I guess once I get the hang of what this says it should be easier. I cut and pasted the following programming on this post.
What I can't seem to understand is how to change what the esc is programmed to. Ex: how to change cell type? It doesn't really say how to change it; just what it's set to. I think they assume I've done it before.
And what is TIMING mode and what should it be?
Call me dense or what?

Thanks for any help understanding this:

Towerpro 30-N ESC Instruction Manual
A) Connection Step:
1) Connect the motor and receiver to the speed controller
2) Remove battery power from the speed controller.
3) Turn on the transmitter.
B) Programming Setup:
1) Move throttle stick to full power position (UP Position).
2) Reconnect battery power to the speed controller
3) After 3sec you can hear (all sound is 3times)
∮— CELL Type AND Number
∮— — BRAKE
∮— — — TIMING MODE
∮— — — — PWM
4) When you need to go into the programming menu, move the throttle stick to MIDDLE position.
C) Programming Menu:
1) TYPE & NUMBER OF CELLS (AUTO-CUT VOLTAGE)
•— NiMh/Nicd AUTO（0.8V/CELL*）
•— — 3 LIPO （2.75V/CELL）
•— — — 4 LIPO（2.75V/CELL）
• — — — — 5 LIPO（2.75V/CELL）
2) BRAKE
••— NO
•••— — SOFT
•••— — — MID
•••— — — HARD
3) TIMING MODE
•••— 2 º
••••— — 7 º
•••••— — — 15º
•••••— — — — 30º
4) PWM
••••— 8KHZ
•••••— — 16KHZ
•••••••— — — 32KHZ
If the option is set as you need, then move the throttle stick to UP position.
After you hear the LONG BEEP, the option will be saved. Then the system will go to the programming menu and you can setup other options.
When all the required options are being setup OK, move the throttle stick to the DOWN position. After 1sec the system will save all options. Then you can start the motor now !!
D) Remarks:
∮ Signify the rhythm of the ESC emits
• Signify short buzz
— Signify long
