Maintenance

∫ The product
≥ Occasionally wipe the terminals on the charger and main unit with a dry cloth.
≥ Normally, wipe clean with a soft, dry cloth. When there is noticeable dirt, use a soft
cloth dipped in a solution of a neutral detergent, diluted with water by a ratio of 5 or 6
to 1, wring well and wipe. Dry with a cloth after this.
≥ Take care as printing and paint can be removed if liquids such as alcohol, benzene,
thinners, or pesticides get on the casing.
≥ When using chemical wipes, etc., carefully read the instructions that come with the wipes.
∫ The included earphone tips
≥ Earphone tips can easily become blocked with earwax and other dirt. If the tips
become blocked, not only will sounds become lower and you won't be able to hear,
but this also may lead to malfunction of the earphones. Remove them occasionally
and wash in warm water, then wipe clean with a dry cloth.
≥ The earphone tips are consumables, so may fade or harden. Replace with new ones
if this happens.
