SECTION 5 - OPERATION
5.1
General
The memory capsule is designed to be automatically deployed and activated. The memory capsule is designed to
operate best while floating in water. Hand held operation should be avoided when possible. Do not operate inside a life
raft or under any similar cover or canopy.
Changes in the laws governing memory capsules have mandated that the memory capsule be armed at all times. If
certain criteria are met, the memory capsule will begin transmitting.
The memory capsule is equipped with sensors to detect when it is no longer in its bracket (a deployment condition)
and other sensors to determine if it is in water.
Two conditions must be satisfied for the memory capsule to automatically activate:
1) It must be out of its bracket,
2) It must be in the water,
Note: Either condition by itself will not automatically activate the memory capsule.
The memory capsule is designed to allow the user to perform periodic testing while the memory capsule is in the
release bracket to assure a functioning memory capsule.
5.2
Automatic Deployment and Activation
Automatic deployment and activation occurs when the vessel sinks and a hydrostatic release device frees the memory
capsule from the bracket allowing it to float to the surface. Built-in sensors detect that the memory capsule is no longer
in its bracket and is in water. This condition will automatically activate the memory capsule.
Note: Transmissions of the 121.5 MHz and 406 MHz signal will not occur until 100 seconds after activation.
