Precautions
Please ensure the mouthpiece is clean before use to prevent blockage by dust or foreign objects.

The tuning whistle serves as a standard pitch reference tool, it produces the standard pitch of D. Final tuning must still be performed manually using the erhu's tuning pegs or a fine-tuning device.

Do not drop or squeeze the whistle forcefully; severe impact may cause deformation or affect pitch accuracy.

Store in a dry place to prevent oxidation or rusting of the mouthpiece.

Small parts should not be swallowed to avoid accidental inhalation.

As measurements are taken by hand, there may be a margin of error of 1-2 mm, please consider this carefully before purchasing.

There may be slight variations in appearance between different batches of products (such as the colour of the lanyard or the style of the protective case), but this does not affect normal use.

As the tuning whistle is a personal instrument, and to ensure hygiene, returns or exchanges will not be accepted once the product has been opened and used, unless there is a quality issue.

We recommend wiping the mouthpiece regularly with a soft cloth to keep it clean.
