In order to power on your SS, you will first want to ensure both of your batteries are fully charged with the included battery charger. The batteries typically take 2 to 3 hours for a full charge. Once you have done this and inserted the batteries in the SS, simply press and hold the power button for 3 to 4 seconds. This will power on and activate the motors. You can enter Standby Mode by simply pressing and holding down the Mode button for 3-4 second. This will disengage the motors, but the gimbal will still be on. To activate the motors, simply press and hold the Mode button again for 3-4 seconds.
