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 lev- els. Please use the following guidelines established by the Occupational Safety Health Ad- ministration (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 1/2 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 earphones is also an important factor in determining the SPL in the ear.

Here are some general tips to follow in the use of this product to protect your ears from damage:

1.Turn up the volume control only far enough to hear properly.

2.Ringing in the ears may indicate that the gain levels are too high. Try lowering the gain levels.

3.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.

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.
