Chart speed slow on 798

I just put the new update on my 798ci SI Combo – Update (version 4.960).
It seems like the chart speed is way down from before – at full 10 it’s very slow, at 5 it almost stops. Everything else seems to be working fine. Does anyone have idea what the problem may be and how to fix it?

Hi,
I’ve had the same level installed in my 797c since it came out in June and have not noticed your problem. PS: Just to check, I was just out to the garage to check and my (sonar) chart speed is working fine. You might want to try backing out the firmware to an older level (4.780?) and then reloading level 4.960 again.

There is available on the side imaging soft website http://forums.sideimagingsoft.com/index.php?PHPSESSID=ichbgabcljhsm35h1ii464q5t0&
six (6) levels of firmware (current plus five older levels) for the 798c (or 798ci). Note: You will have to join the group to get access to that data. Also, be sure to do a “restore defaults” before and after each load.

I carry three (3) levels of firmware for my HB units with me (on the boat) so I can do “hot swaps” while I am on the water. This came in handy when there was the shallow water performance issue a while back (and since fixed). This might be overkill now since my HB’s run GREAT!

Take care,
Roger

Thanks Roger. I will try to do what you suggested. I did restore defaults before the upgrade but I didn’t know you should do it after the upgrade as well.
