Q: What are the different bands?
A:
- X-Band 10.525 GHz +/- 25 MHz
- An older band, mostly used by automatic doors in supermarkets and rarely used by law enforcement anymore. You can eliminate this band by turning off X band in the menu.
- K-Band 24.150 GHz +/- 100 MHz
- A potential strike that could also be a non-law enforcement. Know the area as many police still utilize this band.
- Ka-Band 34.700 GHz +/- 1300 MHz
- Alert! It’s the police. One of the most common used bands by law enforcement today.
- Laser 904nm, 33 MHz bandwidth
- Alert! It’s the police. Higher law enforcement such as state troopers often use laser.
Q: What is the difference between HIGHWAY and CITY mode?
A: Detectors operate with various sensitivity levels. These levels determine the types of signals and signal ranges (bands) detected. Highway mode is the most sensitive level while City mode is the least sensitive. If the X band is left on in City mode, a detector can pick up many X band signals (such as garage door openers) that generate false alerts. The Uniden unit turns off the X band for City mode. When you are on the highway, there is less chance of picking up X band false alerts, so this Uniden unit keeps the X band on.
Q: My detector is alerting K band when no law enforcement is around.
A: One thing detectors are competing against for newer cars are the safety sensors. Cars that emit collision avoidance, lane monitoring, stop monitoring and similar features can set off the K band. To solve this issue, you can set the K band filter to ON, but this will lessen the capability to notify you to true K band alerts.
