7. Troubleshooting 1. The oscilloscope cannot be turned on. It may be that the battery is completely exhausted. At this time, even if the oscilloscope is powered by the power adapter, the oscilloscope cannot be turned on. You need to charge the battery first, and do not turn on the oscilloscope. - Page 20 RUN/STOP. Check whether the trigger mode of the trigger mode menu is normal or single, and the trigger electrical level is out of the waveform range. If so, center the trigger electrical level or set the trigger mode to automatic. In addition, you can press Auto to automatically complete the above settings.

Warning: Please make sure the instrument is dry before re-energizing to avoid electrical short circuit or personal injury caused by moisture. Charging and Replacement of Battery If you want to store the oscilloscope for a long time, it is recommended to fully charge the lithium battery before storing.
- Page 23 Note To avoid overheating of the battery during charging, the ambient temperature must not exceed the allowable value given in the technical specifications. Replacement of Lithium Battery Generally, the battery does not need to be replaced. However, when necessary, it can only be replaced by qualified personnel, and only lithium batteries of the same specification can be used.
