Laser Signature Id (Lsid); Segmented Selectable Laser Receiver - Whistler MFU440 User Manual

OPERATION

Laser Signature ID (LSID)

Identifies the Laser gun's pulse rate or PPS (Pulses per
Second) that is transmitted by the speed laser gun.
LSID may also be used to identify other forms of laser
sources such as LACC (Laser Assisted Cruise Control)
systems found in some high-end vehicles. If the Laser
PPS information displayed is due to another source
such as local airports or LACC, LSID allows you to lock
out this rate from giving you the continuous audio
alert during this and any new encounter of the same
rate.
To lock out a PPS, press the Quiet button during the
Laser alert. This will place an * on the screen beside
the PPS rate and lock out this signature ID. Any new
encounter with the same Laser Signature ID will
provide the display information and two quick beeps.
Caution: Do not lock out a PPS rate if it is close to
known speed laser guns.
