LF Trigger FeaturesLF Trigger Features

LF Trigger permits to switch ON and OFF your WUS in order to preserve battery life duration.

ON BUTTON = LF Wake-up

Push ON button (more than 20 sec) to wake up your WUS and activate the permanent transmission (5s on parking mode and 1s when driving > 20km/h). The Paddock survey or LCD display will display data as soon as it receives the desired frame.

FORCE BUTTON :

Enable you to learn ID on display by sending an LF request to the sensor

OFF BUTTON : LF Sleep

Push OFF button (more than 20 sec) to switch off (no RF transmission) your WUS. At this time, the pressure and temperature information will not be available on the paddock survey or LCD display after more than 20 seconds.
