Specifications GXLIEM Wireless In-Ear Monitor System

WARNING! USE AS LOW A VOLUME AS POSSIBLE.
PERMANENT HEARING DAMAGE CAN RESULT FROM USING THIS SYSTEM AT EXCESSIVE VOLUMES.
For the safe operation of this in-ear monitor system, do not listen to excessive sound pressure levels. Most national safety and health administrations have established guidelines for the 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 difficult 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 been 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.

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 and the receiver.

This device complies with Part 15 of the FCC Rules. Most users of CAD Audio wireless products in the United States do not need a license for operation. However, the rules for unlicensed operation state that this device must not operate in excess of 50 milliwatts and it must not cause harmful interference to other wireless devices and must accept interference received from other devices. Wireless products meeting CAD factory standards adhere to these rules. The FCC reserves the right to change these rules at any time. For more information contact the FCC at 1-888 -CALL-FCC (TTY: 1-888 -TELL-FCC) or visit the FCC’s wireless microphone website at:
