20 Most Recent Zeiss Humphrey Acuitus 5015 Autorefractor Keratometer Tested Calibrated Cornea Questions & Answers


These equipments use a sbc492 by Aaeon motherboard, and usually they shows a message like "Cmos battery Low".These motherboards use an RTC M48T86PCI with a internal lithyum battery, and just replace that component.Other problems may occur, like damaged slots, and or oxidation, but generally the 486 architecture is a huge way to work,Only clean change the memory(dimm 128 x 100mh)and enjoy.A simple way is a replacement with a new one by Intel, still easy to find in some inventorys, i have many in USA who can suply.

hope to solved

The batery is a integrated circuit that is soldered to the Mother Board. You should disolder that circuit in order to replace it

The battery can be seen circled in green in the photo below. It typically has a 10 year life. All apologies for the repeat text/ newbie here.d3d64cf2-75ae-495a-bf4e-dbcf5ee471c9.jpg

This is a brand name, not a specific device and model. That said, here is a page describing mode switch in the setup screen using the touch screen for a specific device. I assume a touch screen would have an icon for turning a device off.

The battery is soldered to the CPU. People from Zeiss Germany said that it needs to replace all the CPU. Now a days there is no longer spare parts for that instrument. I recommen you just change the day and time each time you turn it on
