This helps to reduce false alerts and ensures that you only receive alerts from real radar guns.

The detector also has the following features:

• POP mode detection
• City/Highway mode
• Quiet mode
• Voice alerts

Features

• POP mode detection: POP mode is designed to alert you to radar guns that are used by police in short, intermittent bursts. This type of radar gun is often used in hidden locations, so POP mode can help you to avoid getting caught by surprise.
• City/Highway mode: City mode is designed to reduce false alerts from radar guns that are used in urban areas. Highway mode is designed to provide maximum sensitivity for detecting radar guns on highways.
