USE
1. Make sure that there is no hair under the sealing rings.
Remove earrings that prevent the sealing rings from
sealing tightly.
2. Place the headband over your head and adjust the
cups so that they cover your ears.
3. Move the cups up or down in the headband to adjust
them, so that they fit firmly and comfortably and seal
round the ears.
4. Check the fit by talking loudly. Your voice should sound
muffled. Ambient noise should sound weaker than
without the ear defenders.
5. Check that the cups’ sealing rings sit firmly against
your head and around your ears.
FIG. 1
NOTE:
Pull hair away from your ears and use glasses with
thin frames to minimise the admission of noise. Never
attempt to change the shape of the headband.
