WHISPER VETERINARY DEVICE
®
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.
