The middle speed window is yellow and performs two functions; an icon located directly below the
window indicates each function. If the window is being used to display a locked target speed, a T-
lock icon is lit. Only the speed of the strongest target can be locked. If the middle window is being
used to display the speed of the fastest vehicle (fastest mode), a FAST icon is lighted. General
error conditions (Err) are also indicated in this window.
The green window on the right side of the display shows the patrol vehicle’s speed in moving mode
and is unused (filled with dashes) in stationary mode. The speed displayed in this window should
always correspond with the vehicle’s speedometer. If a low voltage condition occurs, it will be
indicated in this window by “Lo” appearing in the window.
Range bars
The two LED bars at the bottom of the display show the target distances of the strongest and
fastest vehicles detected by the radar.
Doppler audio
The RANGER features a speaker on the front panel for Doppler audio. The RANGER's audio is
useful as an aid in target identification. The loudness is proportional to the strength of the received
signal and increases as the target vehicle approaches. The pitch of the audio signal increases with
higher speeds.
Display dimming and infrared remote sensor
A photocell is located on the display panel to automatically adjust the brightness of the display to
the ambient light conditions. An infrared sensor is also located on the display panel to receive
commands from the remote control.
Power button
This button controls the power for the RANGER radar. When the RANGER is turned off, the
radar remembers its user settings (volume level, mode, etc.), but it does not remember speeds and it
starts up in standby mode. When the unit is next turned on, it powers up using the same settings,
saving the user the trouble of resetting the radar to his or her desired settings.
