Q1: Why is a radio important for the HKDSE listening exam? What are the advantages of the CORUS DSE-555A?

A: A stable, clear, and compliant radio is essential for the HKDSE listening exam. The CORUS DSE-555A is a highly rated "exam essential" with over 10 years of strong reputation. Key advantages include:

  • Professional US radio chip for high sensitivity and strong anti-interference.
  • Digital frequency display to prevent tuning to the wrong channel.
  • Patented "Exam Mode" that automatically locks at the best exam frequencies and forces to Mono mode.
  • 1.44-inch color screen showing remaining battery life and signal strength.
  • Ultra-long battery life with over 30 hours of continuous playback.

Q2: What is the difference between traditional "manual tuning" radios and the CORUS DSE-555A digital radio?

A: Traditional radios require manual tuning, making it easy to tune to the wrong channel if your hands shake from nervousness. The CORUS DSE-555A uses advanced digital technology to fix this issue below.

  1. Shows the exact frequency in numbers (like 96.9 MHz) on the screen.
  2. Automatically identifies and saves all HKDSE exam frequencies during startup, and can be factory reset to find new ones if RTHK Radio 2 ever changes its frequencies.

Q3: How long does the DSE-555A battery last? How do I avoid sudden shutdown during the exam?

A: The radio uses mature power-saving technology to provide up to over 30 hours of continuous playback. The color screen displays remaining battery level, so you can easily check if you have enough power before the exam, perfectly preventing any sudden shutdown.

Q4: Does the DSE-555A come with earphones? Are they comfortable?

A: Yes, every unit includes high-quality in-ear earphones and three sizes of ear tips (large, medium, small) to fit different students. The in-ear design blocks out background noise in the exam hall and stays comfortable without causing ear pain, even after long periods of use.

🏆The Best Exam Frequency

Q5: How do I choose the best exam frequency?

A: First, check the frequency coverage map for different areas in user manual. The suggested frequency is usually written on the exam hall blackboard, so you should tune in and test it first. Since some exam venues sit between transmitters, you might receive multiple frequencies clearly. The CORUS DSE-555A helps you easily find the best one by checking the signal strength indicator on the top left and confirming with the audio quality.

Here is how to find the best frequency(Manually or Automatically):

1. Turn on the radio and short-press the power button to switch to Exam Mode.

2. Since Exam Mode has already identified all RTHK Radio 2 frequencies in Hong Kong, your best exam frequency will definitely be one of them. You can use two methods—[Manual] and [Auto]—to find the frequency with the best reception.

Manual:

- Use the scroll wheel to tune to each frequency. Then, by the sound quality and signal strength indicator to help you confirm the best exam frequency.

Automatic:

- To search automatically, press and hold the scroll wheel for 3 seconds to let the system find the best frequency in 10 to 20 seconds.

Q6: How do we know the best frequency of the exam venue?

A: First, you can check the coverage areas for different frequencies in user manual. Also, the suggested frequency should be written on the exam hall blackboard. You can tune to that frequency to test the sound, as it is very likely to be your best choice.

Q7: Why does the auto-search result sometimes differ from the blackboard's suggested frequency?

A: Your exam venue might be covered by two transmitters or more, meaning both frequencies work fine. For example, some venues in Kowloon East can receive both 94.8 and 96.9 MHz clearly. In this case, use the signal strength indicator and your ears to decide which frequency sounds better.

Q8: Is the auto-search result always accurate?

Q9: Does the auto-search result reliable?

A: Yes, but the electronic devices like mobile phones (even on silent mode) can sometimes affect its accuracy.

Q10: Can I test all 7 frequencies one by one to find the best one?

A: Yes, absolutely. We highly recommend doing this to ensure you get the clearest reception.

Q11: What is the safest approach for the listening exam?

A: Bring two radios and turn both on during the exam, keeping them slightly apart. This lets you compare their reception on the spot and gives you an immediate backup if one radio suddenly stops working.
