Just to confirm:

For the LX200:

1. Latitude is on the top line.
2. Longitude is on the second (bottom) line.
3. Longitude is entered as plus for west longitude (and east longitude is entered as 360 - longitude).
4. The leading 0 is required for west longitudes from 0 to 99 58
5. The angles are degrees and minutes
6. The GMT shift is the 'hours to add to local time to get GMT'. Values for east longitude should be negative.
