Pop Radar Guns
The Pop mode Radar Gun is a single pulse Doppler radar that is a feature
of a K and Ka (Bee III Ka radar gun) band Instant-On radar gun. It uses a
single short time pulse to measure the target vehicle’s speed. Despite the fact
that the short, single pulse makes the unit very sensitive to officer hand and
vehicle movement and reduces the range of the gun in Pop mode to 50% of
its range in Continuous Wave mode, this feature is added in an attempt to
make the radar gun invisible to Radar Detectors.
Although your detector can sense Pop signals beyond the effective range
of Pop radar guns, there will be a signal to sense only if a gun is triggered.
In addition, the Pop mode receiver section is more prone to false alerts
because of its extra sensitivity. This is especially so in urban areas. As a
result, you should consider using the Pop Detect mode only in highway
and rural situations. Cobra Electronics has included a user selectable On
or Off Pop Detect mode.

Maintenance of Your Radar Detector
Your detector is designed and built to give you years of trouble-free
performance without the need for service. No routine Maintenance
is required.
If your unit does not appear to be operating properly,
please follow these troubleshooting steps:
■
Make sure the power cord is properly connected.
■
Make sure the socket of your vehicle’s cigarette lighter
is clean and free of corrosion.
■
Make sure the power cord’s cigarette lighter adapter
is firmly seated in your cigarette lighter.
■
Check the power cord fuse. (Unscrew the ribbed end cap of
the cigarette lighter adapter and examine the fuse. If required,
replace it with a 2-amp fuse only.)
Muting an Alert
•
Your detector allows you to quickly turn Off an Audio Alert by momentarily
pressing the Mute
button. If you press the Mute button a second time
during the alert, the Audio Alert will be turned back On. After the current alert
is gone, the next alert will be heard.
Two other features are incorporated in your detector to automatically mute or
reduce the volume of alerts. See pages 14 and 16 for Intellimute and Auto
Mute modes.
Auxiliary Audio Jack
•
The Auxiliary Audio Jack can be used to connect external speakers in
environments with high ambient noise levels. The internal speaker will be
disconnected. (This uses a mini stereo audio connector.)
