That's the X band detector. X band was the first radar band used for speed enforcement, but it was replaced by K and KA bands later on. Many store security systems have X band emissions that trip false alarms on radar detectors. If your detector has a "city mode" (as mine calls it), enable that. It'll stop falsing on X band signals while still warning you about the common police bands.

Goes off frequently with no radar nearby

False alarms are common with most radar detectors. You may need to adjust your detector's settings to compensate for the interference that sets off the alarm. Check your user's manual for instructions on using the menu.

Radar dont always work and the speaker is going out

the stock speaker is only 0.5 watt. Replaced with a .75 watt. Mine and two friends both had blown speakers by they middle of the second year of use. The only other real problem was too many false alarms in town, but better safe than sorry, bang for the buck is great-saved me more than I care to think about in tickets and residual costs. Now, it's loosing it's sensitivity, still goes off for false alarms but I got a ticket and it didn't go off (not laser) and can drive by the posted speed-readout radar things they park-mount on utility pole for "us" and it wont even go off. The other day it did, one out of 20 times (by my house) it was Ka! Luckily, the local cops use KU in their crusers so it will work until I get a new one. Too bad it's dying, planned obsolecence is only a year on these I would GUESS.

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.

Getting false alarm from laser. Laser alarm keeps

If the laser continuously falses even with the car's ignition turned off, then your radar detector has an internal electronics problem. If your radar detector frequently or nearly continuously falses for laser while you are driving even in the middle of nowhere, then most likely the cause of the problem is either poor power and ground connections or electrical noise within your vehicle's electrical system.
