OPERATION (CONT.)
Fitting the Hearing Protection
Place the headband over your head ensuring the headband follows
the contour of the top of your head.
Guide one ear cushion over your left ear and one over your right ear.
Slowly allow the headband to draw each cushion over your ears
ensuring both cushions form comfortable cupped seals over each ear.
If the ear cushions do not sit centrally over both ears they should be
repositioned by moving them up or down the slot on the headband
until both ear cushions are centered and sit comfortably and tightly
over both ears.
If possible use an available noise source to check the seal formed
over both ears and if required slightly re-adjust the ear cushions to
achieve optimum hearing protection.
Installing/Removing the Batteries
The batteries fit within the ear piece which has the On/Off Switch.
• Lift the ear cushion from the ear piece using a coin or similar flat
object in the slot provided.
• Remove the ear cushion and foam.
• Install new AA batteries, one into each separate cavity. Ensure you
insert the negative and positive ends of the batteries as indicated
within the cavity.
• Reassemble the foam and ear cushion back to the ear piece.
Note:
Requires (2) AA batteries (not included). Always replace both
batteries at once, failure to do so may affect the performance of the
hearing protection.
