Section One
1.0 Introducing your MOBiLert System
1.1 What is MOBiLert?
MobiLert is a dedicated system designed to help prevent loss of life
at sea. The system uses personal radio transmitters to maintain a
constant link with a central Console Unit. The moment a PTX is out
of radio range for more than 7 seconds, an alarm is sounded and the
exact GPS position is logged. The MobiLert Console will then automatically switch to a track back screen giving the direction and range
back to the victim.
1.2 How it keeps you safe
Every PTX sends out a constant radio heartbeat to the Console.
Providing your crew is wearing a PTX you can be sure that they are
within about 30 Meters of the boat. MOBiLert is an active system. Any
flat batteries, broken PTXs or failures in the transmission system will
result in an alarm.
1.3 What you have to do
As the Captain, crew safety is your responsibility.
This system will only work if it is turned on and all of your crew are
wearing PTXs. Make sure that PTXs are easy to find, you have enough
on board and every one knows how to respond to an MOB emergency.
1.4 What MOBiLert will do
MOBiLert will give the Captain piece o f mind that all crew are safely
onboard. We have put a lot of effort into making the PTX small, tough
and easy to wear. Providing they are worn properly by the crew, the
system will keep track of the PTXs
proximity and the battery condition. In the event of a MOB Emergency, MOBiLert will log the position that the PTX went missing and
provide the helmsman with instructions on how to get back to the
MOB position.
1.5 What MOBiLert can not do
MOBiLert can not replace good safety practices and procedures. MOBiLert won’t stop people falling overboard, can’t stop them drowning
and has only limited ability to find them when they are in the water.
MOBiLert should be considered the last line of defense

Section Two
Installing for best performance
2.1 A short lesson in radio frequency propagation.
The biggest benefit of the way we have done things is that the system is fail-safe. Any prolonged breaks in the radio link will result in an
alarm. So, to make it free of false alarms we need to put some thought
into the installation. The system uses a radio link in the UHF range so
the link needs to be more or less “line of sight”. This is similar to the
ships VHF radio. (At UHF frequencies, the signals can bounce off metal
and water which means that occasionally it can see around corners but
we don’t want to count on it.)
The other property of the system is that it has some ability to see
through Fiberglass and wood. It is blocked completely by aluminum
and steel so if your boat is made from these materials you have to be
very careful where the Console is mounted and look at using Repeater
Antennas to cover any blind spots.
The higher you are the further you can see. Just like the Ships VHF
radio, the higher you can install the Console’s antennas the stronger
the link to the Pendants will be. However, you still have to be able to
read the Console particularly in a MOB Emergency as it will tell you how
to steer back to the MOB location.
Once the boat gets around 40 feet and above the height of the Console’s antennas becomes even more important.
2.2 Using the External Dipole Antenna
Your MOBi-Lert kit contains an external Dipole antenna.
The purpose of this antenna is to make sure that the system remains
free of false alarms on large boats or for difficult installations.
The Dipole antenna connects to the Console via the centre RP SMA connector and need to have the self vulcanizing tape wrapped around the
SMA connector to protect the finish.
The three meter cable length is enough so that it can be mounted as
high as possible inside the vessel. The external Dipole in NOT waterproof so it must be used inside the cabin.
The self adhesive tape will stick to most dry wood, plastic, fiberglass or
glass surfaces. The cable will need to be supported with “P” clips or self
adhesive mounts to take the strain off the antenna.
The antenna will not work if it is mounted against steel or aluminum
surfaces.
It is really important that the antenna is orientated properly.
You have two options depending on your specific circumstances.
1. Mounting it vertically so that the ends point up and down.
2. Mounting it horizontally so that the ends point to the Port and
starboard sides. (Not to the bow and stern).
It is possible that for smaller boats it will not be necessary, but it if possible fit it anyway.
If there is no way to get the antenna up high and out of the wet area,
(Possibly for centre cockpit boats) then contact Mobilarm for some external waterproof antenna options.

2.3 Finding the sweetspot
Motor Yachts
If the boat is a Fly bridge cruiser,
installing the console by the steering station on the fly bridge will
provide the best coverage of the
decks fore and aft. You may need
to experiment with positions to get
the best coverage of crew below
in the saloon. Even though it is
unlikely that anyone can fall overboard from inside the saloon, it will
be more convenient for your crew
to not have to worry about taking
Pendants off when going below.
For all other Motor cursers, the
steering station usually has a good
view of the decks and is in exactly
the right place if a MOB track back
is needed. In all cases use the
bracket mount to keep the unit
clear of other dash board mounted
gear.
If possible, the best position can
often mounted on the wheel house
roof. In this case reverse the
bracket.
Sailing Yachts
Yachts with a “Dog House” or
Wheel house.
Just like the Motor yachts, mount
the Console as high as possible in
front of the steering station. Use
the bracket if possible and keep
the Console clear of other metal
instruments and the compass.
Centre and Aft cockpit boats.
The installation location is a little more critical particularly if the boat is 40 feet or longer. The challenge here is to get the Console as high as possible
but protect it from physical damage.
Mounting it on the steering binnacle will provide
good coverage and if it is high enough, no problems right up to the bow.
If you have a dodger and it is possible to mount
it above the companion way then this works really well. Good results also come from mounting
into the “Garage” above the companionway. Use
the Bulkhead Kit supplied and mount it as far away
from the other instruments in the garage as possible.
If a location on the deck above the companionway
is not an option then the next best place is beside
the companionway and as high as possible. Use the
bulkhead mount to keep it flat against the cabin
and away from your other instruments. If necessary move an existing Log or Wind instrument
down to give the Console the highest position.
Wherever you put the Console make sure that it is
clear of halyards and sheets. We have built it tough
but it won’t be able to anchor 2000 Sq feet of spinnaker.
Mounting it in the foot well of the cockpit may work
for small boats and cockpit crew but you are likely
to get false alarms if you have people working on
the foredeck. Test the unit first by putting it in the
chosen location and make sure that you have a reliable link to the Pendants at the extremities of the
boat. Only if all is OK start drilling holes.
Mounting below decks.
As mentioned, the radio waves sent by the Pendants do have some
ability to penetrate Fiberglass and wood. It is possible to mount the
Console below decks and get reliable coverage. Pick a location that is
away from metal like fridges and SSB radios and is in as much clear
air as possible.
Remember,
way to relay the track-back information to the helmsperson.

2.4 Testing for reliability
BEFORE YOU DRILL ANY HOLES…
Go through this procedure. It’s quick and may save some heart-
ache and filler.
Setup:
1. Make sure that the Pendants are charged and operating.
2. Temporarily locate the Charger in the area you intend to
permanently mount it. (See the section on installing the
charger)
3. Use tape (double sided), Blue Tack or a volunteer to locate
the Console in the place you have figured out is the best.
4. Temporarily connect power to the Red and Black wires of
the Console Power cable. (Use a cigarette lighter adapter or
even 12Volts worth of torch batteries)
5. Plug in the power cable (Don’t worry about hooking up the
GPS yet).
6. Switch the Console on and wait until it changes to the Pen
dant Status screen.
7. Attach a Pendant to the Belt Clip of some volunteers.
8. Leave one Pendant in the Charger.
Procedure:
Making sure that the Pendants can be read from the Charger
Identify the Pendant that is in the Charger.
Using the signal strength meter (Series of vertical bars beside the Pendant Status) make sure that you get 4 bars showing.
Confirm that the Pendant that is in the Charger is showing “Charging” on
the Console. Take it out and confirm that it changes to “Safe” and put it
back as see that the Console can read it as “Charging” again.
If that bit is OK then proceed.
Otherwise, as a first option, try and find a better place for the charger. As
a last resort, relocate the Console.
Making sure that that the Pendants can be read from all over the boat.
Ask your volunteers to go to all of their usual places and stop. Looking
at the display check the signal strength indicators (vertical Bars) and
look for any Pendants that drop from 4 bars to 3 or more. If after about
10 seconds all 4 bars on every Pendant are showing then move onto the
next test.
For the second test, ask the volunteers to move about the boat very
slowly. Keep your eyes glued to the Console and look for any missing
bars. The reason for the slow movement is that a “dead spot” might only
be a yard wide and the system needs a few seconds to respond. Make
sure that you cover extremes like the pulpit and crouching down at the
anchor well.
If you don’t get any dropouts then your location is good. As a final test,
send a volunteer below decks. Make sure that they can at least get to the
Charger unit without any losses of signal strength. Try other areas below
decks to see what is possible. An engine room lined with lead based insulation is always going to be a big ask, so don’t worry if this set off a MOB
alarm.

2.50 Mechanical considerations
Unlike a GPS or fish finder, you don’t have to look at the screen all of the
time. MOBi-lert will tell you when you need to look at it.
2.51
Bracket Mounting
The bracket needs to
be mounted on a flat
surface in a position that
can be seen by the helm.
Check that you have
enough clearance behind
the unit to mount the
connector(s).
The Console can be tilted
but not rotated so make
sure that you can look as
squarely on as possible.
Use the two self tapping
screws to mount into
wood. Self tapers can
also be used on fiberglass but metal thread
screws and nuts are a
better option. Either way,
if it is a wet area then
seal the holes with a
good quality marine sealant before mounting the
bracket.
Slip the two neoprene
washers onto the studs
of the thumbscrews.
Thread the two thumbscrews partly into the
console and slide the unit
into the bracket. Once
seated in the bracket,
adjust the angle and
tighten the thumbscrews.
