What to do if Innomed Medical Equipment turns off immediately after turned on?
- A
  Amy ThomasAug 21, 2025
  If your Innomed Medical Equipment turns off immediately after being turned on, it might be due to memory loss. Try switching the device on again; it will revert to the factory setup state with empty memory. Alternatively, the battery may have discharged, so try recharging it. If the issue persists after recharging, the charging circuit may be damaged, requiring you to check the power supply and charging circuit according to the documentation.

Why Innomed Medical Equipment does not turn on from battery?
- E
  Edwin RoyAug 23, 2025
  If your Innomed Medical Equipment does not turn on from the battery, first, ensure the device is connected to the mains and switched on, as the batteries may be completely discharged. If that doesn't work, check the battery and its charge state, as well as the fuse. If replacing the fuse, try to identify the reason for the burnout to prevent recurrence. If the battery is damaged and cannot be fixed, it should be replaced.

What to do if software does not start at all on Innomed Medical Equipment?
- C
  Crystal KlineAug 27, 2025
  If the software on your Innomed Medical Equipment doesn't start after turning on the device (with only a change in the display's tone), it could be due to memory loss. Try switching the device on again to revert to the factory setup state. If that doesn't work, charge the batteries, as the battery may have discharged or the charging circuit may be damaged. If the software in memory is damaged, download the original SW version. Also, check the soldering on the digital part of the Main Board, resolder the IC’s (except the processor), and if repair is not possible, replace the board.

What to do if charge LED is not on Innomed Medical Equipment?
- E
  Emily MullinsAug 28, 2025
  If the „CHARGE” LED is not on after connecting your Innomed Medical Equipment to the mains, verify the main cable and connection for any damage. Also, check the keyboard connection and the „CHARGE” LED on the keyboard to ensure they are functioning correctly. Finally, inspect the charging circuit for any potential damage.

How to fix Innomed Medical Equipment when it cannot be reprogrammed?
- D
  Diana JacksonAug 31, 2025
  If you're unable to reprogram your Innomed Medical Equipment, the reed-tube inside the device might be broken, preventing it from switching to boot mode. Disassemble the device and check the tube; replace it if necessary. As a temporary solution, if a replacement tube isn't available, reconnecting the reed-tube can place the device into programming mode. Also, verify the serial cable, PC, and download software settings, as the serial cable may be damaged or the PC serial port settings may be incorrect.

Why Innomed Medical Equipment always starts with a memory error?
- R
  ramirezjordanSep 2, 2025
  If you're experiencing a memory error each time you turn on your Innomed Medical Equipment, check the battery, its connection, and cable for any damage. Additionally, inspect the soldering on the digital part of the Main Board, resolder the ICs (excluding the processor), or replace the Board if necessary.

Why PC connection does not work with Innomed Medical Equipment?
- K
  Karen WaltersSep 4, 2025
  If your Innomed Medical Equipment isn't connecting to a PC, verify the Innobase version and the Innobase software module version to ensure they are appropriate. Also, check the device software version, and PC settings. The USB cable might be damaged. If problems persist, the USB interface may be damaged, requiring replacement of the Main Board.

What to do if appropriate voltage cannot be measured on Innomed Medical Equipment?
- K
  Kyle RobertsonSep 6, 2025
  If you cannot measure the appropriate voltage on the power supply output when connecting your Innomed Medical Equipment to the mains, it's possible that one of the fuses in the device has burned out. Replace the fuse and investigate the cause of the burnout. Also, check the mains voltage to ensure it is appropriate. If neither of these resolves the issue, the switching power supply may be damaged and require replacement.
