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 guide- lines established by the Occupational Safety Health Administra- tion (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

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 this Personal Monitor unit, the SPL in the ear is affected by ambient sound from floor wedges or other devices. The isolation provided by the fit of quality earphones is also an important factor in determining the SPL in the ear.

Follow these guidelines in the use of this product to protect your ears from damage:

1.Turn up the volume only to the point where hearing is comfortable.

2.Ringing in the ears may indicate that the levels are too high. Lower the volume level.

3.Have your ears checked by an audiologist on a regular basis. If you ex- perience wax buildup in your ears, stop using the system until an audiolo- gist has examined your ears.

4.Wipe the earphones with an antiseptic before and after use to avoid infections. Stop using the earphones if they are causing great discomfort or infection.
