2.3 Verifying Operation
Apply power to the beacon and verify operation as indicated by the beacon and Status Indicator
LEDs.
Note: See Section 3.1 for a description each Status Indicator LED,
2.3.1 Power up
When powered up, all indicator LEDs are turned on for 10 seconds providing easy verification of
operation. The beacon will begin flashing and will turn off after 40 seconds if the photodiode
detects sufficient light. Otherwise, the beacon will remain on until the ambient light rises to a
sufficient level.
2.3.2 Synchronization
For synchronization to occur, the GPS antenna (located on top of the beacon) must have an
unobstructed view of the sky. As much as 15 minutes may be required for the beacon to achieve
a GPS signal lock. Following power up, the Sync Alarm and Sync Status LEDs will turn off.
Once a GPS signal lock is achieved, the Sync Status LED will turn on. This is the normal
operating condition.
Note: After one hour of operation, the Sync Alarm will turn on if a GPS signal lock has not been
achieved. The alarm will turn off once a GPS signal is locked. Refer to Section 5 if the Sync Alarm
remains on for more than 15 minutes.
