3. INSTALLATION
NOTE: Be sure to load the activation tape EXACTLY as described in this section.
Failure to do so may affect deployment.
If your AISLink MOB is not already pre-installed into the life jacket, please carefully follow
the instructions below. The diagrams below assume that the life jacket inflation tube is on
the left hand side (as viewed). If the tube is on the right hand side, then the tape should
be fitted on the opposite sides shown. When reviewing this installation section, please note
that there are two bracket mount locations (an upper and lower location) which exist for
flexibility to vary the fit of the AISLink MOB. The upper location is the preferred mounting
position for most user fit scenarios.
Installing the activation tape: Take the oral mounting bracket or the installation
mounting bracket and pass the activation tape through the loop as shown below.
The activation tape must be
inserted into the activation slide.
You must remove the activation
slide from the MOB. Depress
either the left or right arming
retainer and push the slide either
right or left. The antenna will
deploy and the MOB will activate.
To deactivate your MOB, press the “TEST/OFF”key until the LED flashes red twice,
then release.
There is a front and rear section of the
activation slide. Place the rear of the activation
slide so that it sits over the activation tape and
then pass the activation tape through the slot in
the middle. As the tape is threaded through the
middle, ensure that the tape is positioned
between the small protrusions
of the two up stands on the

NOTE: When loading the activation tape, the tape must be positioned between the
arming retainer and activation slide as shown below, or the MOB will fail to deploy.
In all installation scenarios (A –E) below, ensure that the installed MOB is
tethered to the life jacket using either of the tether attachment points (top of
MOB or bottom of MOB) shown in the following images. When attaching the
tether to the life jacket, ensure that the knot used is secure. Also make sure that
the location of attachment will not lead to strangulation of bladder or any other
potential bladder failure.
In all installation methods described below:
Determine the best place for fitment.
Ensure location is not within a heavily tapering section of the bladder.
Ensure that the inflated life jacket will be able to provide a linear pull on the
activation slide, perpendicular to the side of the product and with enough bladder
width protruding to ensure full activation slide removal.
On completion of fitting the MOB, the tape should be tight enough to provide
enough movement when the bladder is inflated to completely remove the slider
from the product. Do not over tighten the tape as this may allow the slider to
become dislodged under repeated movement of the life jacket.

to regularly inspect the reflective strips used to adhere the installation bracket to
the life jacket. These strips may not adhere well to certain fabric and the adhesive
on these strips may degrade over time, requiring that the strips be replaced.
4. MMSI configuration
If your vessel has a DSC enabled VHF radio telephone, it is strongly recommended to
program your vessel’s MMSI number into your MOB. This will allow the MOB to send the
details of the man over board incident directly to the radio and sound the alarm.
4.1 Self-Identification
The MOB is supplied with the self-identification number pre-programmed. This number is
specific to each MOB and cannot be changed. The MMSI displayed on the DSC receiver
will always start with ‘972’ irrespective of the country in which it was purchased.
4.2 User MMSI
(Applies to DSC enabled units only)
To be able to send DSC messages to your vessel, the MMSI number of the vessel needs to
be programmed into the MOB. This is achieved using the downloadable PC software or
the web programming software available on the AISLink MOB product web page.
