Battery Powered
The unit can provide approximately 15 hours of laser/radar detection with three rechargeable AA Ni-MH batteries, or you can plug it into your vehicle's cigarette lighter adapter (this will recharge the batteries).

Blue LCD Text Display
The XTR-540's brilliant display provides distinct visual confirmation of signals detected, signal strength, and indicates engaged modes of operation.

Patented POP Mode Detection
There are new guns out there that operate just like the instant-on guns of the past but with a very tough new twist--POP mode! This new gun is a normal K and Ka band radar gun detectable by most radar detectors made in the past 30 years until it's in POP mode. When the gun is in POP Mode and activated, a brief burst of energy, less than 1/15 of a second, is transmitted and the vehicle's speed is quickly acquired. A detector without POP Mode detection capability cannot respond to this brief transmission, but the XTR-540 can.

Low Profile Alert Periscopes
Whistler's Low Profile 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.

3 City Modes/Highway Mode
Highway mode provides full audio and visual warning of laser/radar systems while maintaining full sensitivity. Highway mode is the default setting of all Whistler's laser/radar detectors. City mode helps reduce the annoyance of automatic door openers and burglar alarm alerts by providing an initial alert (same distance as Highway Mode) then remaining quiet unless the signal strength becomes very strong. When the signal increases the unit will alert briefly to notify you of the change in signal strength.

Stay Alert
The Stay Alert feature is designed to test a driver's alertness. Within 30 to 60 seconds after the feature is engaged an alert is sounded; to show alertness, the driver must press the volume, city or the mute button within 3-5 seconds. If a button is pressed within 3-5 seconds, the cycle is repeated. If a button was not pressed within 3-5 seconds the unit alarms at full volume and the display shows an unique visual alert.

Quiet/Auto Quiet Modes
Pressing QUIET before a signal is detected engages Auto Quiet Mode, which automatically reduces the audio level after the initial warning to a low audio level setting. Pressing QUIET during a radar/laser encounter silences audio alerts, while allowing visual alerts to keep you informed.

Alert Priority
When two or more signals are received at the same time, the alert priority is: Laser, VG-2, Speed Radar, Safety Radar.

Example: If X band is alerting, then suddenly a VG-2 signal is detected, the VG-2 warning will override the X band alert.

Vehicle Battery Saver Mode
The Vehicle Battery Saver Mode automatically shuts off your detector within 3 hours if you forget to turn it off. The timer is reset if the detector is turned off, unplugged or any button is pressed before the 6 hours have expired. The detector will alert you with an audible and visual warning before it shuts off.

Safety Warning System--SWS
This relatively new radar is not for speed detection at all, it is used to keep you informed of highway safety. Transmitters are installed and programmed (for example: in emergency vehicles) to make you aware of possible situations that may require your attention, such as: ambulance vehicles that are moving or stationary, road hazards ahead, road construction delays or detours, etc.

VG-2 Detection Mode
The VG-2, also known as a "radar detector detector," is a special receiver used by police to detect signals radiated by a radar detector. The XTR-540 alerts you its presence, and thanks to Whistler's patented VG-2 cloaking technology provides undetectability.

3.0 out of 5 stars Pretty good, but I should have gotten the XTR-440 or a non-battery powered model, October 11, 2010

This review is from: Whistler XTR-540 Cordless Radar Detector (Electronics)

The only difference between this detector and the xtr-440 is the compass mode, which I did not find worked well when I bothered to calibrate it, which you have to re-do every time you move it from the mounted position. So now I just don't use that feature, and could have spent a bit less to skip it. Also, when you have the unit on and plugged in to DC power, it will invariably shut itself off with much beeping one hour into your drive. It's not an issue on short drives, but on any car trip of length, be ready to unplug it and plug it back in when it starts shutting itself off every hour.

I've had the XTR-540 for about a week now, and so far, so good. Nice display, nice suction cup mount. Minimum number of false alarms. Fairly intuitive setup and menu system. Seems to be holding a charge fairly long. Nice compact size for a cordless unit.

This new whistler is great!!! The fact that it is cordless makes it universal from car to motorcycle. It's charger works very well when plugged in to a power point for a short time. The XTR-540 lasts a whole week on one charge on my work commute, (approx 12 hours). Since my commute is 45 minutes to and from work, the battery saver set to 1 hour works well for me.
On the other side, this unit will detect radar alot further than the eye can see, if it alarms, you better believe it.
Buy it!!! for the money, it's the best on the market. It's better than my last $400.00 Escort that was stolen.
