• Sørg for, at batteriet er tilstrækkeligt opladet. Tilslut enheden til en strømkilde, og lad den oplade i mindst 30 minutter, før du forsøger at tænde den igen.
• Try a different charging cable or power adapter to rule out accessory issues.

7.2 Poor Recording Quality

• Sørg for, at mikrofonerne ikke er blokeret.
• Check the recording environment for excessive background noise. The device's denoising algorithm works best within its design parameters.
• Verify that the recording distance is within the recommended 15-meter range.

7.3 Transcription Errors or Inaccuracies

• Ensure the correct transcription language/dialect is selected.
• Speak clearly and at a moderate pace during recording for best transcription results.
• Minimize background noise during recording.

8. Brugertips

• Fortrolighed: The SR302 Pro stores recordings and transcriptions locally. Files can only be copied via a data cable, making it suitable for confidential scenarios such as government meetings or closed-door discussions where network access is restricted or security is paramount.
• Optimal Recording Placement: For best results, especially in larger rooms, position the recorder centrally to leverage its omnidirectional microphones for 360-degree sound pickup. For specific speakers, orient the directional microphones towards them.
• Batteristyring: While the 2000mAh battery offers significant usage time, for long events, consider carrying a portable power bank to ensure uninterrupted recording.
