User Guide GT-268Xi High Performance LASER-RADAR DETECTOR...
Please record the serial number of the unit in the space provided in the accessories section of the guide. To fully acquaint yourself with the operation of your Whistler detector and to better understand the differences between detecting radar, laser, and safety radar signals, we recommend reading this entire guide or visiting our FAQ page on our website www.whistlergroup.com...
INSTALLATION Windshield Mounting • Mount the unit as low as possible near the center of the windshield. • Do not mount the unit behind wipers, ornaments, mirrored sunscreens, etc. These obstructions have metal surfaces which can affect radar and laser signals and reduce critical warning time.
INSTALLATION Windshield Mounting • Install the two suction cups and rubber bumper onto the bracket by fitting them into their holes. • Press the suction cups onto the windshield at the location you have chosen. Rubber Bumper IMPORTANT: Some newer cars have a plastic safety coating on the inside of the windshield.
INSTALLATION Power Connection • Plug the small end of the power cord into the unit’s power jack. • Plug the large end into the vehicle’s cigarette lighter socket. NOTE: Cord fits tightly into detector. When installing the cord, expect some resistance. Fuse Replacement The lighter socket plug is equipped with a replaceable 2 amp, 3AG fuse located behind the silver tip.
OPERATION Power On and Self-Test Each time your Whistler detector is turned on, an automatic self-test sequence confirms that the speaker, visual displays are functional along with many of the saved settings. To increase the volume, continue turning the volume knob.
OPERATION Auto Quiet Mode Auto Quiet mode provides an alternate alert pattern approximately 5 seconds after a radar or safety warning system signal is detected followed by clicking. The clicking will continue for as long as the detected signal is present and for any new signal within 20 seconds.
OPERATION City/City 1/City 2 Modes Whistler’s City Modes are designed to reduce the annoyance of automatic door openers, intrusion alarms and other devices which share frequencies with police radar. Generally, X band is used for these devices. • Press City to cancel Highway Mode and engage City Mode.
1 = weak signal, 9 = strong signal Alert Periscopes Whistler’s Alert Periscopes provide an added attention getting visual alert. The two extra LEDs flash on and off when the unit alarms to provide a unique visual alert. This alert can be programmed, through the Option Select Mode to: 1.
OPERATION Dim/Dark Modes Dim/Dark Mode reduces the illumination of the display. • Briefly press and release the Dark button to reduce illumination to a Dim setting. • Briefly press and release the Dark button a second time engages Dark Mode. In Dark Mode, the display goes dark for as long as a signal is being detected and for 20 seconds after, then the display returns to the dim setting.
OPERATION Field Disturbance Sensor Rejection (FDSR) Traffic Flow Sensor Rejection (TFSR) Recently many new products that operate on police radar frequencies have been causing nuisance alerts to radar detectors. These radar based sensors are installed alongside the Highway and more recently on vehicles used as lane change assist / blind spot detectors / collision avoidance systems.
OPERATION Ka Narrow Mode Many countries do not share the same Ka radar guns as the USA. Having a radar detector that scans the complete Ka band may not be necessary if your Country is only using one or more of the following (34.0 or 34.3 GHz). See Option Select Mode to engage Ka Narrow mode.
OPERATION Segmented Selectable Laser Receiver The laser validation windows are separated into segments allowing for customization in your country. Segment Pulse Rate valid up to 900Hz valid from 1100Hz - 2000Hz valid from 2000Hz - 3000Hz valid from 3000Hz - 4000Hz, valid from 900Hz - 1100Hz valid for the TraffiPatrol XR The L c segment is an area known to have laser falsing from...
OPERATION Safety Warning System™ SWS In communities where transmitters are located, the Safety Warning System™ can transmit over 60 messages. When an SWS signal is detected an unique audio alert is sounded and an “S” is displayed to indicate an SWS message has been received.
OPERATION Feature Display Shows To Change Option D for ON, 1. = ON (default) Laser Segment L1 L 1. Q for OFF 1 = OFF D for ON, 2. = ON (default) Laser Segment L2 L 2. Q for OFF 2 = OFF D for ON, 3.
OPERATION Stay Alert Feature The Stay Alert Feature is designed to test a driver’s alertness. To engage (when the unit is not alarming): • Press and hold the City button for approximately 2 seconds. Release the button during or immediately after the alert is given.
Pulse (or instant-on) radar is more of a threat than conventional radar because it remains “off” until activated to measure the speed of a targeted vehicle. When a pulse type transmission is detected, your Whistler detector sounds an urgent 3-second audio warning and the display shows a “P”.
RESET FEATURES Reset Features All user features can be reset to factory settings. • Remove Power from the unit. • Press and hold the Quiet button. • Restore Power to the unit. (power switch turned on) • Wait for 2 beeps. •...

SPEED MONITORING TECHNOLOGIES ARE DETECTORS LEGAL? Check with your country’s laws regarding radar detector ownership and use. Check for loose lighter socket; tighten and clean. It is the responsibility of the individual radar detector user to know and understand the laws in your area regarding the legality of the use of radar detectors.
For best protection, keep these points in mind: • Because the vehicle’s license plate or headlights are the laser gun’s primary targets, mounting the Whistler detector on the dashboard can improve laser detection at short range. • Do not follow closely behind any vehicle you cannot see through.
SPEED MONITORING TECHNOLOGIES This laser/radar detector receives signals from traffic radar guns at X Band (10.500 - 10.550 GHz), K Band (24.050 - 24.250 GHz), and Ka Band (33.400 - 36.000 GHz). NOTE: Your radar detector is designed to alarm if an officer is transmitting on any one of the above radar bands.
SPEED MONITORING TECHNOLOGIES NOTE: The latest tool Police have to detect radar detectors is called Spectre. Spectre can detect the majority of undetectable (VG-2) laser/radar detectors on the market. It is the responsibility of the individual radar detector user to know and understand the laws in your area regarding the legality of the use of radar detectors.
