Peltor MT53H79A-77 Manual De Instrucciones página 7

CONGRATULATIONS ON AN EXCELLENT CHOICE!
This Peltor headset has been tested and approved according to PPE directive 89/
686/EEC and EMC directive 89/336/EEC, which means that it meets the demands
for CE marking. Read these instructions carefully to ensure the best possible benefit
from your Peltor product.
A) STANDARD FLEX HEADSET
Properties
1a. Extra broad headband (MT53H79A-77) with soft padding for ideal comfort
throughout the working day.
1b. Helmet attachment (MT53H79P3E-77) for all regular helmet types. Peltor's
helmet, visor and rain protector fit this helmet attachment.
2. Individually sprung headband wires of stainless steel provide an even distribu-
tion of pressure around the ears. Steel headband wires maintain their resilience
better than regular plastic headbands through a wide range of temperatures.
3. Low, two-point fasteners and easy height adjustment with no protruding parts.
4. Soft, wide foam/fluid-filled ear cushions with built-in pressure-relief canals for
low pressure, effective sealing and ideal comfort.
5. Specially selected earphones, which provide excellent sound reproduction
even in noisy environments.
6. Socket terminal for equipment connector cord.
7. Electret microphone with high noise suppression. Easy to replace because they
use an external connecter.
8. PTT built into the shell.

C) ASSEMBLY/CONFIGURATION
Headband A (Fig. C)
(C:1) Slide out the cups. Place the headset over your ears so that the ear cushions
fit snugly.
(C:2) Adjust the cups to a snug, comfortable fit by pulling the cup up or down while
pressing the headband down.
(C:3) The headband should lie across the top of the head.
P3E Helmet attachment (Fig. E)
(E:1) Snap the helmet attachment into the slot on the helmet.
The cups can be set in three positions:
Working position (E:2), ventilation position (E:3) and parked position (E:4).
When in use, the cups must be placed in working position: Press the headband wires
inwards until you hear a click on both sides. Ensure that the shell and the headband
wires in working mode do not press against the lining or edge of the helmet so that
noise leakage can occur.
Note: During long hours of use, the attenuating foam in the shells can become damp,
which may cause damage to the electric circuits.
Make sure to remove the hygiene kit and let the foam dry by placing the headset in a
position that allows ventilation (E:5).
Do not store the hearing protector tightly fitted to the hardhat (E:6).
