4.3. CARRIER DEVICES
These earmuffs should be fitted to and used only with the
carrier devices listed in Table C. These earmuffs were tested
in combination with the carrier devices listed in Table C, and
may give different levels of protection if fitted to different
carrier devices.

6. SETUP
6.1. GENERAL
The following points covers the main actions to make the
product ready for operation.
6.2. REMOVE/INSTALL BATTERY/BATTERIES
Make sure you have read and understood the contents of
Chapter 2 "SAFETY", before replacing the battery/batteries.
Use a screwdriver or the like to open the cover by turning it
counterclockwise.
Insert or replace the batteries. Make sure the polarity
corresponds to the markings.
7. FITTING INSTRUCTIONS
Inspect the hearing protector before each use. If damaged,
select an undamaged hearing protector or avoid the noisy
environment.
7.1. HEADBAND
(Figure E:1 - E:3)
E:1 Slide out the cups and tilt the top of the shell out, as the
cable must be on the outside of the headband.
E:2 Adjust the height of the cups by sliding them up or down
while holding the headband in place.
E:3 The headband should be positioned across the top of the
head as shown and should support the weight of the headset.
7.2. CARRIER ATTACHMENT
(Figure E:4 - E:8)
E:4 Insert the carrier attachment in the slot on the carrier and
snap it into place (E:5).
E:6 Work mode: Press the headband wires inwards until you
hear a click on both sides. Make sure that the cups and the
headband wires do not press on the edge of the carrier when
in work mode as this could reduce the noise attenuation of
the earmuffs.
E:7 Ventilation mode: To switch the unit from work mode to
ventilation mode, pull outward on the ear cups until you hear
a click. Avoid placing the cups against the carrier (E:8) as this
prevents ventilation.
8. OPERATING INSTRUCTIONS
8.1. POWER ON/OFF
(Figure D:8)
Turn the radio volume control knob (D:8) clockwise to power
on and counter clockwise to power off.
