OPERATIONAL CRITICAL WIRELESS
EARPIECE PTT PMLN7851
Congratulations on your new Motorola Solutions
Operation Critical Wireless (OCW) Earpiece PTT!
This earpiece device is designed to allow you the
convenience of Bluetooth technology by enabling you
to comfortably wear it for long periods of time.
Furthermore, the Bluetooth earpiece is exclusively
designed with PTT functionality for business radio
applications and optimized to work with Motorola
Solutions two-way radio and Motorola Solutions
applications.
This user guide contains the operation and pairing
instructions of the earpiece. Before getting started,
please make sure you read and understand the RF
and Acoustic Safety sections, which contain very
important information about this product.
FOREWORD
Product Safety and RF Exposure Compliance
Before using this product, read the
operating instructions for safe usage
contained in the RF Energy Exposure and
Product Safety Guide enclosed with your
radio.
ATTENTION!
The radio is restricted to occupational use only to
satisfy ICNIRP/FCC RF energy exposure
requirements. Before using this product, read the RF
energy awareness information and operating
instructions in the RF Energy Exposure and Product
Safety Guide booklet enclosed with your radio
(Motorola Solutions Publication part number
6881095C98 (US) or 6864117B25 (EMEA)) to ensure
compliance with RF energy exposure limits. This
device complies with part 15 of the FCC Rules and
Industry Canada license-exempt RSS standard (s).
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. (3) Changes or modifications
made to the device, not expressly approved by
Motorola Solutions, could void the authority of
the user to operate this device.
Battery Information:
Battery is shipped with a nominal charge between
30% and 50%. Battery should be stored between
-10 °C (14 °F) and 30 °C (86 °F) to minimize
permanent capacity loss.
Caution: Storing your fully charged accessory in
high-temperature conditions may
permanently reduce the life of the internal
battery.
Note: The battery is not a user replaceable part.
Important Information:
• Do not charge your accessory in temperatures
below 0 °C (32 °F) or above 45 °C (113 °F). Do not
store your accessory in direct sunlight or where
expected temperatures can exceed this range such
as inside a parked car.
• Storing your fully charged accessory in
high-temperature conditions may permanently
reduce the life of the internal battery.
• Battery life may temporarily shorten in low
temperature conditions.
ACOUSTIC SAFETY
Exposure to loud noises from any source for
extended periods of time may temporarily or
permanently affect your hearing. The louder the
radio's volume, the less time is required before your
hearing could be affected. Hearing damage from loud
noise is sometimes undetectable at first and can have
a cumulative effect.
To protect your hearing:
• Use the lowest volume necessary to do your job.
• Turn up the volume only if you are in noisy
surroundings.
• Turn down the volume before adding headset or
earpiece.
• Limit the amount of time you use headsets or
earpieces at high volume.
GETTING STARTED
Before you start, make sure that the earpiece is fully
charged. Recommended charging time is two (2)
hours.

Solutions LMR radios. After device connects to a
radio, pressing PTT button enables one-way
communication such that voice taken from local
microphone can be transmitted to the remote radio.
Releasing the PTT button puts the device back to
(default) stand-by mode and audio transmitted from
the remote radio can be heard from the local speaker.
LTE mo de
When device connects to a smartphone in LTE mode,
it can function as a standard Bluetooth headset that
supports phone conversation and stereo music
listening. In addition, if Motorola Solutions APP is
running (on either iOS or Android platform), it can
work as a PTT device similar to radio use case. The
following table shows user interfaces with different
functions.
