My bulldog Model 2010 Alarm is too sensitive and

I got this from their website.

Adjusting the Shock Sensor Sensitivity
To adjust the shock sensor, disarm the system, press and hold Button #3 (Finder) until the alarm chirps four times
(approximately five seconds), immediately release the button. Tap your vehicle’s hood above the alarm at the sensitivity
level you wish. The harder you hit the car the less sensitivity the alarm will be. The alarm will then chirp three
times. The shock sensor is now set at this sensitivity. Any shock that is equal to, or greater than this sensitivity,
will sound the alarm. Set the sensitivity as often as you wish; however, the sensitivity level will remain set until
the battery is disconnected or you reset it. If you do not tap the car it will automatically go to maximum sensitivity.
This setting is only acceptable if the car is parked inside a garage. NOTE: The factory setting on the shock sensor
should be acceptable for most vehicles.
