TURNING ON AND OFF
The Transmitter is always in a permanent sleep state.
It is only ON when a button is being pressed and does
not need to be turned off by the user.
Turning the Collar Unit ON:
Press and hold the ON/OFF button. The SmartLED
Indicator will light solid red for one second. Release
the button when the SmartLED begins to flash. The
unit is now ON, and the SmartLED will flash
approximately every two seconds.
Turning the Collar Unit OFF:
Press and hold the ON/OFF button. The SmartLED
Indicator will light solid red for one second. Release
the button when the SmartLED begins to flash. The
unit is now OFF, and the SmartLED will no longer
flash.
NOTE
If the SmartLED on the Transmitter flashes red rapidly after
any button is pressed, or if the SmartLED on the Collar Unit
double-flashes red every other second while ON, the unit
will need to be recharged. If this happens soon after a full
charging session, the rechargeable batteries may need to
be replaced.
