How to access service

Hello everyone,

I’m working on a GE LOGIQ E9 (software R3.1.2).

The system boots normally into the application, but immediately shows a System Error: “DC Offset Calibration required” and blocks clinical mode.

Current status:

System OS and application boot correctly

No GRUB or BIOS issues

Original system SSD is installed

Error appears at startup before imaging is possible

What I already tried:

Ctrl + Alt + D during boot

Ctrl + Alt + Shift + D / S

Ctrl + Alt + F2 / F3 to access Linux console

Phone key service access

Booting with GE software CD / USB (system does not auto-boot from media on E9)

None of the above gives access to Service / Diagnostic mode, so I cannot run DC Offset Calibration.

Question:

What is the correct way to access Service or Engineering mode on LOGIQ E9 R3.x when the system is blocked by DC Offset error?

Is there a console command or startup flag to force DC Offset calibration?

Does this condition require a specific service login or service tool?

Any guidance from experienced LOGIQ E9 engineers would be greatly appreciated.

Thank you in advance.

Hello

Yes, in order for the service to be available, I first need to change the user from USR to ADM. Then the Service tab will appear on the touch panel in the Utility tab.

You possibly have a front end board or main power supply defect. Clinical use should be possible even without a DC offset calibration from my experience.

Hi, try this procedure.

6-3-2-1 DC Calibration Procedure

1.) Disconnect all connected probes.

2.) Power on the LOGIQ E9.

3.) On the Touch Panel, select Utility -> Service to access CSD.

4.) Log in as GE Service, enter current password

4A.) ADM logon: password is ulsadm or echo (all lower case) or no password at all

5.) Select Diagnostics tab.

6.) Select Service -> Diagnostics.

7.) Select the “+” before Service Diagnostics folder to open the list of choices.

8.) Select the “+” before Analog Receive to open the test choices for the analog receiver.

9.) Select DC Offset Calibration and then follow the on-screen instructions.

I hope this helps you
