Be careful when turning on the headphones volume control. Before placing the
headphones over your ears, set the volume control to minimum, then slowly 
increase until you reach a comfortable level.

Use only the supplied power adapter. Failure to use the correct power adapter
can result in fire and permanent damage to the transmitter unit.

Do not over-drive the headphones. Like any speakers, playing the sound
too loud on the headphones may cause damage to both the headphones and
your ears. Please take care to listen at moderate levels.

WARNING: Long term exposure to loud music or other sounds in headphones may 
         cause hearing damage. It is best to avoid extreme volume levels when
         using headphones, especially for extended periods. Over time, your 
         ears adapt to the volume level, so a level that may not cause initial
         discomfort might still damage your hearing.
