MAINTENANCE
MAINTAINING THE EQUIPMENT
The R4BLK requires very little physical maintenance. Wipe it with a soft cloth to keep
dust from accumulating. Check the power cord connections to keep them clean and
free of corrosion.
UPDATING THE FIRMWARE/DATABASE
Uniden recommends that you update your R4BLK firmware and database
periodically. Go to www.unidensupport.com, find your model, and check if you have
the latest firmware.
