Orange Button and Green LEDs on Standard 120V Voltec Charger
Okay, I give up. I can't figure them out. I can't find anything in the instructions. And I can't find anything online.
So, I push the orange button (hard) and the green LEDs start flashing. The LEDs settle back to: the left 2 on, and the right 2 off. Does this mean that the charger is opeating at a reduced level? If so, how do I make it operate at a higher level? Can it actually sense what's going on behind the wall (breaker size, etc)?

Yes, it means it's only providing 8 amps of current. Push the button again to get back to the full 12 amp mode. The breaker had better be a 15 (or 20) amp breaker. But there's no way for the EVSE to know if you have something ELSE plugged in to that circuit.
If you keep popping the breaker or if your EVSE detects faults, switch to 8 amps. If it works at 12, keep it there.
Try pressing the orange button before attaching the J1772 connector to the Volt charge port. If necessary, unplug the charger from the wall outlet and plug it back in to reset the charger. I am not at the charger to verify, but that is what I would try.
The 4 LEDs should definitely switch between 4 and 2 lites depending on the 8 or 12 amp selection with each press of the orange button.
The actual current consumed is determined by the charging electronics in the car.
The EVSE (charging cord) signals to the car the maximum current that it is capable of supplying. This is done by a handshake pilot signal on initial connection. Based on this signal, the charger within the car sets the charge rate not to exceed the signaled amount. This way, the delayed charge start time is calculated so charging ends at the appropriate time.
Once the handshake with the car determines the maximum charge rate it is fixed unless the charge cycle is interrupted.
Therefore, the orange button on the 120V charge card can only be used to configure the charge rate before it is connected to the car. To change it, unplug the connector at the car then push the button to change the rate, then reconnect.
