Cobra RAD 700i User manual

The Cobra RAD 700i is Cobra's highest performing radar detector available today and provides exceptional radar and laser detection performance especially considering its very low price.

Digital signal processing (DSP) allows the Cobra RAD 700i it to do a great job in filtering out K-band collision avoidance systems to block out many of those annoying false alerts caused by the anti-collision radar systems installed in new cars.

The Cobra RAD 480i is certainly less inexpensive, however, we strongly recommend sticking with this detector as it is by far a better value for the money.

Long Range Detection

Our Cobra RAD 700i review revealed the detector that this detector gives you the most bang-for-the-buck having greater than 10-times the capture range of a police radar guns, meaning the RAD 700i should provide you with more than ample warning to police speed trap encounters.

Laser Sensitivity

The Cobra RAD 700i is one of the best laser detectors on the market available at any price.

Filtering

New DSP integration allows for sophisticated filtering same as the more expensive models from Escort.

The Cobra RAD 700i provides exceptional filtering performance, especially at this budget price point.

Easy Advanced Programming

Q: What are the different radar detector 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 radar strike that could also be a non-radar 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: Radar 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 radar detector can pick up many X band signals (such as garage door openers) that generate false alerts.

Q: My Cobra RAD 700i 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.
