4.3. CARRIER DEVICES
These earmuffs should be fitted to and used only with the
carrier devices listed in table H. These earmuffs were tested
in combination with the carrier devices listed in table H, 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 BATTERIES
(Figure F)
Make sure you have read and understood the contents of
Chapter 2. Safety before replacing the battery/batteries.
F:1. Loosen the screw holding the battery lid using a screw
driver. Turn the screw counter clockwise.
F:2. Tilt the lid top outwards (1). Pull the lid downwards (2) in
order to remove it from the headset.
F:3. Insert or replace the batteries. Make sure the polarity
corresponds to the markings. Install the lid on the headset
and tighten the screw.
Low battery level is indicated by a voice message: “battery
low” , repeated every five minutes. If the batteries are not
replaced, a “battery empty” warning will eventually be heard.
The unit will then switch off automatically.
NOTE: Performance may deteriorate as the batteries get low.
7. FITTING INSTRUCTIONS
7.1. GENERAL
Inspect the hearing protector before each use. If damaged,
select an undamaged hearing protector or avoid the noisy
environment.
NOTE: Brush aside hair around your ears so the ear cushions
(A:5) fit snugly.
Spectacle frames should be as thin as possible and fit close
to the head to minimise acoustic leakage.
