To Save or Open a Card File Your entire "workspace" can be saved to a card file (*.CRD) so that you can easily maintain multiple cards. Click on File in the menu bar at the top of the window, and then either Open, Save, or Save As as is typically used in most Windows applications. Notes on GPS Triggering GPS triggering is one of the most powerful and unique features of the DMP-100. The following details will help you get the most from this feature. A GPS trigger will only occur when the trigger condition goes from "not valid" to "valid". This means, for instance, that if your card contains a GPS trigger for the LAX airport and you first power up on the ground at LAX, the trigger will not occur. You must first fly away from LAX, causing the trigger condition to become "not valid", and then the trigger will occur as you cross the specified trigger distance inbound. This was done specifically to allow you to have an audio track that is played as you return to base (at the end of a tour, for example), but which will NOT play when you first power up at the start of the flight. A GPS trigger condition is considered "valid" as soon as the specified distance is crossed. However, it will not become "invalid" until the distance increases to 20% more than the specified distance. This is to prevent undesired repeat triggering, or "chattering", if you are flying very close to the specified distance. For example, assume your card contains a trigger for 1 nm from LAX airport and is configured to "Trigger Always". As you approach LAX from any direction, the track will start playing as soon as your distance is less than 1 nm. The track will not trigger again until you have flown at least 1.2 nm away from LAX (1nm plus 20%) and then return to within less than 1 nm. Avoid overlapping trigger areas. If several GPS triggers become valid at once, only the last trigger in the list will actually play. The distance at which a GPS trigger activates may vary slightly from the distance you specified in CardPrep. Especially at higher aircraft speeds, there may be an error of almost 1 nm. In general, you should avoid using the very small distances available in CardPrep (1nm or less). Notes on Interrupting and Restoring Audio Tracks If a new audio track is selected (either manually or via any trigger) while another track is playing, the DMP-100 can resume playing the interrupted track after the new one finishes. This will only occur, however, for the most recently interrupted track. Any previously interrupted tracks will not resume, and must be manually restarted if desired. An interrupted audio track will resume if the attribute "Resume or Cancel" is set accordingly. See page 17 for a description of this attribute. For example, consider the following: 1) "Song #5" is selected manually, and starts playing. 2) Halfway through "Song #5", an external trigger selects "Speech #1".
