Interesting product. No manual as yet?

Features: Standalone flarm • builtin GPS antenna • micro SD card • IGC
flight recorder • extremely small dimensions • Power input 6-16 V DC •
Power consumption typical 30mA • Weight 40 g • Compatible with all
flarm indicators (12V)

Why is it called a "Standalone FLARM" if you need a FLARM indicator
(like an Oudie)?
