Installation
The W400(EX) device has been designed to be worn by the user. The
device can be worn over clothing by passing the silicone rubber antenna
lead around the neck and then connecting the end terminal of the antenna
in its support.
The device can also be installed directly on a self-inflating lifejacket by
passing a Velcro strip through the rear fixing stirrup and attaching the
antenna along the lifejacket, again behind the user's neck. For this type of
installation please consult the lifejacket manufacturer.

the 'ARMED' position.
Press the pushbutton (2) inwards to release the safety lock. Then, keeping
the pushbutton pressed, rotate the knob anticlockwise until it reaches the
'ARMED' position, then release the pushbutton (2).
