7.2 Speed Limits
TR-206 implements high speed alarm and low speed alarm. There’re two
parameters for the function to work. One is the speed limit (OI / OJ). The other
one is the hysteresis range (OP). Once the speed alarm is detected, the alarm
flag of alarm status is set and a report is sent. The alarm flag will be
automatically dismissed if the alarm condition is disappeared. Speed alarm
detection requires GPS information so the GPS should be turned on. Please
refer to chapter “5. GPS” for the setting. Please refer to the illustrations below
for the detection behavior.
