WARNING!
USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE.
USE AS LOW A VOLUME AS POSSIBLE.
In order to use this system safely, avoid prolonged listening at excessive sound pressure levels. Please use the following guidelines established by
the Occupational Safety Health Administration (OSHA) on maximum time exposure to sound pressure levels before hearing damage occurs.
90 dB SPL at 8 hours
95 dB SPL at 4 hours
100 dB SPL at 2 hours
105 dB SPL at 1 hour
110 dB SPL at 1 hour
115 dB SPL at 15 minutes
120 dB SPL ? avoid or damage may occur
It is difficult to measure the exact Sound Pressure Levels (SPL) present at the eardrum in live applications. In addition to the volume setting on the
PSM, the SPL in the ear is affected by ambient sound from floor wedges or other devices. The isolation provided by the fit of quality earpieces is also
an important factor in determining the SPL.
Here are some general tips to follow in the use of this product to protect your ears from damage.
? Turn up the volume control only far enough to hear properly.
? Ringing in the ears may indicate that the gain levels are too high. Try lowering the gain levels.
? Have your ears checked by an audiologist on a regular basis. If you experience wax buildup in your ears, stop using the system until an
audiologist has examined your ears.
? Wipe the ear molds with an antiseptic before and after use to avoid infections. Stop using the earphones if they are causing great discomfort
or infection.
