Individuals with cardiac pacemakers and other similar medical devices should consult
with their physician before using any RF devices. Though the output level of this wireless
system is below 50 milliwatts, the proximity of the transmitter to the implant device could
pose a threat.
As with any wireless product, environmental conditions can reduce or in some cases
prohibit a successful connection between the transmitter

WARNING! USE AS LOW A VOLUME AS POSSIBLE.
PERMANENT HEARING DAMAGE CAN RESULT FROM USING THIS
SYSTEM AT EXCESSIVE VOLUMES.
For safe operation of this in-ear monitor system, do not listen at excessive sound
pressure levels. Most national safety and health administrations have established
guidelines for maximum time being exposed to sound pressure levels before hearing
damage occurs.
85 dB(A) SPL at 8 hours
88 dB(A) SPL at 4 hours
91 dB(A) SPL at 2 hours
94 dB(A) SPL at 1 hour
97 dB(A) SPL at 30 minutes
100 dB(A) SPL at 15 minutes
120 dB(A) SPL — avoid or hearing damage may occur
In live settings it is difcult to make exact measurements of Sound Pressure Levels
(SPL) present at the eardrum, which is affected not only by the in-ear monitor
volume, but by ambient sound on the stage and other factors.
To protect your ears from hearing damage:
• Use the in-ear monitor system at the lowest volume possible; turn up the volume
only enough to hear.
• Be aware that ringing in your ears may indicate that the volume is set too high.
• Have your ears examined regularly by an audiologist.
• If wax builds up in your ears, stop using the in-ear monitor system until you have
seen an audiologist.
• To avoid infections, use an antiseptic to wipe the earphones before and
after using the system.
• Stop using the earphones if you experience ear discomfort or infection.
