1. Microphone Ports: The tiny holes on top are the microphones. Do not poke them. Use a soft toothbrush to gently remove pocket lint.
2. Battery Longevity: Do not leave the recorder on a charger overnight. Once the battery icon shows full (3 bars), unplug it.

8. Testing Strategy

• Use screening tests (X-ray fluorescence, XRF) for initial checks on incoming components and finished goods.
• For ambiguous or failing XRF results, perform laboratory testing (ICP-OES/ICP-MS) on homogenized samples to determine concentrations.
• Sampling plans: define sample sizes and frequencies based on risk, supplier history, and critical components.
• Accredited labs: use ILAC-accredited labs for definitive testing and keep certificates on file.

• REC (Red Button): Starts and pauses recording. A flashing red LED indicates recording in progress; a steady LED means pause mode.
• Stop/Menu: Ends the current recording session and saves the file. A long press enters the settings menu.
• A-B / Folder: Switches between recording folders (A, B, C, D). Use this to organize lectures, meetings, or personal memos separately.
• Volume +/-: Adjusts playback volume, not recording sensitivity.
