MusicPROelite™ High-Definition Electronic Earplugs User Manual
1' Caution Failure to follow these recommendations may severely reduce the amount of hearing protection provided by the earplugs. • At very high SPLs (above 125 dB SPL, where the limit to attenuation is the eartip itself), the foam eartips provide the most protection. • Eartips fit ear canal diameters of 6-14 mm. See eartip section for details.
,If\ Caution lcontinuedJ • Use earplugs at all times on noisy surroundings. • Earplugs are reusable. Regularly inspect the earplugs to assure their continued serviceability. Replace as recommended. See page 13. • Connecting lanyard should not be used where there is a risk that the lanyard can snag on something during use. • This product may be adversely affected by certain chemical substances. Further information should be sought from the manufacturer.

I Insertion & Removal Insertion • Pulling the ear up and out helps to properly insert the earplugs (A). • Twist and gently push the eartip until it seals in the ear canal (B). Flange eartips: Moistening may ease insertion. Foam eartips: Roll down or compress the foam eartip before inserting (C). Hold in the ear until the foam expands to create a tight seal in the ear canal. Removal • Remove the earplugs with a slow twisting motion (B).
Operation Operate the earplugs after inserting into the ears. ON/OFF To turn the earplugs ON and OFF, press and hold the switch for at least 2 seconds. When turning on, the earplugs will play an ascending series of three tones; when turning off, a descending series will be played. When initially turned ON, the device will be set to the LO operation mode.
' Operation lcontinuedJ Dual-Mode Switch Automatic Protection + Blast Protection Mode (LO) • No interference with natural hearing; soft and loud sounds are heard naturally. • Automatically delivers 15-dB of hearing protection when steady-state noise exceeds safe exposure limits. • Blast protection Enhancement + Protection Mode (HI) • Amplifies soft and conversational sounds for informed communication and increased awareness of surroundings. • No amplification of loud sounds.
Changing Eartips The eartip that is most comfortable and seals the ear is the best choice. However, the eartip must seal well and prevent feedback (whistling) to provide proper protection. A shallow seal may reduce the expected sound amplification and hearing protection. • Hold device firmly and pull on the eartip for removal. • After eartip is removed, select a new eartip from those provided in the package.
