Compass mode makes use of four buttons. Two buttons are used to control vertical position. When the required vertical position has been reached a third button is pressed to zoom in. After zooming in on the location, the user once more selects vertical position. A forth button zooms out if an error is made.
Konpas moduan lau botoi erabiltzen dira. Bi botoi posizio bertikala kontrolatzek erabiltzen dira. Behin nahi den posizio bertikala lortuta, hirugarren botoi bat sakatzen da zooma handitzeko. Posizio horretan zooma handitu ondoren, erabiltzaileak berriz hautatzen du posizio bertikala. Laugarren botoi batek txikitzen du zooma, akatsik egon bada.
