GENERAL FITTING INSTRUCTIONS
Before following the fi tting instructions below, brush excess hair aside and remove any ear jewellery that could aff ect acoustic seal. The cushions should form a snug
fi t 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)
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.
A 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.
Helmet attachment (Illustration B)
B 1: Left and Right cups. The cups are designed to be used either on the left hand side or on the right hand side of the helmet. The cup marked with a letter L
must be put on the left hand side of the helmet and the cup marked with a letter R must be put on the right hand side of the helmet. Make sure to put them the
right way round.
B 2-3: Fitting the cups. Pull the ear cup down to the bottom of the yolk and lift the blade until the spring clicks up (B2). Push the attachment blade fi rmly into
the slot on the side of the helmet until it clicks into place (B3). Release the head harness from the rear of the helmet and place the lead from the cups above the
harness' attachment and replace the harness. Make sure the lead is not tangled.
B 4: Working Position. Adjust the cups until they are comfortable. Make sure that the cushions seal tightly around the ears.
NOTE! In noisy environments, the ear-muff s must be worn in the working position at all times.
B 5: Stand-by position. Pull the ear-muff away from the ear until it locks into the stand-by position.
B 6: Parking Position. First lift the cups to the stand-by position, and then rotate them up to the next fi xed position. In this position, the cushion does not get
damaged or dirty and the cups can dry out on the inside.
NOTE: Do not press the cups onto the helmet shell as this will lock the spring in the ear-muff arm, and damage the attachment slots on the
side of the helmet.
B 7: Storage Position. When the helmet is not in use, lower the ear-muff s and press them inward.
Battery replacement (Illustration E)
The product must be equipped with two standard alkaline batteries, 1.5 V AA/LR6. The use of rechargeable batteries such as NiMH 1.2 V or NiCd 1.2 V will
signifi cantly reduce the operating time. The battery compartment is located in the left cup. To install new batteries, remove the lid (E1) and insert the batteries.
Make sure that the + and – poles are correctly aligned (E2). Replace the lid.
The product should be turned off during battery replacement.
