6.8LEDindicationofGPSx
When the RLB-36 is in On mode, the red LED, Light Emitting Diode, ashes every 1 second
for the rst hour then 3 seconds after to indicate the RLB-36 is turned on and operating. As
soon as the GPS receiver acquires good navigational data the red LED stops blinking and
the green LED ashes once every two seconds to indicate that the internal GPS receiver
has acquired good navigational data. The color of the On mode LED that ashes once every
1 or 3 seconds in On mode always indicates whether the 406 message being transmitted
contains good navigation data or default data. Green indicates good navigation data, red
indicates default data. Once good navigation data is acquired, the data is put into the digital
message of the next 406 MHz transmitted burst. 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 RLB-36 will revert back to default data. At this point
the green LED will stop blinking and the red LED will ash 1 every 3 seconds. If at any time
after this, good navigational data is obtained, the green LED will ash, this new data will
be transmitted in the following burst and the green LED will continue to ash once every 3
seconds.
6.9 OLED display
The Organic Light- Emitting Diode (OLED) display in the beacon is used as a secondary
indicator, supporting the green/red LED and the beep sound to indicate the status of the
beacon during the self test and emergency operation.
In self test, the OLED displays the test result of each step with “√” indicating a pass and “X”
indicating a failure. There are total ve test steps: EEPROM content, phase locker loop, 406
power output, internal GPS module and the strobe light. If all tests pass, “smiley face” emoti-
cons will be displayed at the end of the self test mode. This will be followed by the GPS co-
ordinates horizontally scrolling through the display, provided the beacon has a downloaded
external GPS location.
A long GPS test may be invoked by holding the switch in test position after self test com-
pletes. The display will show the letters “GPS” moving left and right while the internal GPS
is acquiring coordinates data. Once the data is acquired, the coordinates will scroll through
the display as a conrmation that the data was successfully acquired.
When the beacon is activated, the display will show a brief welcome message. The beacon
then begins to send 406 MHz emergency signal bursts. After each 406 burst, indicated by
a beep, GPS coordinates will be displayed, provided the data was acquired. The display
animates the sending of the 406 message. The display also provides a battery gauge which
appears for approximately 10 seconds each time between the 406 bursts.
SECTION 7 – CARE AND MAINTENANCE
7.1 Routine maintenance
At least every ninety days, the oat free mounting bracket and beacon should be inspected
for deterioration and/or residue buildup that may affect the function of the beacon or auto-
matic release. Part of the visual check includes checking the antenna for tightness. Clean
the beacon and the mounting bracket to remove residue buildups. It is recommended that
the beacon and mounting bracket be wiped with a damp cloth.
Carefully inspect the beacon case for any visible cracks. Cracks may admit moisture, which
could falsely activate the beacon or otherwise cause a malfunction. Any cracking observed
should be immediately referred to ACR for evaluation by calling 1-800-432-0227 ext. 2155 in
the US, or [phone] ext 2155 elsewhere.
7.2 Battery replacement
The battery must be replaced by the date indicated on the beacon or every ve (5) years,
whichever occurs rst. At each inspection, check the time remaining until replacement is
required. The battery should be replaced if the beacon has been activated for any use other
than the self test.
