Additional Information
Cloning the Programmed Data
You can transfer the programmed data to and from a
PRO-404 scanner using an optional connecting cable
with
Ç-inch (3.5mm) stereo phone plugs on both
ends (available from your local RadioShack store or
www.RadioShack.com).
1. Turn on both scanners.
2. Connect the connecting cable to each scanner’s
PC/IF jack. CLOnE and UP to SEnd appears.
. Press e on the host scanner.
4. SEndInG appears at the host scanner.
The scanner sends the data. To exit the clone mode,
remove the cable.
CLOnE and Error may alternately appear when the
scanner receives data from a scanner other than a
PRO-404. If this happens when the scanner is receiving
data from another PRO-404, turn off the scanner and
turn it on again.
Programming with a Personal
Computer
You can also upload or download programmed data to
or from a PC using a USB cable available from your local
RadioShack store or www.RadioShack.com.
The application software is available online. Use a
search engine to find “scanner programming software.”
Follow instructions in the software package to upload
and download data.

properly after you connect a power source, you might
need to initialize the scanner.

Important: This procedure clears all information
you stored in the scanner’s memory. Only initialize the
scanner when you are sure the scanner is not working
properly.
