Install unit

In order to use the Confidea WDU, first install the battery and microphone. For instructions, see "Battery pack" on page 1 and "Microphones" on page 1. Disconnect the battery to avoid unwanted operation of the unit. Keep the devices in a clean and dry area.

Startup and shutdown of delegate unit

To start up the delegate units simply press the microphone button for a few seconds until the LEDs start to blink. When units are connected to a WCAP that is switched off , the units will go into sleep mode after about 2 minutes, if no connection with another WCAP could be established.

If the delegate units are activated they will continue to search for a connection with a WCAP, so if no connection with a WCAP could be established , the delegate units will remain on! To switch off the delegate units or to deactivate the automatic sleep mode, remove the battery of the unit.
