Beltronics V955 Chirps on all bands for 10 minutes when cold
Bought this Circuit City a few months ago when the weather was still warm. Since then, we've dropped into the 30s and 40s, and it goes crazy every time we turn on the car (it stays in the car). It'll continue alerting on every band for approximately 10 minutes until the car is sufficiently warm. Of course, by that time, we're usually where we wanted to go, or we've unplugged or muted the thing.

Re: Beltronics V955 Chirps on all bands for 10 minutes...
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 (www.beltronics.com), and either call their 800 number or do the online chat in order to get a RMA number.

Laser is very sensitive to false alarms often set off when driving by an airport, or military base. Set your laser on City Mode and pay attention exactly where it goes off. Mine goes off constantly in the same place which is a air force base in Tucson, AZ. Unless you drive like crazy shut it off in the city although the cops like to use a hand held one in school zones. In 6 years of driving in Arizona I have had one real laser alert, and other than false alerts, real ones are far and few in between. Check when and where the unit alerts and use different sensitivity settings. One more thing, if your laser warning goes off you already have the ticket since the cops use them at close range unlike the radar bands. Hope this helps.
Actually, in New Mexico and Texas they are using mostly Laser now or XK band that your detector isn't picking up anyway. The way the new systems work they flash on and back off instantly and don't give detectors a chance to detect them. What you are detecting is skip from the increased Microwave signals at night. Not to worry though, they are expecting a new law to be passed that will make it illegal to even have the detector in your vehicle in Texas, the law is expected to go into effect in early Jan.
This is caused by the RD's local oscillator becoming unstable at higher temperatures due to a component which has become defective. Since this is an older radar detector model, you will have to pay a service charge to have it fixed. On the other hand, perhaps it is time to upgrade your remote installation to either the Escort 9500ci or the Bel STi-R setups? These newer models from Bel/Escort provide much better performance.
This means that the primary local oscillator couldn't be calibrated during the RD's self-calibration procedure. You could get your RD repaird by Bel/Escort, but with these older models, your best bet would be to take advantage of Bel/Escort's trade-in offer to get a current model which provides significantly better performance -- particularly with regards to Ka band radar.
Turn the unit off and then, while holding down the City and Brt buttons, turn it back on. This restores the factory default settings. Worked for mine with the exact same problem. Be sure to use the power switch though. If you just unplug the cord and plug it back in, it won't work.
