Some questions and answer about MSLD (MOB - Man Over
Board) device
Are MOB devices EPIRBs (Emergency Position Indicator Radio Beacon) or PLBs
(Personal Locator Beacon)?
No, they aren't. An EPIRB or a PLB

100 W in AM (A plitude Modulation). For a correct reception of the
signal, on board of the vessel it ust be installed a VHF receiver
capable of receiving the e ergency signal.
The unit has a blinking flash for night-ti e localization.

The W420 device e its a radio signal on AIS 1 and AIS 2 (AIS)
channels of the ariti e VHF band, with a power of 1 W. This signal
uses the AIS (Auto atic Identification Syste ) protocol and provides
the trans ission of the an's position at sea using a GPS odule with
66 channels inside the device.
The GPS odule precision is about 10 eters, and the AIS syste –
contrary to the DSC syste – forwards its position in degrees/ inutes/
seconds and fraction of seconds.
With this protocol the position error is co parable to the error of the
GPS odule (< 10 eters).
The unit has a blinking flash for night-ti e localization.

The W470 device e its a radio signal on AIS 1 and AIS 2 (AIS)
channels and a ho ing signal at 121.5 MHz, with a power of 1 W (in
AIS ode, 0.1W in Ho ing). This signal uses both AIS (Auto atic
Identification Syste ) protocol and ho ing signal for RDF (Radio
Directional Finder) and provides the trans ission of the an's position
at sea using a GPS odule with 66 channels inside the device.
This device odel co bines the perfor ance of two MOB odels:
W400 (Ho ing 121.5 Mhz) and W420 (AIS), and offers a greater
flexibility.
The unit has a blinking flash for night-ti e localization.

Has the frequency 121.5 MHz been removed from rescue monitoring system,
hasn't it?
The frequency 121.5 MHz is no longer used since February 2009 as pri ary frequency of
the EPIRB syste s anaged by Cospas-Sarsat; it is i portant to know that the 406 MHz
frequency used by satellites for the triangulation, can report a position with an

approxi ation of about 3/5 n. For this reason the EPIRBs are equipped with a second
frequency (121.5 MHz, the sa e as W400 or W470 MSLD (MOB)) that can help SAR units
to localize better the position of the accident. We choose the 121.5 MHz as the rescue
frequency of the W400 or W470 devices so that it can also be received fro the SAR units
which work in the area. For exa ple if it is not possible to deter ine the position of the
an -overboard, the aster of the ship can contact the SAR units and request an
intervention by using the 121.5 MHz frequency as search frequency.
Which is the range covered by MSLD systems?
The range covered by MSLD (MOB) syste s is indicative and depends on the technical
characteristics of the e ission of the signal; following is an indicative su ary table:
Device Range covered
W400
(121.5 MHz, 100 W)
Between shipwrecked person and vessel = ± 2n
Between shipwrecked person and aircraft = ± 10n
W420
(AIS1 and AIS2)
Between shipwrecked person and vessel = ± 5n
Between shipwrecked person and aircraft = ± 40n
W470
(AIS1 and AIS2)
(121.5 MHz, 100 W)
As indicated above for each single frequency
Aircraft at a height of 3000 ft.
Who can receive this emergency signal in addition to my vessel?
With the exception of the W400 device, for which you ust have installed on board a
specific receiver (or you should infor the SAR unit of the presence of a an overboard
with MSLD device operating on the aeronautical band), for the other devices the reception
of the MSLD signal is possible provided they are capable of receiving the AIS protocol.
Is it possible to try the device without having to activate a distress signal?
Yes, it is. You just have to leave the ain knob on TEST postion and press the activation
button.
For the devices equipped with GPS odule (W420 and W470), the test sequence has two
odes: short and long.

The short ode checks that the device is working properly and controls the level of the
batteries.
The long ode checks that the GPS odule is working properly and generates a test radio
essage containing the position acquired by the GPS odule.
How much is the operation life?
The MSLD devices of the W4XX series guarantee a battery life of 5 years if not used,
including test cycles established for each device.
In case of activation, the battery life changes depending on the odel:
Device Battery life in case of activation
W400 24 hours at -20 degrees
W420 24 hours at -20 degrees
W470 12 hours at -20 degrees

Other devices in commerce offer the same functions but operate at different
frequencies.
So e devices in co erce have si ilar functions but use different frequencies,
particularly frequencies defined within CEPT regulation but these solutions have so e
i portant disadvantages:
•they work on frequencies that are not internationally recognized as rescue
frequencies, and so they are not detectable by SAR services.
•Generally they are devices that trans it continuously and it is possible to take the
“absence of signal” (proxi ity syste ). This solution li its the working area of the
device (10/20 eters).
•It is not possible to trace out the position of the an overboard because the signal
is too weak and requests a specific receiving device (see proble with SAR).
•Batteries ust be replaced quite frequently.
How do you install this device?
This equip ent has been designed to be used with self-inflating jackets and it is nor ally
installed:
•By using the rear flange for passing one of the fabric tapes that connect the self-
inflating jacket cover, or
•By using the appropriate bracket that allows you to fix the MSLD device to the
inflating outhpiece, or
•By using a jacket with a specific housing pocket.
Wa blee is able to offer IMO or SOLAS approved self-inflatable jackets specially crafted
for MSLDs of the W4XX series.
Is it a CE device?
Yes the device is CE Co pliant according to the RED regulation. The W400 and W420 are
also FCC and IC approved
Can this device be used all over the world?
This device can be used in quite all European and Extra-European countries; further
details can be found on the sticker of the packaging or on our website:
