WRU Deployed

D.3 WRU Deployed

If the WRU is already deployed, a vertical tilt has the following effect:

 Geophone Down – If Sleeping, takes three to four seconds to wake up. If in Standby or

Armed displays the battery status, deployment self-test status, and re-acquires the GPS

position.

 Geophone Up – All lights light. If placed flat within 5 seconds, the WRU undeploys.

The following table shows how the LEDs light up during normal operation with no vertical tilt

for a deployed WRU.
