4 •sMRT V100/V100X overview
The sMRT V100/V100X is a multi-system Personal Locating Device
designed to RTCM Standard 11901.1 specifications for use during a man
overboard emergency.
The integration of VHF DSC and AIS technologies equips mariners in
distress with life-saving technology to vastly improve the likelihood of rapid
location and recovery by a vessel or Search and Rescue (SAR) authorities.
How the sMRT V100/V100X works
The sMRT V100/V100X uses the marine VHF radio band to
transmit DSC distress alerts and updated GPS positions regularly
from the casualty in the water to VHF DSC radios, as well as AIS
equipped vessels within range.
A 10 second delay period prior to activation is designed to avoid
the device being activated accidentally.
The sMRT V100/V100X transmits AIS and emergency VHF DSC
transmissions after activation. AIS transmissions take precedence
over VHF DSC transmissions and will be transmitted first. The
sMRT V100/V100X uses an internal GPS receiver to acquire a
position within approximately one minute of activation. The
device then sends VHF DSC and AIS transmissions containing the
device’s current position.
Some marine radios are able to output a waypoint of the GPS
position embedded within distress alerts to chart plotters. AIS
alerts are routinely displayed on Electronic Chart Display and
Information Systems (ECDIS). Compatible chart plotters or ECDIS
can use the AIS data to provide the direction and rate of drift of
the casualty, as well as range and bearing information.
Emergency alerts operate on a timing schedule and are repeated
at regular intervals to update rescue teams and assist in tracking
the survivor in the water. The STROBE light on the device flashes
once per second after activation and assists with visual homing at
night or in poor weather conditions.

Prevention of accidental activation
The flush-mounted design of the SWITCH LOCK, ARMING
SWITCH and ACTIVATION TAB prevents the device from being
accidentally activated. In addition, manual activation is a three
stage process, requiring the user to remove the SWITCH LOCK
and slide the ARMING SWITCH to the [READY] position to
arm the device. The user must also remove the ACTIVATION TAB
to activate the device.
If the device is accidentally activated, the deliberate warning
period after automatic activation enables the user to switch the
device [OFF] before transmissions commence.
To help prevent false alarms:
Keep the device away from young children and educate all
users in device operation and the ramifications of false alarms.
