    • Check the battery level. Replace if low.
    • Ensure the start mode is correctly configured (button-press, timed, or delayed).
    • If using button-press start, press and hold the button firmly until the "REC" indicator appears on the LCD.
  • No PDF report generated after connecting to PC:
    • Ensure the device is properly connected to a functional USB port.
    • Try connecting to a different USB port or computer.
    • Verify that a recording session was completed before attempting to generate a report.
  • Inaccurate temperature or humidity readings:
    • Ensure the sensor is not obstructed or exposed to conditions outside its specified operating range.
    • If consistent deviations are observed, the device may require recalibration. Contact Elitech support for assistance.
  • LCD display not working or showing garbled text:
    • Check the battery level and replace if necessary.
    • If the issue persists after battery replacement, contact customer support.
