C) INSTALLATION/SETTINGS
Headband A and F (Fig. C)
(C:1) Slide out the cups. Place the headset over your ears so that
the sealing rings fit snugly.
(C:2) Adjust the height of the cups to a snug, comfortable fit by
sliding the cup up or down while holding the headband flat on
your head.
(C:3) The headband should go straight over the top of the head.
Neckband B (fig. D)
(D:1) Adjust the cups so that the ears are completely surrounded
by the ear cushions.
(D:2) Adjust the height using the headband until you have a snug,
comfortable fit.
(D:3) The headband should lie across the top of the head.
Helmet attachment P3E, P3G and P3K. (Fig. E)
(E:1) Snap the helmet attachment into the slot on the helmet.
Note: The cups can be set in three positions: Working position (E:2),
ventilation position (E:3) and parking position (E:4).
When in use, the cups must be placed in working position. Press
the wires inward until you hear a click on both sides. Make sure
that the cup and the headband wire in working position are not
pressing on the helmet lining or the edge of your hardhat so that
leakage can occur. Parking position should not be used if the cups
are damp inside after an intense period of use.
Peltor's hearing protectors fit most safety helmets in the mar-
ket

fitted as standard with snap-mount Z3E, which can be replaced with

most other safety helmets available in the market.

Replacing snap-mount Z3E with Z3G or Z3K

the snap-mount on your hearing protector.
(E:5) Unscrew the middle screw holding the Z3E snap-mount.
(E:6) Replace the snap-mount with Z3G or Z3K depending on which
type of safety helmet is being used. NOTE. Ensure the snap-mount
is turned the right way round.

IMPORTANT USER INFORMATION

100% use of a working hearing protector is the only sure protection
from hearing loss.
If you spend time in environments with more than 85 dB A-weighted
noise, you need to protect your hearing, because the hearing recep-
tors deep in your ears may be irreparably damaged. If you remove
the protectors for even a tiny portion of the time you spend in noisy
situations, you are in the danger zone.
A comfortable hearing protector designed for the specific noise
level in which it is used is the best guarantee that you will wear
the hearing protector 100% of the time, thereby ensuring protection
from permanent hearing loss.
