Instructions For Use

ON/OFF

HD•15 earplugs turn on and off by opening and closing the battery door.Note: It is not necessary to remove the battery as long as the door is open wide enough to disable the circuit.

Dual-Mode Switch

LO position

• Allows natural hearing until noise exceeds safe levels
• Automatic high-fidelity 15-dB sound reduction for continuous loud noise
• Maximum protection from blasts

        (switch toward device) 

HI position

• Amplifies soft sounds and conversational speech
• Maximum protection from blasts

        (switch away from device)

Insertion

Important: Sound quality and noise isolation depend on a good eartip seal.

• Carefully insert the earplug while pulling up and out on the back of the ear.
• Twist and push gently until the eartip seals in the ear canal.
• 3-flange eartip: Moistening eases insertion.
• Foam eartip: Roll down or compress foam eartip before inserting. Hold the eartip in place for about 5 seconds while the foam expands to create a tight seal in the ear canal.
• Glider eartip: Simply push into ear canal.

Removal

Remove the device with a slow twisting motion. Open jaw slightly to equalize pressure, because suction can occur when the eartip is removed.

Care

• Do not expose to extreme temperatures.
• Avoid dropping and strong impact.
• Leave eartip on the earplug for shock protection.
• Clean or replace eartips prior to use by others.

Cleaning and Replacing Eartips

Over time eartips may lose their elasticity. For best performance and retention, replace 3-flange eartips every 3-6 months. Replace foam and glider eartips regularly.

To clean the 3-flange eartips:

• Remove the eartip from the earplug.
• Clean with water and mild soap.
• Dry the eartip before placing it back on the earplug.

Changing the Filter

The earpiece in the GSP•15 earplugs have a special filter that smoothes the frequency response and prevents earwax from entering the earphone. The filter is located at the end of the earplug and is visible when the eartip is removed. Change the filter if loudness decreases or the sound quality declines.

Note: Filters are not reusable.

Removal

Note: Use the tool to remove the filter.

Replacement

Note: Do not use the tool to replace the filter.
