How do I find the settings for the fault distance accuracy? Currently the tracker is around 200 meters off.

You can adjust the fault distance accuracy by changing the upload time interval. Send an SMS with the format:
INTERVAL*12345678*xxx
Replace xxx with a value between 30 and 999 seconds. The default is 30 seconds.

A shorter interval improves accuracy but uses more battery and data. A longer interval saves power and data but reduces accuracy.
