Cobra's high performance radar/laser detectors are a great way to keep in touch with everything that's happening on the highway. The XRS 9400 alerts you to the use of nine radar and laser signals, and two safety systems. VoiceAlert™ delivers convenient audible messages so you don't have to look away from the road. Each time you turn on the detector, it runs a diagnostic check and announces that it's ready for operation.

VG-2 Alert® lets you know when you are in the presence of radar detector detectors, while the VG-2 Undetectable feature ensures complete immunity to those detectors. (This detector is also invisible to Spectre 1 detectors.) StrobeAlert® gives you advance warning of the approach of emergency vehicles for safer travel. Intellimute™ senses lower engine RPMs when you're moving slowly, virtually eliminating false alerts.

Sorry, but we cannot ship radar detectors to Virginia or the District of Columbia.

Features

Strobe Alert: The XRS-9400 will give you advanced alert of the presence and/or approach of these vehicles. This is a Cobra exclusive that works with the tens of thousands of emergency vehicles currently equipped with traffic light controlling strobe emitters, which activate red lights at traffic intersections in emergency high speed situations.

Safety Alert: The Cobra XRS-9400 will give you advanced alert of the presence and/or approach of emergency vehicles and road hazards from systems equipped with Safety Alert Traffic Warning System transmitters.

Voice Alert: The Voice Alert feature provides the user with audible messages of specific band information.

Laser Eye: This feature provides you with 360 degree detection of laser signals.

VG-2 Alert: This feature will alert you when you are under surveillance of VG-2 radar detection.

VG-2 Undetectable: The VG-2 Undetectable feature provides complete immunity to VG-2 radar detector-detectors. This system is always on and does not disable radar detection when activated.

Spectre Alert: The Spectre Alert tells you when you're under surveillance of Spectre 1 radar detector-detectors.

Spectre Undetectable: The Spectre Undetectable feature provides complete immunity to Spectre 1 radar detector-detectors.

UltraBright Data Display: A display feature that provides easy recognition of any band detected by use of band identification icons.

EasySet Programing Menu: A programming feature that allows easy, user-friendly mode selection/setting with visual guidance.

System Ready Prompt: This is a notification function which alerts the user that the radar detector has correctly completed a self-test and is ready.

City/Highway Modes: When the City mode is activated, this function filters out many of the sources for conflicting X band signals such as microwave relay towers and automatic door openers.

Digital Signal Strength Meter: This feature helps the user determine relative proximity to the target.

Audio Muting: You may choose between Auto Muting and Manual Muting. In Auto Mute mode, the alerts will be heard at the regular volume for 4 seconds, then automatically reduced to a lower level. When manually muting, you must press the Mute button while a signal is being received. This will reduce the volume of the alert in progress. The volume will return to normal for the next signal.

IntelliMute: Relative speed sensing auto mute system that virtually eliminates alerts you don't need to hear because you are either stopped or moving slowly. It senses the engine's RPM (which you have to set) and knows that you are driving at low speeds and automatically mutes alerts (except for strobe signals). Once the RPM level is set, the Cobra XRS-9400 will remember the setting.

Dim Mode: Allows you to select from three levels of brightness for the display; Bright, Dim, or Dark.

Mounting: You can mount the XRS-9400 on your dash with the supplied Velcro, or you can mount the radar detector on the windshield using the supplied mounting bracket that utilizes suction cups.
