Wildgame Innovations S2 is a 2‑megapixel trail camera that uses four C‑cell batteries, a passive infrared (PIR) motion sensor, an on‑board strobe flash with ~20 ft range, and 16 MB of internal memory plus optional SD card storage. Common failure modes include battery drain or low voltage causing intermittent power loss, flash malfunction due to capacitor degradation or LED wear, PIR sensor drift leading to false triggers or missed detections, and SD card read/write errors that corrupt image files. First‑check steps: verify the C‑cell batteries are fresh and properly seated, measure the unit’s output voltage; inspect the flash circuitry for visible damage or loose connections; test the PIR sensor by placing a warm object near it to confirm motion detection; finally, remove and reinsert the SD card (or try a known good card) while reviewing any error codes displayed on the LCD.[oss-gpt-20b]
