Set Braking Thresholds

Use the Set Braking Thresholds dialog box to enter the rates of deceleration that define hard braking
and extreme braking. Accident Logs are created based on the thresholds set in this dialog box. Any time
the car's braking threshold exceeds these set limits, the event is logged in the Trip Report.

To set braking thresholds:

1. Select Set Braking Thresholds from the CarChip menu. The

CarChip / Set Braking Thresholds

dialog

box displays.

2. Enter your desired hard and extreme braking thresholds or click Default to use the software default

threshold settings. The default braking thresholds are: 0.35 and 0.50 G (US & Metric) and 3.4 and
4.9 m/s

(S.I.).

3. Click OK to save the new settings. Click Cancel to exit the dialog box and retain the previous

settings.

Note: The extreme braking threshold is also the threshold that triggers the audible alarm on the CarChip
Pro, CarChip Fleet Pro, CarChip E/X with Alarm, and CarChip Fleet with Alarm models. When this braking
threshold is exceeded in a vehicle, the alarm sounds five times. See Enable CarChip Alarm for more
information on using the CarChip Alarm feature.
