Flashing red lights (Heartbeat sensor): if the two heartbeat sensor lights flash, this indicates that someone may be
inside the vehicle. These lights are only activated if the alarm has been triggered.
Range
The PCC's lock and unlock functions have a range of approximately 60 ft. (20 m) from the vehicle.
NOTE
The approach lighting, panic alarm, and the functions controlled by the information button have a range of
approximately 300 ft (100 m) from the vehicle.
Buildings or other obstacles may interfere with the function of the PCC.
Outside of the PCC's range
If the PCC is more than approximately 300 ft (100 m) from the vehicle when the information button is pressed, no new
information will be received. The PCC most recently used to lock or unlock the vehicle will show the vehicle's most
recently received status. The indicator lights will not flash when the information button is pressed while the PCC is out
of range.
NOTE
If none of the indicator lights illuminate when the information button is pressed, this may be because the most recent
transmission between the vehicle and the PCC was interrupted or impeded by buildings or other objects.
Heartbeat Sensor
The heartbeat sensor function
is a complement to the vehicle's standard alarm, and indicates at a distance of up to
300 ft (100 m) that someone may be in the vehicle. The heartbeat sensor only functions if the alarm has been triggered.
NOTE
The heartbeat sensor registers a person's heartbeat in the form of vibrations in the vehicle's chassis. For this reason,
the sensor's function may be impaired in areas with high levels of noise or vibrations.
