can any one help the cmoss battery failed and the scope has lost its set up and only boots to blue intro screen.
Can any one tell me how to fix the problem

 

For starters... Is the battery spot-welded into the circuit, soldered, or have a slip-in clip arrangement.

Caution : use deliberate moves when changing a power supply for a Cmos circuit... so you don't get a repeatable pulse that may "retard" the circuit...
Does it have a ROM chip to reboot the startup protocols ?? Cmos has a bad habit of ' losing its mind ' when deprived of power.

 

When the unit is powered off , you push on the “Hold all” button and start on the unit, after two beeps you let off on “ hold all” button
The unit starts and on “ cold start” and will reset the memories


The battery on the processor board when 100% dead, will auto boot as described. When it is 50% dead, you will see strange things occur and if the system is still functional, the COLD BOOT method described will usually cure the problem as long as the scope is on.
