OSD time-out refers to the feature on a monitor or display that automatically turns off the on-screen display menu after a certain period of inactivity. This is a power-saving feature that helps conserve energy and prevents the on-screen display from being left open indefinitely. The time-out period can usually be adjusted in the monitor's settings to suit the user's preferences. **

72V can charge with 9V because the 9V source has a higher potential difference than the 72V battery. When connected in parallel, the 9V source will push current into the 72V battery, causing it to charge. This process is possible because the voltage of the charging source needs to be higher than the voltage of the battery in order for the charging to occur. **

To charge a 72V battery, you will need a charger specifically designed for that voltage. Make sure to use a charger that is compatible with the chemistry of your battery (e.g. lead-acid, lithium-ion). Connect the positive and negative terminals of the charger to the corresponding terminals on the battery, making sure to observe the correct polarity. Follow the manufacturer's instructions for the specific charger you are using, and ensure that the charging process takes place in a well-ventilated area and is monitored for safety. **

To remove the OSD Lock symbol on your monitor, you can try pressing and holding the Menu button on your monitor for 10-15 seconds.

If you are still unable to remove the symbol, refer to the monitor's user manual for specific instructions on how to disable the OSD Lock. **

If you are unable to unlock the OSD using these methods, you may need to contact the manufacturer for further assistance. **
