Thank you for choosing MOB+!

The xFOB is waterproof down to 10 ft./3m and can be reused after 

MOB event. After an MOB-event, the engine can easily be restarted 

by;

•  dStart - 6 seconds after a MOB Event the system lets 

passenger restart the engine to pick up the missing person in 

the water. The engine can be started without reconnecting the 

xFOB. No interaction with xHUB necessary.

•  Reconnect with the xFOB by clicking once on the xFOB to 

deactivate dStart and once more to connect.

this product

Read all instructions carefully before use of this product.

FELL Marine equipment and accessories are designed to 

the best industry standards for use in the recreational marine 

environment. Their design and manufacture conforms to the 

appropriate Electromagnetic Compatibility (EMC) regulations, but 

correct installation is required to ensure that performance is not 

compromised. Please see section EMC Installation Guidelines in the 

User Manual for optimum EMC conditions.

Within the wireless range MOB+ will not shut down the engine 

automatically e.g. if you fall in your boat within the wireless range the 

engine will not stop automatically. In this event, you can shut down 

the engine by pressing the button on your MOB+ xFOB or on the 

MOB+ xHUB. Always check your wireless range before use.

WARNING

CAUTION

MOBP17001

MAN OVER BOARD

MOB Mode

 (

Man Overboard Mode

) is the safety mode of the 

system. MOB+ will automatically activate shut down of the engine 

when the STOP FOB is submersed in 4 inches (10 cm) of water or 

travels out of range from the xHUB. After 6 seconds, the system 

automatically activates Override Mode. In Override Mode any 

passenger or crew on board can restart the engine without the need 

to interact with the MOB+ system. This allows for a quick recovery of 

the missing person in the water and enhances safety.

ALARM FUNCTION:

 If any of the ALARM FOBs falls overboard 

the xHUB will 

NOT stop the engine(s)

, but sound the MOB Alarm, 

flashing on the xFOB Connection Indicator on the xHUB and blink 

red in the light circle. The alarm continues until the STOP button on 

the xHUB is pushed to disengage the alarm.

MOB EVENT RECONNECT: 

In an MOB event where the STOP FOB 

falls overboard, the person returning from the water can reconnect 

the xFOB by one click to disable MOB Mode, followed by one more 

click on the xFOB to reconnect. Alternatively, remaining passengers 

with an ALARM FOB can choose to connect one of their xFOBs.

MOBP17003

In the event that you forget your xFOB or if 

it´s out of battery - don´t worry. You can easily 

override MOB+ by holding the button on the 

xHUB for 10 seconds. The xHUB will give a 

sound signal and a yellow light signal every 30 

seconds to indicate Override Mode is activated 

so you can start the engine(s).

OVERRIDE MODE

MOBP17004

dStart

dStart is the direct restart feature in the 

MOB+ system. 6 seconds after an MOB event 

with a STOP FOB, the MOB+ automatically 

activates Override Mode to allow any remaining 

passengers in the boat to restart the engine(s) 

directly, without interacting with the system. 

The Override Mode flashes yellow and gives a 

sound feedback every 30 seconds.

EMC GUIDELINES

The guidelines given here describe the conditions  

for optimum EMC performance, but it is recognized that it may 

not be possible to meet all of these conditions in all situations. To 

ensure the best possible conditions for EMC performance within the 

constraints imposed by any location, always ensure the maximum 

separation possible between different items of electrical equipment.

For optimum EMC performance, it is recommended that wherever 

possible: 

FELL equipment and the cables connected to it are:

•  At least 3 ft. (1 m) from any equipment transmitting or cables 

carrying radio signals e.g. VHF radios, cables and antennas. 

In the case of SSB radios, the distance should be increased to 

7 ft. (2 m).

•  More than 7 ft. (2 m) from the path of a radar beam. A radar 

beam can normally be assumed to spread 20 degrees above 

and below the radiating element.

•  If possible the product is supplied from a separate battery 

from that used for engine start. Power supply voltages below 

the minimum specified 7V power source, and starter motor 

transients, can cause the product to reset. This will not damage 

the product, but may cause inability to start the engine.

• 

FELL specified cables are used. Cutting and rejoining these 

cables can compromise EMC performance and must be 

avoided unless doing so is detailed in the installation manual.
