Care And Maintenance - Whistler MFU440 User Manual

PROBLEM: Unit falses too much.
• If alarms are POP
• If the above option doesn't help, use a higher Filter
setting or if Ka is not used turn Ka band off.
• If alarms are due to radar based traffic flow sensors or
radar based vehicle blind spot detectors, turn TFSR
ON.
PROBLEM: Unit does not record.
• If the SD card icon does not show on the unit when
powered on, please check to make sure there is a
microSD card in the microSD card slot.
• If display indicates SD CARD FULL, save any important
files then use the phone app to format the card. This
will erase ALL videos or pictures on the microSD card,
including any locked files.
If difficulties occur which cannot be solved by
information in this Troubleshooting section, please call

Help Center & FAQ page at www.whistlergroup.com,
before returning your unit for service.

Care and Maintenance

During the summer months, avoid prolonged exposure
to direct sunlight by removing your unit from the dash
when your vehicle is parked for an extended period of
time. Do not spray water, cleaners, or polishes directly
onto the unit. Do not use any abrasive cleaners on the
unit's exterior.
