Q1: What are the key features of this voice recorder? What situations is it suitable for?
A1: This voice recorder features a bidirectional microphone design. This enables it to capture sound from two directions simultaneously. It is particularly well‑suited for one‑on‑one conversations, interviews, small meetings, and similar scenarios. It offers a recording time of approximately 20 minutes. It has a recording range of up to 5 metres. It is lightweight and portable — and features one‑button operation.
Core positioning: Designed for short, efficient recording of two‑person conversations. It is not an all‑day recording device. It is a convenient tool — designed for specific scenarios.

Q2: Why is the recording time limited to 20 minutes?
A2: This is a deliberate design choice. It makes the device suitable for short‑duration recording scenarios.
Design rationale: 20 minutes is sufficient to cover most interviews, small meeting discussions, classroom segments, and capturing fleeting ideas.
Usage recommendations:

• If you need to record longer content, you can record in segments — save one segment before continuing to record the next.

• It is best suited as a supplementary recording tool — rather than a 24/7 recording device.
  Advantages: The short‑duration design makes the product more compact. Operation is simpler. File management is more convenient.

Q3: What does a recording range of 5 metres mean? How does it perform in practice?
A3: 5 metres refers to the maximum distance at which clear recording is possible — under ideal conditions.
Testing environment: Quiet indoor setting — normal speaking volume — no obstructions.
Practical usage:

• Within 1‑2 metres: Clear sound quality — voices stand out.

• Within 3‑4 metres: Distinct and recognisable — with slight ambient noise.

• At 5 metres: Sound can be recorded — but may be mixed with background noise.
  Recommendation: Place the recorder between speakers — or close to the main speaker — for best results.

Q4: What does a bidirectional microphone mean? What are its advantages?
A4: A bidirectional microphone can pick up sound from two directions simultaneously. It is specifically designed for dialogue scenarios.
How it works: The microphone array faces two directions — front and back — to capture what both parties are saying.
Advantages:

• Interview scenarios: The journalist and interviewee face each other. Bidirectional pickup ensures balanced audio from both sides.

• Small meetings: Placed in the centre of the table — it clearly captures speech from both sides.

• Classrooms / lectures: Placed between the lectern and the audience — simultaneously recording the lecturer and students’ questions.
  Difference from omnidirectional microphones: Bidirectional microphones focus more on the two parties in conversation — reducing interference from background noise.

Q5: How do I export the recording files? What formats are supported?
A5: Connect directly to a computer via USB. It is plug‑and‑play.
Export method: Connect to a computer via a USB cable. The recorder is recognised as a USB drive — allowing you to copy the recording files directly.
File formats: MP3 and WAV formats — compatible with computers, mobile phones, and media players for direct playback.
File naming: Files are automatically named according to the recording time — making them easy to locate.

Q6: Can this voice recorder record whilst charging?
A6: Not recommended. Recording time is limited to 20 minutes. A full charge is sufficient for multiple uses.
Reason: Recording whilst charging may affect recording quality. Prolonged use whilst charging may reduce battery life.
Recommendation: Fully charge before use. Recharge promptly after daily use — to ensure it is ready for the next session.

Q7: How is the voice recorder charged? How long does the battery last?
A7: USB charging — with a built‑in lithium battery.
Charging method: Charge via a USB cable — connected to a computer or charger.
Charging time: Approximately 1‑2 hours to fully charge.
Battery life: A full charge allows for approximately 20 minutes of continuous recording — multiple recordings are possible, with cumulative duration.
