Crewsafe V100

 Where is the best place to wear a Crewsafe V100?
In order for the Crewsafe V100 to transmit the VHF distress alerts successfully, the flexible antenna must be out of the water. This means that the unit is best positioned high on the front of a person's body, ideally at chest height. The water sensors on the base of the unit must be submerged for at least 5 seconds to automatically activate the device, otherwise the device must be manually activated.

A Water-Sensing Extension Kit (part number MOA-00202) is also available to extend the water sensing capability of the device. This allows a Crewsafe V100 to be worn or mounted higher from sea level to achieve a wider alerting range but still be water activated in an emergency.

The Crewsafe V100 is also available to purchase already integrated with a life jacket (see the Lifejacket Integration brochure for further details) which ensures that it is in the most effective position for water activation and emergency message transmission, while also assisting the casualty to remain afloat and face up in the water.

 

 Is the Crewsafe V100 compatible with other safety or man overboard devices such as a lifejacket or Jon buoy?

Yes. The Crewsafe V100 clip allows it to be attached to any strap or harness that can be threaded through the loops. The Crewsafe V100 is also available to purchase already integrated with a life jacket (see the Lifejacket Integration brochure for further details) or can be retro-fitted to existing jackets (model dependent - contact us for more information).

 

 Can anyone replace the battery in a Crewsafe V100?
 

No. Battery servicing and/or replacement can only be carried out by an authorised Mobilarm service agent. Failure to do so may compromise the integrity of the product and will void the product warranty.

 
 

 Can a Crewsafe V100 be re-used once it has been activated?

Perform a full test to check the state of the battery and how much battery life is remaining in the device. If the battery test phase fails or the battery life is below the minimum accepted for safe use, immediately take the device out of service and contact your authorised Mobilarm service agent for a replacement.If the device passes the full test, then the device may remain in service. Remember to perform a battery test every 3 months and a full test every 12 months. For extra reassurance, have your Crewsafe V100 serviced annually by an authorised Mobilarm service agent. See the Annual Service brochure for more details.

 

 Is there a different antenna available to attach to the Crewsafe V100?

Yes. A Long Wire Antenna (part number MOA-00203) can be used instead of the existing antenna when using the Crewsafe V100 with a lifejacket or survival suit.

 

 What is the procedure if I change to a different vessel and want to continue using my Crewsafe V100?
Check whether the area of operation of the new vessel is governed by different maritime regulations to your current area of operation because your Crewsafe V100 may need to be reprogrammed with a different regional profilein order to comply with those regulations.

If your Crewsafe V100 is programmed with the MMSI number of your current vessel then this must also be reprogrammed to the MMSI number of the new vessel. Contact your authorised Mobilarm service agent for assistance with reprogramming your device.

 

 Is there any set-up required before the Crewsafe V100 will transmit GPS coordinates?
 No. The Crewsafe V100 has an in-built 20-channel GPS receiver that will automatically acquire a GPS lock and transmit position coordinates in the DSC and voice distress alert.

Performing a full system test every 12 months will reassure you that the GPS Antenna is operating properly and can acquire GPS coordinates.

 

How do I configure my chart plotter so that an incoming Crewsafe V100 DSC distress alert logs a waypoint when a man overboard event occurs?
Some DSC radios can output DSC and DSE messages via a NMEA connection. When the VHF DSC radio receives the distress alert it may be able to output a NMEA0183 sentence direct to a connected GPS or chart plotter and log a waypoint of the coordinates received in the distress alert. This will plot the casualty's first known position and track them in the water with every subsequent updated position received.

Refer to your radio owner's manual to determine whether your DSC radio is capable of sending NMEA0183-compatible data to your GPS or chart plotter and if so, ensure that your GPS or chart plotter is correctly configured to accept this data protocol.

 

 How do I know that my Crewsafe V100 is transmitting emergency messages?
When the Crewsafe V100 has been activated, the Strobe starts to flash, the Status LED illuminates to indicate that the device is active and audio alerts (beeps and automated messages) warn the user that the device has been activated.

The device indicates it is transmitting a message with a long beep prior to each VHF voice or VHF DSC transmission.

The Strobe flashes twice per second during transmission and two short beeps after the message confirm the transmission has been sent.
