Hello everyone,
Last night I started the setup process of my DJI Phantom. I'm very excited to use it but want to proceed patiently with the correct steps.
First off my battery seems to be stuck in CV mode(flashing green and red). It's been in this mode for a couple hours and feel that is too long. I have other DJI batteries I purchased; should I try another one? After doing some research I found out your not supposed to connect everything first before you connect to the outlet :shock:. Hopefully I didn't short it!
Secondly, do need to calibrate the IMU via the software and driver download before I fly? The reason I ask is because I started the unboxing process following the DJI video steps which doesn't include doing the computer calibration:

Appreciate the feedback in advance!
You didn't short it out....they just do that sometimes.
As for your battery question; I've had a few batteries do that flashing red/green for hours thing. I have a volt-meter to check the power of the batteries(a must have), and found them to be 99% charged, and 12.5+ volts; in other words, fully charged.
You might have a lose wire in the 4 wire balance plug-check that all those wires are firmly seated into the plug.
The order in which you're supposed to connect the battery to charger is; plug the charger into the wall, plug the yellow cable into the charger, then plug the balancing port into the middle port. Make sure the left switch is set to LiPO, and the right switch can be set to 3A(it will default to 1.8 or something-so don't worry about it).
When you disconnect the battery; pull the balancing plug first, then the big yellow plug.
Getting back to your calibration question; plug the USB cable from the Phantom into your computer-open up the Naza-M Assistant, then plug a battery into your Phantom-and wait.
Click through the tabs-move the controls around and just look at everything-don't change anything yet. After the IMU's have warmed up-the page with the calibration on it(I think it's in advanced), you will see a button that says "calibrate IMU's" or something like that. Click that button. If it says "calibration not needed" or something like that-you're good to go.
Also, check that your lost communications page has the aircraft "return for landing", and not "land" checked, and that feature enabled. This is also for low voltage.
There are about 5? video's from DJI. Watch all of them, twice
Before you take-off, you want to know what everything does-and, you want a "plan" in the event you lose orientation with the aircraft. It climbs very quickly....but, altitude is your friend. Fly ONLY in GPS mode for several flights. Don't be tempted to flip the switch into Atti mode too soon. This aircraft will lull you into a false sense of security-it's pretty easy to fly. But, it's also very easy to lose orientation, and therefore lose control. Especially if you are low to the ground, with fences and tree's around.
Learn about "Home Lock"....that feature is your new best friend. When the aircraft is more than 10 meters way, flip that switch-you will see a yellow flashing light along with the green-that confirms home lock is enabled. Now, no matter which way the aircraft is pointed-pulling back on the right stick brings the aircraft back to you....this allows you to regain control/orientation. Make sure you see the rapid series of green flashes before take-off. That means your home point has been recorded. When it's ready for take-off, you should just see a steady 2 green flashes.
In GPS mode, if you don't touch the right stick, the aircraft should hover and maintain altitude within 8/10ths of a meter vertically, and 2.5 meters horizontally. So, if the Phantom is moving quickly towards disaster-release the right stick, make sure you're in GPS mode, and add power to climb. Then, you can use "home lock" to bring the Phantom back.
