| Test | How to Perform | Pass Criteria | |------|----------------|---------------| | Record‑Loop Test | Set the cam to continuous mode (record 30 s per clip). Let it run for 55 clips. | No red LED; new clips appear in the file list. | | Playback via PC | Connect to PC, open the “HZCAM” drive, play back a few random files. | Files open without corruption. | | Battery Drain Test | Run the cam for 2 hours on battery. | Voltage stays above 3.5 V; no unexpected reboot. | | Heat Check | After 30 min of recording, feel the rear panel. | Temperature ≤ 45 °C (touch‑comfortable). |

If any test fails, repeat the corresponding step or consider a full flash replacement.

| Question | Answer | |----------|--------| | Can I reset the cam without opening it? | Yes – a firmware re‑flash or soft reset often clears the issue. | | Will resetting erase my existing footage? | The index reset only clears the catalog; the raw video files remain on flash until overwritten. Back up important clips first. | | Is the 49‑video limit a hardware spec? | It’s a software‑implemented safety buffer for the 8 MB internal memory. Updating the firmware or adding an SD card removes the limit. | | What if the unit still won’t power on after the fix? | Likely a dead battery or damaged power‑regulator IC; replace the battery or consult a repair shop. |
