Product Safety and RF Exposure Compliance:
This product is designed to be used in isolation or in conjunction with a
two-way radio. Before using this product with a two-way radio, read
the operating instructions for safe usage contained in the Product Safety
and RF Exposure booklet enclosed with the two-way radio.
FCC COMPLIANCE STATEMENT
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment intoan outlet on a circuit different
from that to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician
for help
This device complies with part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation

TWO-WAY RADIO INPUT (EN352-6)
The electrical input level for which the mean plus one standard
deviation is A-weighted diffused-field related sound pressure level is
equal to 82 dB(A) is an RMS voltage U = 108mV.
SIZE RANGES
WARNING Earmuffs complying with EN352-1 are of ‘small size
range’, ‘Medium size range’ or‘large size range’. ‘Medium size range’
earmuffs will fit most wearers. ‘Small size range’ or ‘large size range’
earmuffs are designed to fit wearers for whom ‘medium size range’
earmuffs are not suitable. The SM1P Ex headband, SM1P Ex
behind-the-neck, and SM1P Ex helmet adapters may be adjusted for
small, medium, or large size.

MAINTENANCE AND CLEANING
The headset is an active hearing protector that allows audible contact with
your surroundings while providing protection from harmful noise.
It is recommended that the headset is fitted, adjusted, and maintained in
accordance with these instructions. This headset should always be worn in noisy
surroundings. The headset should be regularly inspected for serviceability.
Warning:
• If these instructions are not followed the protection of the
headset will be severely impaired.
• Noise reduction will be adversely affected by anything that
impairs the seal of the earmuff cushions against the head,
such as thick spectacle frames and balaclavas
• The reported attenuation will be obtained only if the headset
is in good condition and worn as directed (Refer to AS/NZS
1269.3 for guidance).
• This product should not be used where there is a risk that the
connecting cord could be caught up during use.
• This product is provided with level-dependent in-ear audio
playback. The wearer should check correct operation before
use. If distortion, or failure is detected. The wearer should
refer to the manufacturer’s advice for maintenance and/or
replacement.
Warning:
• Performance may deteriorate with battery usage. The typical
period of continuous use that can be expected from the
headset will depend on the two-way radio battery.
• The output of the level-dependent circuit of this hearing
protector may exceed the daily limit sound level. This limit
can be adjusted with a Sensear programming tablet.
• This headsethas been tested and approved according to the
methods described in the EN352series of standards.
