Using the Zoom H2N is quite easy. First, insert two standard AA alkaline or NiMH rechargeable batteries, or connect it to an AC adapter. Then, select your preferred recording mode based on your needs, like X/Y for stereo or 4 - channel surround for a more immersive sound. When recording, you can adjust the input gain manually or use the auto gain feature. For quick monitoring, use the built - in reference speaker. Remember, an SD card is not included, so you'll need to provide your own. Keep the recorder away from extreme temperatures and moisture. If the power fails or the card is removed, the data recovery function will save your data. After use, turn it off and store it in a safe place. To maintain it, clean the exterior with a soft, dry cloth.
