GENERAL FITTING INSTRUCTIONS
Before following the fitting instructions below, brush excess hair aside and remove any ear jewellery that could affect
acoustic seal. The cushions should form a snug fit against the head with no interference of the seal by any objects e.g.
respirator headbands or spectacles arms, and that the cups completely enclose the ears.
Headband version (Illustration A)
1. Make sure to put the headband the right way round. The inside of the headband is marked with a letter L on the
left hand side and a letter R on the right hand side. Ensure that the headband is positioned correctly (see Fig. A1).
2. With the headband over the head, adjust the height of the cups by sliding them up or down, so they completely
enclose the ears (see Fig. A2).
Helmet mounted version (Illustration B)
These hearing protectors should be fitted to, and used only with, the following industrial safety helmets (see table 2):
1. Ensure that the cups are mounted on the correct side of the helmet. The cup marked with L must be put on the left
hand side of the helmet and the cup marked with R must be put on the right hand side of the helmet (see Fig. B1).
2. Pull the ear cup down the fork as far as possible and put the cup in stand-by-position (see Fig. B2).
3. Push the attachment clip firmly into the slot on the side of the helmet until it clicks into place (see Fig. B3).
4. For the working position, press the cups toward the ears until they click into place. Adjust the height of the cups by
sliding them up or down so they completely enclose the ears (see Fig. B4).
5. Stand-by position: Pull the cups away from the ears until they lock into the stand-by position (see Fig. B5).
6. Parking Position: From the stand-by position, rotate the cups to the rear of the helmet until they click into place. In
this position, the cushions do not get damaged or dirty and the cups can dry (see Fig. B6). NOTE: Do not press the
cups onto the helmet shell as this will lock the spring in the cup arm, and damage the attachment slots on the side
of the helmet.
7. Storage Position: When the helmet is not in use, lower the cups and push them inwards until they click into place
(see Fig. B7).
WARNING!
Headband/helmet mounted hearing protectors complying with EN 352-1/EN 352-3 are of 'medium size range', 'small size
range' or 'large size range'. 'Medium size range' Headband/helmet mounted will fit the majority of wearers. 'Small size
range' or 'large size range' headband/helmet mounted hearing protectors are designed to fit wearers for whom 'medium
size range' headband/helmet mounted hearing protectors are not suitable. For approved sizes, please refer to table 2
(headband and helmet mounted).
These hearing protectors should be fitted to, and used only with, the industrial safety helmets listed in Table 2, which
also shows the applicable size range and correct adaptor type. Additional helmets may have been approved following
publication of these instructions. Please contact your distributor for further information.
STORAGE
When the hearing protector is not in use, store it in such a way that the headband is not stretched and the cushions are
not compressed. Keep the hearing protectors dry and clean, store them at normal room temperature and do not place
them in direct sunlight.

MAINTENANCE

Clean and disinfect the cups, cushions and inserts with mild soap and water only. This product may be adversely affected
by certain chemical substances. Further information should be sought from the manufacturer. Hearing protectors and
cushions in particular may deteriorate with use and should be examined at frequent intervals for cracking and leakage, for
example at the start of every working shift.
HYGIENE KITS (Illustration C)
The cushions and inserts are replaceable. Always replace worn or damaged parts. Remove the cushion by pulling it
straight out (C1). Replace the old cushion and insert with new ones from the hygiene kit (C2). Use only hygiene kits from
the manufacturer, consisting of one pair of cushions and one pair of inserts. It is recommended that the hygiene kit should
be replaced at least twice a year for standard use to ensure that the noise attenuation performances are maintained.
The fitting of hygiene covers to the cushions may affect the acoustic performance of the hearing protectors. For order
reference, please refer to Table 3.
