У вашего броузера проблема в совместимости с HTML5
After some tests i've found the following good solution:
1) make sure to install the 1.5.7 fw release (if you have 1.6.8 downgrade it to 1.5.7)
2) update your P3 standard with Magic Power 5.0
To downgrade to 1.5.7 fw release: http://forum.dji.com/thread-52777-1-1.html
To apply the power update with Magic Power: http://www.phantompilots.com/threads/how-to-update-tx-power-with-magic-power-v5-0.87654/
