2.2 Hearing Damage
This equipment can deliver sound pressure levels in excess of 110dB. At this level
permanent hearing damage can occur and exposure to this level of sound, even for
relatively short periods (see table below), can be harmful. Of equal importance to the
maximum level of sound is the exposure to high levels of sound for extended periods.
There are no international agreed limits and different countries have different limits
measured in differing ways.

It is also important to note that the effect of exposure to sound is cumulative.
Having listened to sound, for example, for 15 minutes at 105 dB then further
exposure to noise levels above 80dB should be avoided until the next day.
3. Unpacking
This Quested product has been carefully manufactured, tested and packed to ensure
it arrives in a flawless condition. The component parts of the packing have been
