Questions and answers
I can not get the unit to power on at all. Battery is fully charged and turned on.
The Key-Disp KD58C may not power on despite a fully charged battery due to several reasons:
1. Power-on Password Enabled: If the power-on password is enabled, you must enter the correct password to turn on the display.
2. Connection Issues: Ensure the connector is properly linked and secure, as improper connection can prevent power from reaching the display.
3. Error Codes: Check for any error codes on the display (e.g., Error Code 30 for communication abnormality) that may indicate a malfunction.
4. Display Malfunction: If the display is not functioning properly, it may need repair.
If all these checks are in order and the display still does not power on, consider troubleshooting the electrical connections or seeking repair.

To reset the password for the Key-Disp KD58C display, follow these steps:
1. Access the settings by holding the ON/OFF button for 2 seconds.
2. Navigate to the power-on password settings (P2:0000).

4. Press the ON/OFF button to confirm each digit until the new 4-digit password is entered.
5. Once the password is set, press the ON/OFF button to save and exit.
If you are unable to recall the existing password, you may need to recover default settings by:
