Laser alert constantly goes off

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.

My beltronics police radar turns on but turns back off and I don't know why

The new Rader Unites that law inforcement use has a built-in
Blocker, Unlike the old units you could pick up the signal .
This keeps people from knowing when they are used.

Beltronics rx65 service required can I fix this problem??

This detector - along with other high-end types that require a microprocessor to analyze signals - performs a self-test when powering up. This is done for the same reasons a Power On Self Test is done on your computer. There's a lot going on inside and if just one area is malfunctioning data may not be processed correctly and in the case of the detector - resulting in aggravating false alarms or worse - not indicating an alert when needed.

You should arrange for the detector's return to Beltronics for thorough checking / realignment. Contact Beltronics via this link.

I hope this helps!

What does it mean when detector powers on and service required

When powering up, the detector goes through a short diagnostics test to make sure everything is working as expected. If there is a problem detected during this time, a message like the one you have displayed will appear. You should contact Beltronics Customer Support to arrange service with one of the methods listed at the bottom of this post.

A link to the manual for your radar detector is provided below:

Blinks service required constantly

This means that your V995 has repeatedly failed its internal self-calibration procedures. Like the message says, you need to send it to Beltronics for service.

Beltronics radar detector gives constant alert after startup.

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.
