Setting Saver; Ka Narrow Mode - Whistler GT-438Xi User Manual

OPERATION
Field Disturbance Sensor Rejection (FDSR)
Traffic Flow Sensor Rejection (TFSR)
Recently many new products that operate on police radar
frequencies have been causing nuisance alerts to radar detectors.
These radar based sensors are installed alongside the Highway
and more recently on vehicles used as lane change assist /
blind spot detectors / collision avoidance systems. TFSR when
turned ON is designed to eliminate alerts from specific Traffic
Flow sensors. FDSR when turned ON is designed to identify all
radar based collision avoidance systems that operate within the
same band as police radar and provide a brief less intrusive alert
to keep you informed and aware. A signal strength indicator
will help determine your proximity to the source without the
continued annoyance of audio.
We suggest you turn FDSR ON if you are experiencing excessive
random false alerts when behind select vehicles.

Setting Saver

Setting Saver saves your personalized settings so that when the
detector is turned off and then on again, you do not have to
re-enter them.

Ka Narrow Mode

Many countries do not share the same Ka radar guns as the
USA. Having a radar detector that scans the complete Ka
band may not be necessary if your Country is only using one
or more of the following (34.0 or 34.3 GHz). See Option Select
Mode to engage Ka Narrow mode.
