WHISPER®VETERINARY DEVICE
GENERAL
DESCRIPTION
The Whisper On-Arrival system is composed of both hardware and
software components. The Whisper Veterinary device works in
conjunction with a wireless-based application that is installed and
run on a chute-side computer (tablet). Individual animal body weight
and rectal temperature are entered by the operator in the tablet and
the thoracic (i.e. chest) sound data is captured by the device and
transmitted to the tablet. A machine-learning algorithm utilizes the
information to predict the risk of BRD and provide the user with a BRD
control decision (i.e. Treat or Do Not Treat).

DEVICE
CONSTRUCTION
The device is constructed of plastic, rubber and metal materials to
ensure the protection of the electronics from adverse environmental
conditions which may include moisture, environmental temperature,
shock and vibration. Sound absorbing materials are used on the
exterior of the device to minimize interference from external noises
within the processing barn and capture a clear sound from the heart
and lungs of the animal. The device is composed of a head and a
handle that are connected by a padded shaft.
The head includes six sound sensors, a charge port, a rechargeable
lithium battery and a swivel connection. To charge the lithium battery,
plug the charger into the connector on the front of the head, behind
the door. Once the charger is connected, the LED light on the handle
will flash in 5 second intervals. When the battery is fully charged, the
flashing LED light will not rapidly blink even though the charger may
still be plugged in.

The handle contains two recording buttons for convenience, as both
buttons perform the same functions. The handle houses the LED lights
that are powered by two standard AAA alkaline type batteries that
should last a few months in normal operation and storage conditions.
NOTE
The lithium batteries are shipped from the manufacturer
in a low charge state. BEFORE FIRST USE, ensure the
battery is fully charged.

OPERATING THE
DEVICE
To turn the device on, push and release either button on the handle.
The blue LED light will come on for approximately 4 seconds and then
turn off. The head communicates with the handle wirelessly. When the
handle and the head are communicating properly, the light will blink
green in 5 seconds intervals. If the communication has been lost or the
head has gone into sleep mode, the indicator will blink blue. To “wake
up” the paddle and/or to reestablish communication to the app, press
either button on the handle.
NOTE
To ensure optimal performance, only one device should be on at
any given time. Having multiple devices on may interfere with
data transfer and create challenges with app functionality.

6
CLEANING THE
DEVICE
Maintaining the cleanliness of the device will help ensure optimal
performance, functionality and will extend the life of the equipment.
It is advised that it is cleaned at the end of each processing day.
To clean the device, use water from a hose or a faucet to rinse off the
handle, the padded shaft and the head. Use a soft rag (or your hand) to
assist in removing all dirt from the device.
NOTE
DO NOT clean the device with a high-pressure sprayer or
submerge it under water (such as in a bucket).
The charger cover on the device must be seated in the
charge connector in order to seal the connector properly
and prevent water intrusion.

CHARGING THE
DEVICE
At the end of each processing day (or anytime the system is not in
use), we recommend plugging the charger into the head to ensure
enough power is available for the next processing session. Plug the
charger into the end of the head of the device. Once connected, the
LED light on the handle will turn off and on in 5 second intervals
(rapid blinks).
