The lost-copter alarm was switched on with the sticks

What ArduPilot says:
- Locate Copter alarm
Disarmed, with the throttle at zero, the roll and pitch sticks were both held at their maximum (right and back) for one second. ArduPilot then sounds the buzzer continuously so that a copter lying in grass can be found, and says so once. It stops when the sticks are released. The gesture is off when a switch has RCn_OPTION 30 (Lost Copter Sound), which does the same job.
