated with bare fingers or gloves made for capacitive touchscreens.

Swipe
Scroll
Pinch &
Stretch
A touch can select a menu, activate a command key or data entry field, display map feature
information, or select a button.
Certain momentary controls (e.g., directional arrow keys, CRS Button, HDG Button)
provide a secondary touch and hold function.
Touch key and hold finger in place. Lift up once the desired action occurs.
Use this gesture for scrolling and increasing/decreasing values continuously.
Touch object with finger, slide finger across screen, then lift up.
A swipe is a smooth motion used for viewing and scrolling lists, panning across a map, or
opening the menu.
This is similar to a swipe, except the finger leaves the screen after a quick upward or
downward motion.
Screen information moves at a fast speed, then slows down as it stops.
Scrolls through an item list faster than by pressing the scroll arrow buttons.
Touch any map or chart with two fingers at the same time. Then, bring fingers together
(pinch) or apart (stretch).
Stretch to zoom in and pinch to zoom out.
Use these gestures to magnify map features or identify multiple objects in close proximity.
