WamBlee W4 Series Manual

Some questions and answer about MSLD (MOB - Man Over
Are MOB devices EPIRBs (Emergency Position Indicator Radio Beacon) or PLBs
(Personal Locator Beacon)?
No, they aren't. An EPIRB or a PLB operate through a satellite network which can detect a
radio signal emitted at 406 MHz, efect a triangulation and determine (with quite good
approximation) the position of the buoy. These devices operate at diferent frequencies
according to the MOB model and they are able to alert the rescues in case of emergency.

Why should I buy a MSLD (MOB) instead of an EPIRB buoy?

The two products are diferent and have diferent functions. If you need to have an
emergency device that is able to signal a serious damage of the vessel the EPIRB is the
suitable device. If you need to have a security system on-board, for the vessel crew, that
must activate in case of man over-board, the MSLDs (MOB) are the right choice.

How do they work?

The Wamblee devices of W4XX series start when they come into contact with water (fresh
or salt) for a continuous and superior time of 5 seconds (or in alternative it can be
operated manually by the frontal push-button). Once activated, the devices generate a
diferent radio signal according to the MOB model
Board) device

W400 model

The W400 device emits a radio signal at 121.5 MHz with a power of
100mW in AM (Amplitude Modulation). For a correct reception of the
signal, on board of the vessel it must be installed a VHF receiver
capable of receiving the emergency signal.
The unit has a blinking flash for night-time localization.
