Introduction
ORCA® is a personal saltwater or manual-activated man overboard (MOB) alarm system
developed by BriarTek Inc. The system is utilized by the U.S. Navy and other mariners to aid in
the rescue of an MOB victim. The ORCA® system operates on 121.5 MHz and includes a
transmitter, receiver, and direction finder. When the transmitter is activated, it emits a signal from
the victim to the receiver. The receiver emits an audible alarm and displays the ship type/hull #
and serial number of the transmitter on the receiver LCD. The transmitter also emits a signal that
is received by the direction finder and other standard search and rescue (SAR) equipment to locate
the MOB.
Parts Overview (figure 1)
A - Antenna
B - Manual activation/
deactivation recess
C - Water sensors
D - Distress marker light
E – Battery door
F – Antenna tip holder
Modes
The TX104 has three modes:
♦ ARMED - Each
transmitter is ARMED
after a 3 volt CR123
lithium battery is
correctly installed.
♦ TRANSMIT - The
transmitter goes from
ARMED to TRANSMIT
mode when it is
automatically activated
by submerging it in
saltwater for a minimum
Figure 1: TX104 parts
of 3 seconds or when it
is manually activated.
After the transmitter is activated, it emits an FM signal for approximately 1 minute. This
sends the transmitter identification to the receiver. After approximately 1 minute, the
transmitter emits an AM signal. This allows the DF to track the transmitter.
♦ DISABLED - The transmitter is DISABLED when the battery is removed or the battery
runs out.
Operating Instructions
Manual activation: Remove antenna tip (A) from
holder and insert tip in manual activation/ deactivation
recess (B). See figure 2. The distress marker light
begins flashing to indicate activation. Approximately
3-5 seconds after distress marker light begins flashing,
the transmitter will begin transmitting.
Automatic activation: The transmitter will activate
when the water sensors are submerged in saltwater for
at least 3 seconds.
All Clear (deactivate transmitter): When the MOB is
recovered, remove antenna tip from holder and insert tip
in manual activation/deactivation recess. This sends an
ALL CLEAR message to the receiver and returns the
transmitter to the ARMED mode.

activation/deactivation
Wearing the transmitter
THE TRANSMITTER MUST BE WORN SO
THAT THE WATER SENSORS ARE UNDER
WATER AND WET AND THE ANTENNA IS
ABOVE THE WATER SURFACE WHEN THE
PERSON IS FLOATING. The transmitter can be
attached to a PFD using the pouch provided by the
manufacturer with the antenna attached to the collar
using a lanyard clip. In addition, the transmitter has
been designed to be worn around the neck. See figure
3. This affords the best opportunity for the signal to be
received in a man overboard event if the MOB is not
wearing a PFD.
Battery Information
Battery Lifespan—TX104 has very low current
consumption. It is recommended that the battery
should be replaced once a year and sooner if the
TX104 has been activated for more than occasional
testing. When the TX104 is in TRANSMIT mode, a
new battery will last approximately 24 hours.
Figure 3: TX104 worn around neck
Use the following steps to test the battery strength:
1. Activate the unit by inserting the antenna tip in the manual activation/deactivation recess.
2. As soon as the distress light begins to flash rapidly, insert the antenna tip in the manual
activation/deactivation recess once again.
3. If the light turns on and remains on solid for
approximately 5 seconds, the battery is useable. If the
light flashes on and off for 5 seconds, the battery is
not useable and must be replaced
Use the following steps to replace battery:
1. Using a #1 size Phillips head screwdriver, unscrew
the crosshead screw on the battery door. See figure 4.
2. Remove battery door.
3. Remove used battery.
4. Insert new 3 volt CR123 lithium battery according to
polarity diagram on the inside of the battery door.
5. Replace battery door. Grasping screwdriver with
thumb and forefinger, screw down the battery door to
45 in/oz.
6. Do not over tighten!
