Both are in the radio setup menu -- Click the left arrow to get there
Sticks and Pots -- setup menu 5 will give you a three-step process to calibrate the sticks and pots. Don't over-stretch the sticks, just move them along the axes for the full range of motion. Be sure and center the pots by moving the blue notches to the topmost position.
Battery Voltage -- if you have a multimeter, you can calibrate the radio voltage display on setup menu 4. Most of the screen displays internal register settings and is used for debugging, but the bottom item is used to calibrate the voltage. Attach a voltmeter to your battery, and match the radio's voltage level to that of you voltmeter. Back on setup screen 1, you can see the voltage alarm level. For LiPo batteries, 9.6 is a good value.
