The fault alert occurs if GPS position is miscalculated due to bad GPS reception.
Inaccurate GPS reading will cause the GPS-303 to think that it is in a different
location, possibly further from its current location, thus the processor will
accept this as a movement and trigger the movement alarm. However, this may
only occur if the GPS-303 is installed improperly in a place where it can't
receive good signal.
To Cancel:
Send SMS “password” to deactivate the movement alarm.
Example: nomove123456

6.18.6 Over speed alarm
Over speed alarm will be triggered when GPS-303 exceeds speed limit
predetermined by you. Setup: Send SMS “speed+pspace+speed” to
GPS-303 and it will reply “speed ok!”. This means that you have set up over
speed alarm successfully.
Example: speed123456 080
.
080 refers to 80km/h. When your vehicle's speed exceeds 80km/h, GPS-303
will send SMS “speed+080!+ location” to authorized numbers.
To cancel: Send SMS “password” to deactivate the over speed alarm.
Note: Recommended minimum setting for over speed alarm is 30km/s.
Example: nospeed123456
Response:
nospeed ok
