Cold vs. Warm Start. When the eXplorist is turned on, one of the first things it does isto find out which satellites are overhead, along with their relative position. It does thisby using a built-in satellite almanac. This almanac, when given the current date, timeand approximate position, can provide the eXplorist with information on which satellitesare overhead and their approximate relationship to the eXplorist. Now with informationon satellite availability, the eXplorist can begin setting its internal satellite channels toreceive satellite transmissions.Cold Start. Cold start is defined as when the eXplorist does not have anapproximate position to use when referring to its almanac. This can occur when:• The eXplorist is turned on for the first time after purchase. The memory iscleared prior to shipping so that any position that may have been in theeXplorist is set to a null value.• If you have cleared the eXplorist's memory, (found in Preferences) all ofthe memory will be cleared and the last computed position will be set to anull value.• If you have traveled with your eXplorist with it turned off, the last positionsaved may be so far away that when the eXplorist begins looking forsatellites, the ones it is expecting to find are not there. (As a rule ofthumb, any time you move for more than 500 mi [804.7 km] with theeXplorist turned off, there is a good chance that it will start up using acold start.A cold start should take no more than 2-3 minutes to compute the initial positionfix.Warm Start. Warm starts are when the last position calculated before theeXplorist was turned off is still in memory and you are in the same approximateposition. Most of the time that the eXplorist is turned on, it will be in its warm-start mode. With a clear view of the sky, the eXplorist should compute itsposition in a matter of seconds.ConclusionThis concludes the initial startup procedure for the Magellan eXplorist 600. Once the Mapscreen is displayed, you have successfully initialized the eXplorist and are ready to go.Now would be a good time to familiarize yourself with the different navigation screens(using the NAV button) and to set any preferences that may be different from the factorydefaults.Starting Up 14
