Please note that with the long URL for the database page that I

provided, the link got split. You will need to cut and paste the

last part of the link to get at the page.

One more thing I forgot to mention. The batteries normally have a

useful life of about 5 years. When the database corrupts on a newer

keypad, it can be because something has knocked the battery so that it

temporarily loses contact. If you have recently dropped the keypad,

for example, this may be the case. It is then a good idea to try

reloading the database to test the battery, especially if you have a

newer unit. Once the database is reloaded, power the unit down for a

short while. Then power up; go to Objects; choose a Messier object

that you know is presently in the sky (for us in Rockford we use M82

which is circum-polar); press GOTO and see if the data is correct.

If your keypad battery is dead, the data will have re-corrupted (or

will re-corrupt within a few days). If your keypad is 5 years old,

or older, you can be reasonably confident that the battery needs

replacement.

Howard --



My keypad is about 4 years old, and so far is working fine. Is it

possible to replace the battery without losing the database, or am I

going to have to reload it anyway (and so might as well wait for it to

fail)?



Thanks,

-- Jeff.

Please excuse the extreme naivity in this question; what cable or

connector do I have to have to link my handpad to my computer to do

the download of the data base? I didn't find this in my manual with

a cursory look last night. Thanks

Your keypad does not connect directly to your computer. The

firmware uploads must go through your control box. You need a

straight through (as opposed to reversed or null modem) serial cable

between the computer and the top - COM1 - port of the control box.

The keypad simply attaches to the control box in the normal manner.

Please read and print off the instructions for the downloads that

are on the website. Follow the instructions very carefully. You

will want a printed copy since you will be shutting down your

browser during the process. If your computer does not have a

serial connection, many USB / serial adapters are available at

computer stores.
