Continuous chirping I have the above installed in my 2001 BMW. It has worked very well until now. It is chirping every 10 seconds, whether in city or highway mode. What do you think?

When changing the Settings on your detector, please keep in mind: Each time the unit is turned On the factory settings of Highway and Auto Mute-On will be set. They can be changed while the unit is in use as described in the following sections.
Assistance Muting An Alert
Your detector allows you to quickly turn Off an audio Alert by momentarily pressing the Mute button. If you press the Mute button a second time during the Alert, the audio Alert will be turned back On.
Auto Mute Mode Auto Mute will automatically reduce the audio volume of all alerts after four (4) seconds for as long as the signal is detected. The factory setting for Auto Mute is On.
Highway/City Mode Setting your detector to City mode delays all X band audio alerts at lower signal strength levels. (A single beep will sound when the signal is first Notice detected.) This will reduce false alerts while you are driving in, or near, urban areas where there are many sources for conflicting X band signals such as microwave towers and automatic door openers. To change settings, follow the procedure listed below, which indicates what you will see and hear as you complete each step. The factory setting is Highway mode.
Highway Mode City Mode
Mute Button Press and release
To Turn Auto Mute Off X Ka L S
City Button Press and release
Press and release the Mute button while no alert is occurring.

Whistler xcs 800 says c1

Yes, because the unit is in City 1 mode. Most Whistler models have more than just a "City" mode. Pressing the CITY button again will toggle through the different city modes and return to HIGHWAY mode.

I have a rather old Whistler 3300 radar detector with the antannae unit in front of the radiator and the suction cup unit on the front windshield for rear detection. I've had it forever and love it. ...

Here are the steps from Whistler's FAQ page on their website:

When the display shows an "R1" type error on the display or the unit clicks (flashing either the Green power LED or the Yellow city LED), it means that the link between the inside and outside unit has failed. Generally this is caused by the receiver's (outside unit) cable becoming unplugged from behind the console (inside unit).
NOTE: The receiver cable is the straight one plugged into the "Radar 1" jack. The laser receiver (LRM-5) cable is angled and plugged into the "Laser" jack. This error will also occur if these two cables are reversed.

Follow the below steps to correct R1/Clicking error message:
  • Make sure the correct cable is connected to the correct jack and that it is fully engaged.
    Make sure there is sufficient slack in the cables to prevent them from "walking out" of the jacks.
  • Follow the Factory Reset procedure.
  • If the above suggestions does not cure the problem, email our Customer Service dept for more information.
Follow the below steps to correct R2/Clicking (Not available on Pro-3450) with "R" Yellow LED flashing error message:
  • Make sure the correct cable is connected to the correct jack and that it is fully engaged.
    Make sure there is sufficient slack in the cables to prevent them from "walking out" of the jacks.
  • If the rear antenna was not installed, go to the Factory Reset procedure. If a rear antenna was installed, continue to the next step.
  • If the rear antenna is installed, it must be programmed.

    For models 2270 and 2290
    1. Remove power from unit
    2. Press and hold the Dark button
    3. While holding the dark button, apply power to unit and hold the Dark button for 5 seconds. The "R"LED and either the Green (highway) or Yellow (City) will illuminate.

    For model 3300 and 3400
    1. Unit will display "R2 ON ?"
    2. Press the Dark button for Yes or City for No.
  • To temporarily cancel the "R2"error message on a 3300 or 3400 model, press and hold either the Dark/City/Quiet button.
  • Follow the Factory Reset procedure and see if the "R2" error goes away. If so, go to next step.
  • If the above suggestions does not cure the problem, email our Customer Service dept for more information.

Beltronics V955 Chirps on all bands for 10 minutes when cold

This is most likely caused by a poor connection between the antenna ridge and the local oscillator board. Another possibility is an uncontrolled LO chamber harmonic due to the cold temperatures. Regardless of the cause, your V955 is under warranty and Bel will fix it for free -- as long as you include a photocopy of your sales receipt. Go to Bel's web site (, and either call their 800 number or do the online chat in order to get a RMA number.

Cobra xrs757 X Band

The x-band is the considered a "trash band". It picks up things like automatic doors at supermarkets and such. About every radar detector made has an X band for non-police radar. There is no way to turn this band off on the XRS-757.

Holding down the dim button for 2 seconds turns the V alert on/off
Holding down the city button for 2 seconds turns the Spectra on/off
Holding both city and dim together for 2 seconds turns K and Ku band on/off.

Grill-mounted K-40 continues to "chirp" every 10 seconds...

I too had the same problem and called their customer service. They told me 1 chirp means a front receiver fault, 2 chirps means a rear receiver fault. They suggested I check the wiring and to switch the front receiver with the back receiver to see if the error code would "travel" with it to determine if the receiever was faulty. I did that and the problem went away. I assume I had a connection that loosened up.
