EPIRB1 User Manual
11 Version 00.02 09/06/2014
Because the test transmits a short burst on the aircraft distress frequency
of 121.5MHz, please only carry out this test in the first five minutes of each
hour.
It is recommended to test your EPIRB once a month.
The amber test result indicates the battery has been used for over one
hour or the allowed number of tests has been exceeded. The EPIRB will
still operate normally in distress, but the battery should be replaced to
ensure the full operating life when your EPIRB is needed.
5.2 GPS Test
WARNING: AS TESTING THE GPS RECEIVER EXPENDS SIGNIFICANT AMOUNTS
OF BATTERY ENERGY DO NOT TEST THE GPS OPERATION MORE THAN ONCE A
YEAR. TESTING THE GPS RECEIVER IS LIMITED TO 12 TESTS OVER THE LIFETIME
OF THE BATTERY, AFTER THIS THE GPS TEST WILL FAIL TO ACTIVATE.
THIS TEST MUST ONLY BE PERFORMED WHERE THE EPIRB HAS A CLEAR AND
UNOBSTRUCTED VIEW OF THE SKY. THIS IS REQUIRED TO ALLOW THE GPS
RECEIVER TO ACQUIRE A SIGNAL FROM SUFFICIENT SATELLITES TO ALLOW IT
TO DETERMINE A POSITION. MAKE SURE THE AREA MARKED ‘GPS ANTENNA’ IS
NOT OBSTRUCTED.
Press and hold the TEST key for ten seconds. The LED will illuminate red to
indicate the key has been pressed then start flashing.
Note: If the TEST key is released before ten seconds, the EPIRB will enter the self
test mode.
After ten seconds the LED will change to a long red flash and a short green flash
until either a position fix is obtained or the GPS test fails. A successful test will be
indicated by the strobe flashing and the green LED flashing. The number of green
flashes indicates the number of GPS tests remaining. The unit automatically turns
off after the test indication.
If there is not GPS position received a GPS position after five minutes, a failure will
be indicated by the red LED flashing after which the unit will turn off.
The test can be ended at any time by holding the ON key for one second or by
holding the TEST key for five seconds.
