The memory capsule can be tested in or out of the release bracket.
The sequence of tests is:
1. Check Data Integrity ........................................ Beep and lights up red LED if passed
............................................................................. Stop if failed
2. Check 406 MHz Synthesizer ........................... Beep and lights up red LED if passed
............................................................................. Stop if failed
3. Check RF Power/Battery ................................. Beep and lights up red LED if passed
............................................................................. Stop if failed
4. Check internal GPS ......................................... Beep and lights up red LED if passed
............................................................................. Stop if failed
5. Turn on green LED to indicate Successful Test.
6. Flash Strobe Light to test Strobe.
If all of the above occurs, the test has been successful.
NOTE: The homing memory capsule at 121.5 MHz is inhibited during self test.
It is strongly recommended to perform the full functional self test on the memory capsule on a monthly basis.
If the thumb switch is accidentally or inadvertently put in the vertical or test position (not in the OFF or ON position), the
memory capsule would still be turned ON and would drain the battery. The chance of this happening accidentally or
inadvertently is very unlikely. However, if this should occur, the memory capsule will sound a beep once per second
and will alternately flash the red and green LED's at a rate of one per second until the memory capsule is turned OFF.
It is important that the memory capsule be turned OFF immediately (lowering the thumb switch to the OFF position,
thumb switch at rest in the front position) if this alert is ever obtained.

Internal GPS Test
Warning: The following test should never be performed more than once during the five-year life of the battery
pack! Return the unit if this test needs to be repeated (see Page 1 for return information).
The memory capsule is fitted with an internal Global Positioning System (GPS) receiver that will determine the
navigational coordinates, latitude and longitude, of its position on the globe to be transmitted to the emergency system.
When the memory capsule is turned ON, the GPS is immediately turned ON and it immediately begins acquiring data.
Initially the red Light Emitting Diode (LED), flashes once per second to indicate the memory capsule is turned ON and
operating. As soon as the GPS receiver acquires good navigational data the red LED stops blinking and the green
LED flashes once per second to indicate that the internal GPS receiver has acquired good navigational data. Once
good navigational data has been obtained the GPS receiver waits for 20 minutes before looking for new navigational
data again. If for any reason a time period of 4 hours passes without the GPS receiver being able to update the last
good set of navigational data, the message transmitted by the memory capsule will revert back to default data. At this
point the green LED will stop blinking and the red LED will flash once per second. If at any time after this, good
navigational data is obtained, this data will be transmitted, the red LED will stop blinking and the green LED will flash
once per second.
Performing the Internal GPS test
To perform the internal GPS test, make sure that you perform the test outside with a clear view of the sky. This will
help the GPS locate a satellite and reduce the amount of time the GPS engine remains on, saving valuable battery life.
If the thumb switch is held in the vertical position after the full functional self-test has finished, the buzzer will beep and
the red LED will light simultaneously. This beep and simultaneous red LED indicates that the GPS has been turned ON
and a live test of the internal GPS has begun. At this point the thumb switch should be allowed to return to its normal
OFF position. The GPS will remain ON until good navigation data has been obtained or until 10 minutes has elapsed.
If good navigation data has been obtained, the GPS will be turned OFF and the green LED will light for at least 3
seconds and the strobe will flash once. This navigation data is not saved for use when the memory capsule is turned
ON. A green LED and strobe flash indication is proof that the GPS is functioning properly and that the memory capsule
is in a location or environment where it can receive the necessary signals from satellites. If the GPS does not acquire
good navigation data, the GPS will turn OFF after 10 minutes and there will be no successful green LED indication.
This test should never be performed more than once during the five-year life of the battery pack to prevent excessive
current drain! The memory capsule must remain under observation to witness the results of the test.
