Pettec Antibark Vibra Trainer 2.0 Bedienungsanleitung Seite 21

The Antibark Vibra Trainer 2.0 is equipped with a safety feature
which puts it into sleep mode after the sixth signal is triggered within
one minute (either a tone or vibration signal).
This sleep mode lasts for a full minute in which neither a tone nor
a vibration signal can be triggered. During this time an »E«
flashes in blue on the LED display. As soon as the signal on the LED
display disappears, the Antibark Vibra Trainer 2.0 returns to regular
operation. But pressing any button will bring the device out of sleep
mode and back into normal operation.
To turn off the Antibark Vibra Trainer 2.0, hold the power button for
several seconds until you hear a double beep.
