Instruction manual

11
You need to increase Sensitivity Settings on the DIP switches. The original
CCS-100 instructions call the Sensitivity Settings Low, Medium and High.
They really should be called Slow (Low), Normal (Medium) and Fast (High).
The faster the sensitivity, the less the speed drops.
Cruise works but is too jerky at low speeds
When using just the tachometer signal, you have to make a trade off in the
Sensitivity Settings. The cruise can be somewhat jerky at low speeds (30
MPH or so). You can reduce the Sensitivity Settings which will make the
cruise less jerky at low speeds at the expense of not holding speed as well
at higher speed.
A simple option is to run a gear higher than you would normally run at low
speed. This softens the effect of higher sensitivity settings.
