1. 1. Read the map. Each cell is rated Good, Fair, Weak, Unreliable or No fix for a receiver at street level. The key is under the map; Display changes the shading.
2. 2. Select a cell. The report shows one spot of it, with its own Worst, Typical and Best switch: whether a position works there, over the next 12 hours, and what blocks the sky.
3. 3. Look closer or wider. Zoom in (Z) analyses the selected cell in more detail. Zoom out (-) covers a wider area, up to 12 km from north to south.
