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 orrelocate the receiving antenna

The SM1R has level dependent facilities and the criterion levels as
defined in EN352-4 are displayed below:
Model
H M L
dB(A)
SM1R 108.6 104.6 103.4
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 SM1R Headband, SM1R Behind-the-
Neck, and SM1R 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 alwaysbeworn
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 headset has been tested and approved according to
the methods described in the EN352 series of standards.

MAINTENANCE AND STORAGE OF YOUR HEADSET
This product maybe adversely affected by certain chemical substances.
Further information should be sought from the manufacturer.
The headset contains replaceable cushions (Part # SMHK0000). Cushions are
recommended to be replaced every 3-6 months to maintain the
appropriate hearing protection that the product is certified to. Cushions
should be inspected regularly for signs ofdamageor wear. Cushions canbe
removed simply be gripping the cushion and pulling firmly to unclip
from the baseplate. Replacement cushions maybe pushed into the clips
around thebaseplate.
The headset should be stored at room temperature(between15°C/59°F and
25°C/77°F).
