Acquire Current Position The DAGR obtains current position by simply turning the

DAGR on with an open view of the sky. While acquiring satellites, DAGR displays the SV Sky View page. After satellites are acquired, DAGR automatically transitions to the Present Position page with current position coordinates shown. An indication of when the DAGR has obtained current position is provided by:

– Position data fields of the Present Position page remain solid black text and

do not blink.– On the SV Sky View page, solid black horizontal bars indicate satellites being

tracked and data is collected; and Navigating shows at the top of the display.
