Fitting Instructions - 3M PELTOR WS LiteCom Plus Manual Del Usuario

• Although hearing protectors can be recommended for
protection against the harmful effects of impulsive noise, the
Noise Reduction Rating (NRR) is based on the attenuation of
continuous noise and may not be an accurate indicator of the
protection attainable against impulse noise, such as gunfire.
• In Canada, users of hard hats combined with earmuffs must
refer to CSA Standard Z94.1 on industrial protective headwear.
This portable device with its antenna complies with FCC/IC RF
Exposure limits for general population / uncontrolled exposure.
The antenna used for this device must not be co-located or
operating in conjunction with any other antenna or transmitter.
Changes or modifications to the equipment not expressly
approved by the party responsible for compliance could void
the user's authority to operate the equipment.
• Operating temperature range: –20°C (–4 °F) to 55 °C
(131 °F)
• Storage temperature range: –20 °C (–4 °F) to 55 °C
(131 °F)
• Weight of hearing protector: 435–470 g
LABORATORY ATTENUATION
The attenuation rating NNR was obtained with the device
powered off.
Explanation of attenuation tables:
USA Standard ANSI S3.19-1974
3M strongly recommends individual fit testing of hearing
protectors. If the NRR or SNR is used to estimate typical
workplace protection, 3M recommends that the noise reduction
value be reduced by 50% or in accordance with applicable
regulations.
A:1 Frequency (Hz)
A:2 Mean Attenuation (dB)
A:3 Standard Deviation (dB)
The level of noise entering a person's ear, when hearing
protector is worn as directed, is closely approximated by the
difference between the A-weighted environmental noise level
and the NRR.
Example
1. The environmental noise level as measured at the ear is
92 dBA.
2. The NRR is 27 decibels (dB).
3. The level of noise entering the ear is approximately equal
to 65 dB(A).
When selecting accessories to respiratory personal protective
equipment, such as hard hat mounted hearing protection,
please consult the NIOSH approval label or consult 3M
Technical Services for approved configurations.

FITTING INSTRUCTIONS

Headband
B:1 Slide out the cups and tilt the top of the shell out, as the
cable must be on the outside of the headband.
B:2 Adjust the height of the cups by sliding them up or down
while holding the headband in place.
B:3 The headband should be positioned across the top of the
head as shown and should support the weight of the headset.
Neckband
B:4 Place the cups in position over the ears.
B:5 Keep the cups in position, place the head strap on the top
of your head and lock it tight in position.
B:6 The head strap should be positioned across the top of
your head and should support the weight of the headset.
Helmet Attachment
B:7 Insert the helmet attachment in the slot on the helmet and
snap it into place (B:8).
B:9 Work mode: Press the headband wires inwards until you
hear a click on both sides. Make sure that the cups and the
headband wires do not press on the edge of the helmet when
in work mode as this could reduce the noise attenuation of
