to “NEXT” (up) will activate the 121.5 Mhz. audio. The 406 Mhz. to 406.1 Mhz. audio is not
affected with this switch feature.
While in the normal mode, the 406 / 406.1 receiver continuously remains active and as soon as
a signal is received it is processed. Once processed the first 406 / 406.1 page, the MESSAGE
page, will appear and if no errors occurred the appropriate LED (long or short) will illuminate
green. If there were errors, the appropriate LED will illuminate red. Toggling “NEXT” will then
change to the ERROR page if there were any errors, or the 406 / 406.1 VALUES page if no errors
occurred. Further toggling of the function switch to NEXT will then display the 406 / 406.1
TIMING page, toggling to PREVIOUS will cause the previous screen to display, either the ERROR
page if errors were present, or the MESSAGE page if no errors were present.
POWER METER MODE
When selecting the POWER METER mode, the tester functions the same as if in the one shot
FIELD STRENGTH mode except it will measure the amount of RF power being applied to the
built in ANTENNA LOAD located on the side of the tester. If the ELT is not connected to the
ANTENNA LOAD, the tester will still receive it, however an error will occur, and no power will be
indicated.
If in the FIELD STRENGTH mode, and the ELT is connected to the “ANTENNA LOAD” and a
transmission is made, the “SHORT” and “LONG” LEDs will flash alternately and a message will
display to warn that the ELT should be connected to its antenna or the tester switched to the
“POWER METER” mode.
REVIEW OF PREVIOUS TEST RESULTS
This mode can only be entered when the tester is first turned on. After the opening page, a
page will display allowing you to continue making tests, or to view previous tests. Use the
FUNCTION switch to make your selection. Once in the review mode, you may toggle between
the saved pages which have been stored in the order that they occurred. The lights will
correspond to the displayed page. To delete the saved pages (all), another screen will prompt
you to either continue with a series of tests, or to start a new series of test. If you toggle
previous, the memory will be cleaned off of all the previous tests, while toggling next will add
the next tests to those already stored in the memory. Once the memory is full when the tester
is turned on, it will automatically reset the memory prior to starting a new series of tests,
removing all previously stored test results.
