Warnings

Failure to follow these recommendations may severely
reduce the amount of hearing protection provided by
the earplugs.

• Earplugs comply with EN-352 standard
of measurement.

• Eartips t ear canal diameters of 6-13 mm.
See Eartip section for details.

• Earplugs must be tted, adjusted and maintained

to the manufacturer’s instructions to achieve the
expected attenuation and hearing protection.

• Use earplugs at all times in noisy surroundings.

• Make certain that the earplugs provide adequate

protection for the noisy environment.

• Earplugs are reusable. Regularly inspect the earplugs

to assure their continued serviceability.

• Connecting cord should not be used where there
is a risk that the connecting cord can be caught up

during use.

Warnings (continued)

• This product may be adversely affected by certain

chemical substances. Further information should
be sought from the manufacturer.

• This earplug is provided with level-dependent

attenuation. The wearer should check correct

operation before use. If distortion or failure
is detected, the wearer should refer to the
manufacturer’s advice for maintenance and
replacement of the battery.

Warning: The output of the level-dependent

circuit of the hearing protector may exceed the
daily limit sound level.

• To determine if the device is working, insert a

battery, cup the device in your hand and listen for
acoustic feedback (squeal). If feedback is present,
the battery is working.

Battery Insertion

5

Selecting an eartip:

The eartip that is most comfortable is the likely choice,
but it must seal well for maximum protection.

When changing eartips, push the neck cord against
the body of the device; then secure the eartip
completely on the stem.

The battery must be installed correctly or the device will
not work. The battery door will not close if the battery is

upside down.

• Remove the tab on the battery before

inserting it in the device.

• Open the battery door and insert

the battery with the at side facing up.

• Be sure the + on the battery is on the

same side as the + on the door.

Insertion & Removal

6

Insertion

• Make sure the eartip is clean.

• Pull the ear up and out while
inserting (Fig. 1).

• Twist and push gently until the

eartip seals in the ear canal.

(Fig. 2).

• When using 3-ange eartips,

moistening may ease insertion.

• When using foam eartips: Roll

down or compress foam before
inserting. Hold the eartip in
place for about 5 seconds
while foam expands to create
a tight seal in the ear canal

(Fig. 3).

• When using glider eartips

no compression is needed;
simply push into ear.

Removal

• Remove with a slow

twisting

motion for all eartips.

• After removal, place earplugs

in a clean, protective case.

Operation

7

ON/OFF

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.

Two Modes of Protection

Natural Hearing with 15-dB Sound Reduction

(switch toward battery door)

• Natural hearing until sound exceeds safe levels

• Automatic 15-dB protection when hearing is at risk

• Impact noise protection

Enhanced Hearing with 9-dB Sound Reduction

(switch away from battery door)

• 6-dB gain for soft sounds

• Automatic 9-dB protection when hearing is at risk

• Impact noise protection

Closed = ON

Battery Life

Low Battery Warning

8

Warning: Performance may deteriorate with battery

usage. The typical period of continuous use that can
be expected from the earplug battery is 300 hours.

Battery life is estimated at 2-3 weeks for continuous
operation. Each device uses one #312 zinc-air battery.
It is not necessary to recycle these batteries. Zinc-air

batteries are not harmful to the environment and
can be discarded in the trash. Keep batteries out of
the reach of children.

Recommendation: Carry spare batteries in case
a battery reaches end of life while using a device.

LOBAT

™

: A ticking sound becomes faster and louder,
like the sound of a motorboat when the battery is
about to die. After the warning sound rst becomes
audible, it may be a few hours before the battery

dies. Performance and protection do not change

while LOBAT

™

is sounding.

Changing Filters

9

Earplugs have special lters that enhance sound
quality and prevent ear wax from entering the
devices. A lter should be changed if the volume
decreases or sound quality declines.

ACCU•Filter™ Removal

Note: Use the tool to remove the filter.

ACCU•Filter™ Replacement

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

1. Remove eartip.

1. Insert a new
filter.

2. Insert tool into
the filter.

2. Press gently
against a hard
surface to secure
the filter in place.

3. Remove the filter.

3. Re-attach
the eartip.
