PELTOR ALERT – ACTIVE-VOLUME
HEARING PROTECTOR RADIO
The Peltor ALERT active-volume hearing protector radio,
M2RX7*, provides comfortable, effective protection from
harmful noise. At the same time, it provides added safety
because its active volume function attenuates loud noises
while amplifying weak ones. And the AM/FM stereo radio
receiver provides extra working pleasure. The Peltor ALERT
is ideal for professionals and private individuals alike – per-
fect for mowing the lawn or practicing on the target range.
For complete two-way communication, the Peltor ALERT
also comes in a headset model.
Read these instructions carefully to ensure the best pos-
sible benefit from your Peltor ALERT.

Headband:
(B:1) Slide out the cups. Place them over your ears so that
the ear cushions fit snugly.
(B:2) Adjust the height of the cups to a snug, comfortable
fit by pulling the cup up or down while pressing the
headband down.
(B:3) The headband should lie across the top of the
head.
Helmet attachment:
Snap the helmet attachment into the slot on the helmet
(see fig. B:4). When in use, you must press the headband
wires inwards until you hear a click on both sides, from
ventilation to working mode. Ensure that the cup and the
headband wires in working mode do not press on the edge
of the helmet so that noise leakage can occur.
Note: The ear cups can be set in three positions: Work-
ing position (B:5), ventilation position (B:6) and parked
position (B:7).
Important! For the best protection, brush aside hair around
the ears so the ear cushions fit snugly against the head.
Spectacle frames should be as thin as possible and fit
close to the head.

tions in this manual.
