How to use

For Both Classic and Pro

1. Install two new 3A batteries.

2. The headphone jack must be fully inserted until the metal edge is no longer visible in the horizontal position to ensure a correct connection (if it is not tightly inserted, there may be noise or no sound).

3. Check that the headphone cable remains straight and free of twists.

4. After briefly pressing the top switch, you can listen to the best signal of Radio Hong Kong 2 Examination Channel (RTHK2 FM 94.8Hz-96.9Hz) in about 3 seconds.

 

For Pro version only:

• After receiving the test radio signal, you can press the triangle button on the upper right corner of the body to switch and listen to the test channels in seven different locations in sequence.
