Attention
This speaker is designed for underwater use only. Do not use in air as it may be damaged.
The optimum depth is about 2m.
Please note that the maximum depth may exceed 3m depending on the conditions in places where there are waves.
The front surface of the main unit (the surface with the Fostex logo) is the vibrating part, so please do not apply any external pressure or shock to it.
When using the product without fixing the main unit, please do not pull on the speaker cord when moving the product. Doing so may cause malfunction.
*For safety reasons, be sure to ground the speaker cord to earth ground.
This product is designed to reproduce music and sound underwater. Use of this product for research purposes, such as playing sine waves for long periods of time in experiments, may result in malfunction.
The sound speed in water is about 10 times faster than in air, so the pitch of the sound may change, but this does not indicate a malfunction.
*This product complies with the European RoHS Directive.
