The DST switch works the same as above, check it if the specified location currently has daylight saving time in effect, uncheck it otherwise. If you use Planetarium to calculate the sky for the place you currently are and you have set the Palm clock to the time zone of your current location, these two entries are the same. Check or uncheck both DST switched according to the season. Then you need to enter latitude and longitude of San Francisco and you're set. Azimuth is measured in degrees, counted eastwards.
Negative values are below horizon.
These two values are shown graphically. The circle at the right of the display shows the azimuth of the objects on a compass scale. To use this dial, turn the Palm Organizer so that 'N' points to the north. The semicircle on the left shows the altitude. Hold your Palm Organizer upright so that 'Z' points to the zenith.
