It is difficult to measure the exact Sound Pressure Levels (SPL) present at the eardrum in live applications. In addi-
tion 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.
