Time, TZ, etc.
Or just Menu -> Utilities -> Factory Settings (follow instructions). Then it will prompt for location on next start.

Perhaps my next project should be to find out if there is a downloadable firmware upgrade adressing this issue. I plan to use this mount in my peripatetic travels around the country every summer, so I was looking for an easy way out.
Thanks again and clear skies to you both.

The Lat/Long settings are not that important. Just pick something from the list that is kind of close to where you are observing. The mount will still work perfectly fine. I set my CG-5 up the other night at my local clubs dark sky site.
My procedure . . .
1. Point the mount towards Polaris.
2. Get it kind of level.
3. Make sure sure you can see Polaris through the polar scope hole (I don't have a polar scope)
4. Connect the mount to the battery.
5. Pick a city from the list that is kind of near where you are.
6. Set the time to something close to the actual time.
7. Make sure the date is correct.
8. Pick some good alignment stars.
Sure, the first couple of alignment stars may be a bit off, but that doesn't matter--not to the alignment algorithm. Use the hand controller to center them up into the FOV. (This is where it helps to pick alignment stars that you are familiar with.) As you progress through the 2 alignment stars and 4 calibration stars, you will notice that the accuracy keeps improving until new stars are dead center in the FOV.
Since I was going to be out for a while the other night, I carefully centered the stars at 150x. (I usually use a 17mm Nagler T4 that only yields about 50x with a wide FOV that makes centering an inexact art, but this was a special occasion so . . .) Still the whole procedure took less than 10 minutes. After 6 hours, new goto's were showing up in the center of the FOV.
In the spirit of full disclosure, I did sync on an object after 3-4 hours because in one part of the sky objects were not in the absolute center of the FOV after a goto.

I didn't ask the obvious question. What version of the HC firmware are you running?
In 4.16 the following works:
Immediately after powering up (before alignment), or from the Advanced GT screen (after alignment):
Press the [MENU] button
[UP] or [DOWN], if necessary, to
Scope Setup (you may have missed this step)
[UP]/[DOWN], if necessary, to
You should be at the Time-entry prompt.
Now you should be prompted to enter Lat/Lon for a Custom Site. Press [UNDO] again if you want to choose from the City Database.
[UNDO] from the Select One: City Database/Custom Site screen allows you to bail out.
I don't think this is in the manual. Someone here mentioned how to get there in another thread.
