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 fit ear canal diameters of 6-13 mm.
See Eartip section for details.
• Earplugs must be fitted, 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.

Warning (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.

In ertion & Removal
Ins rtion
• 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-flange eartips,
moistening may ease insertion.
• When using foam eartip: Roll
down or compress foam eartip
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 a glider eartip
no compression is needed;
simply push into ear.
R moval
• Remove with a slow
twisting
motion for all eartips.
• After removal, place earplugs
in a clean, protective case.

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 first becomes
audible, it may be a few hours before the battery
dies. Performance and protection do not change
while LOBAT™is sounding.
Low Battery Warning
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 this battery. Zinc-air
batteries are not harmful to the environment and
can be discarded in the trash. eep batteries out of
the reach of children.
R comm ndation: Carry spare batteries in case
batteries reach end of life during use.
