Frequently Asked Questions - XRS 9770 COBRA
How do I mount the Cobra XRS 9770?
Use the included suction cup bracket to attach the detector to your windshield. Ensure it is at least 12 inches from the dashboard ground plane and has a clear view of the road.
What radar bands does the XRS 9770 detect?
It detects X, K, Ka, Ku bands, Laser signals, and POP radar. It also features VG-2 undetectability and Safety Warning System compatibility.
How do I turn off the voice alerts?
Press the Mute button briefly during an alert to silence it. For permanent setting, refer to the manual: hold down the City and Mute buttons for 3 seconds to cycle voice alert modes.
What does 'City' mode do?
City mode reduces false alerts from X-band signals common in urban areas. It filters out weaker signals while still providing full protection on K, Ka, and Laser bands.
How do I clean the detector?
Use a soft, dry cloth to wipe the exterior. Avoid cleaning agents, alcohol, or ammonia as they can damage the lens and housing.
Is the Cobra XRS 9770 legal to use?
Radar detectors are legal in most states except Virginia and Washington D.C. for passenger vehicles. However, use in commercial vehicles may be restricted. Check local laws.
What does the 'POP' alert mean?
POP is a very short radar burst used by some police radar guns. The XRS 9770 can detect these brief signals, but due to their nature, detection range may be limited.
How do I update the XRS 9770?
The XRS 9770 does not support firmware updates. It comes with pre-programmed detection capabilities. For future models, check Cobra's website for updates.
My detector keeps giving false alerts. What can I do?
Switch to City mode to reduce X-band falses. Also ensure the detector is not mounted behind wiper blades or metallic tint. If issues persist, perform a factory reset (hold Power + City while plugging in).
What is the warranty for the XRS 9770?
Cobra provides a 1-year limited warranty from the date of purchase. Retain your receipt. For service, contact Cobra support with proof of purchase.
