Headphone
To avoid risk of electric shock and to protect the diaphragm from being damaged, nothing
•
should be inserted into the grill on the headphone.
As with the amplifier, the headphone should be kept away from a high temperature environ-
•
ment ( ambient temperature should not exceed 40℃ or 104℉. )
• Keep the headphone away from substances such as alcohol, gasoline, acetone, other solvents,
sulfuric acid, sodium hydroxide or any other corrosive substances.
Do not treat the headphone violently as this may cause permanent damage to the internal
•
structure and invalidate the warranty.
• If the headphone should get wet, do not use a heat gun or hairdryer on the product as this
could permanently damage the headphone's diaphragm. Allow to dry naturally in a warm but
dry environment such as an airing cupboard.
• Do not use the headphone with wet hair.
If the product is to be left unused for a long time, please keep in the storage box and seal with
•
a moisture-proofing agent to prevent mould or corrosion.
