StorageConditions
The SDP and SM series earmuffs should be stored at room temperature (between 15C and 25C).
If storing for long periods (greater than 1 month) discharge the unit for at least 8 hours before storing
for maximum battery life.
Cushion Replacement
The SDP and SM series earmuffs contain replaceable cushions. Cushions should be inspected regularly
for signs of damage or wear and replaced as necessary. Contact your Sensear reseller or distributor for
replacement hygiene kits (P/N SMHK0000). Cushions can be removed simply by gripping the cushion
and pulling firmly to unclip from the baseplate. Replacement cushions may be pushed into clips around
the baseplate.
The SDP has been tested and approved according to
the methods described in the En352 series of standards.

muff with Bluetooth module), and the SM1x SR – (Ear-muff with Bluetooth module as well as FM
transmit and receive capabilities), comply with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(i) This device may not cause harmful interference
(ii) This device must accept any interference received, including interference that may cause
undesired operation.
WARNING: Any changes or modications not expressively approved by Sensear Pty. Ltd. could
void the user’s authority to operate this equipment.
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 into an outlet on a circuit different from that to which the receiver is
connected.
CONSULT THE DEALER OR AN EXPERIENCED RADIO/TV TECHNICIAN FOR HELP.
NRR AND SLC80
The SM1, SM1x and SM1x SR models have been certied to European Standards EN352-
1:2002, ANSI S12.6-1997 and AS/NZS 1270-2002. The following passive attenuation ratings were
observed;

OVERVIEW
The Sensear SM1, SM1x and SM1x SR models hearing defense systems are state-of-the-art hearing
protectors. The systems have sophisticated electronics and algorithms to enhance speech in noisy
environments. As a result, Sensear SM1, SM1x and SM1x SR users do not need to remove their
hearing protection to hear speech in noisy environments.
In addition, the SM1x SR units incorporate FM short range connectivity, Bluetooth technology,
external audio pass-through and two-way radio connectivity. This enables users to communicate
to other SM1x SR users wirelessly, effectively answer a phone call, listen to an MP3 player or use
a two-way radio whilst wearing their hearing protection.
The SM1x unit is functionally identical to the SM1x SR in every respect, with the exception of the
FM short range connectivity. The SM1x communication features include Bluetooth technology,
external audio pass-through, face-to-face and two-way radio connectivity.
The SM1 unit is functionally identical to the SM1x in every respect, with the exception of the
Bluetooth connectivity function. The SM1 communication features include face-to-face and two-
way radio connectivity.
The SM1 Ultra and SM1x (SR) Ultra models include a noise cancelling boom microphone for extreme
noise environments. Standard models may be upgraded by purchasing the Boom microphone
upgrade kit.
The SM1, SM1x and SM1x SR are available in over-the-head headband or helmet mount models.
Helmet mount adaptors are available for a wide range of helmets. See section Helmet Mounts.
The basis of the SM1, SM1x and SM1x SR units consists of advanced signal processing algorithms
that process sound. The output of these algorithms is referred to as the SENS processed sound. In
the SENS processed sound, the speech of nearby speakers is enhanced while at the same time,
the surrounding noise is suppressed. The SENS processed sound is the sound delivered to the
SM1, SM1x and SM1x SR users.
Noise reduction will be adversely affected by anything that impairs the seal of the earmuff cushions
against the head, such as thick spectacle frames, balaclavas, etc. Cushions may deteriorate with
use and should be renewed regularly.
